Established by the North American Lake Management Society (NALMS) in 1998, this initiative aims to foster a greater appreciation for these vital water bodies and encourage action to safeguard them. Join us this year as we explore three exciting and meaningful ways to engage with, enjoy, and protect our lakes. 1. Explore and Enjoy Your Local Lakes [gallery link="none" ids="15299,11826,15298"] Dive into Lakes Appreciation Month by soaking up the beauty of your local lakes. Whether you’re a bird-watching enthusiast, a kayaking adventurer, a fishing fanatic, or a nature lover who enjoys serene walks, getting outdoors for some lakeside enjoyment is the perfect way to show your appreciation for these natural treasures. While you're out enjoying your community lakes, participate in the NALMS "Show Your Lakes Appreciation" Photo Contest Challenge! Throughout July, share a #lakeselfie or photos of your friends, family and pets, enjoying or working on a lake or reservoir. Post your pictures on Facebook, Twitter, or Instagram with a fun or informative caption, the name of the lake, and the hashtag #LakesAppreciation. Be sure to tag NALMS in your post for a chance to win exciting prizes. The contest runs from July 1st to 31st, with winners announced on August 2nd. Always remember to respect nature by following Leave No Trace principles, ensuring our lakes stay pristine and beautiful for everyone to enjoy. 2. Dive into Citizen Science: Monitor Your Lake Monitoring the health of our lakes is essential for preserving their ecological balance and ensuring they remain vibrant, safe, and enjoyable. You can contribute to this effort by joining the annual Secchi Dip-In, a citizen science project where volunteers across North America measure water clarity using a Secchi disk. This event, organized by NALMS, helps track changes in water quality over time. By participating, you contribute valuable data to support lake conservation efforts. It's simple to get involved: obtain a Secchi disk, measure the transparency of your lake, and submit your findings online. Check out our instruction video for more info: [embed]https://m.youtube.com/shorts/zIkIx5uj8-8[/embed] In addition to measuring water clarity, keep an eye out for harmful algal blooms (HABs). HABs can produce toxins that negatively impact water quality and aquatic life. To track and report HABs consider using the bloomWatch app, a crowdsourced citizen-science tool that allows you to take photos of possible blooms and submit them through the app, sending the information to relevant state officials for further action. Monitoring and reporting HABs is a crucial step in protecting our lakes. 3. Become a Steward for Your Local Lake Volunteering for lake cleanups is a rewarding way to contribute to environmental stewardship, protect water quality, and enhance recreational spaces. Gather friends, family, or community members to spend a day picking up trash and debris around your favorite lake. This not only improves the health and beauty of the lake but also fosters a sense of community pride and collective responsibility. Many lake associations and environmental groups host regular cleanup events, so check their calendars or consider starting your own initiative. For Lake Hopatcong, New Jersey's largest lake, the Lake Hopatcong Foundation, a long-time client partner of Princeton Hydro, offers a "Lake Hopatcong Water Scout" volunteer program. Water Scouts are responsible for identifying and removing instances of the invasive water chestnut species. Volunteers survey their assigned areas at least once between mid-June and mid-July. You can choose your preferred location to volunteer by reviewing the available areas on their website map. Reach out to your local lake association to find similar opportunities for cleanup and lake stewardship activities. By raising awareness, fostering collaboration, and implementing effective strategies, we can work towards safeguarding the health and sustainability of our freshwater ecosystems. Let's come together this July to celebrate, protect, and cherish our lakes, ensuring they remain healthy and vibrant for future generations.

This achievement comes on the heels of three successfully completed dam removals since 2022, highlighting the swift progress in the revitalization efforts for Bushkill Creek. This latest endeavor holds immense significance in facilitating the passage of migratory fish species, such as alewife and American shad, to vital upstream spawning grounds. It contributes to the recovery of ecologically-beneficial freshwater mussels and the bolstering of populations of trout and other resident fish species. And, it marks another important step in returning Bushkill Creek to its natural, free-flowing state. During a recent site visit, Princeton Hydro President and Founding Principal Geoffrey M. Goll, P.E. took a moment to reflect on the years of hard work that have culminated in this significant milestone. Watch now: [embed]https://youtu.be/bZs0jn6dBcQ[/embed] In 2022, Wildlands Conservancy enlisted the expertise of Princeton Hydro to embark on a mission to remove four dams along Bushkill Creek. The successful removal of the Crayola Dam, also known as Dam #4, marked the beginning of this transformative journey. Subsequently, in 2023, Dams #1 and #3 were dismantled. Now, we celebrate the commencement of the removal of Dam #2. The map below shows the locations of all four dam removal locations on the Bushkill Creek: Bushkill Creek flows 22-miles through agricultural and suburban landscape before converging with the Delaware River. Dam #2, situated upstream from the Creek’s confluence with the Delaware River, obstructed fish passage, exacerbated local flooding, and degraded water quality, much like its counterparts. Its removal represents a significant leap forward in the restoration of Bushkill Creek's ecological health. [gallery columns="2" link="none" ids="15123,15124"] The ongoing restoration of Bushkill Creek is a testament to the dedication of over 20 stakeholders, including, but not limited to, Wildlands Conservancy, the Delaware River Basin Commission, Lafayette College, Pennsylvania Department of Environmental Protection, National Fish and Wildlife Foundation, Pennsylvania Department of Conservation and Natural Resources, and Princeton Hydro. Funding for the projects has stemmed from various sources, including a settlement following a fly ash spill from the Martins Creek Power Plant in 2005. This settlement, coupled with contributions from organizations like NFWF’s Delaware Watershed Conservation Fund and Northampton County’s Livable Landscapes program, propelled the initiative forward. As we celebrate the start of removing Bushkill Creek Dam #2, we anticipate continued progress in the revitalization of this vital waterway. Each dam removed brings us closer to realizing the vision of a thriving, free-flowing Bushkill Creek, benefitting both the environment and local communities.

Notably, Lake Hopatcong, located in Sussex and Morris Counties, remained virtually ice-free throughout the winter, with only a brief period of minor ice formation in early January. This pattern was not isolated to Lake Hopatcong; many lakes across the state and the broader Mid-Atlantic region exhibited similar ice-free conditions. Such conditions can lead to increased algal and plant growth earlier in the year. Adding to this, from January to early June 2024, 15 of New Jersey's 21 counties recorded precipitation levels 26% to 50% higher than their long-term averages. The remaining six counties, predominantly in the southern part of the state, had precipitation increases of 11% to 25% above their long-term normals. This heightened precipitation is significant as it can transport nutrients, most notably phosphorus and nitrogen, into water bodies, potentially fueling the growth of algae. Compounding these factors, long-range climate models and trends suggest that the summer of 2024 could rank among the hottest on record. The combination of a mild winter, increased precipitation, and anticipated high summer temperatures sets the stage for conditions similar to those experienced in 2019, a year marked by widespread harmful algal blooms (HABs) in numerous lakes. HABs, characterized by rapid overgrowths of cyanobacteria, present serious challenges to water quality and aquatic ecosystems. Cyanobacteria, or blue-green algae, naturally occur in aquatic environments but can proliferate rapidly under warm, nutrient-rich conditions. These blooms pose risks to human health, wildlife, aquatic species, local economies, and the overall ecological balance. The interplay between climate change and HABs is undeniable: rising temperatures and altered precipitation patterns foster conditions that exacerbate bloom occurrences. Given these circumstances, it is crucial for lake managers and water utilities to adopt proactive measures. Early and consistent sampling efforts can detect cyanobacteria and akinetes, dormant spores that contribute to bloom formation. Additionally, reducing nutrient inputs, particularly phosphorus, into waterways is essential to prevent HABs. Princeton Hydro strongly recommends that lake managers, water utilities, and concerned community members closely monitor their lakes, reservoirs, and riverways to stay as proactive as possible in managing these valuable resources. By raising awareness, fostering collaboration, and implementing effective strategies, we can work towards safeguarding the health and sustainability of our freshwater ecosystems. Together, we can address the challenges posed by HABs and protect the integrity of our water bodies. For more information about HABs, click here. Dr. Fred Lubnow, Princeton Hydro’s Senior Technical Director, Ecological Services, is an expert in aquatic and watershed management, restoration ecology, community and ecosystem ecology, and the use of benthic macroinvertebrate and fish in-stream bioassessment protocols. Dr. Lubnow has managed hundreds of lake projects and provides technical expertise for a variety of lake and watershed restoration projects. His experience in lake and reservoir restoration includes the design and implementation of dredging, aeration, chemical control of nuisance species, nutrient inactivation (i.e. alum) and biomanipulation. His experience in watershed restoration includes the design and implementation of structural Best Management Practices (BMPs), the development of Total Maximum Daily Load (TMDL) pollutant budgets, and the design, implementation and analysis of watershed-based monitoring programs.

It's important that we all do our part today and every day to honor our precious planet, promote climate action, and support sustainability. We've put together a quick list of fun ideas and helpful tips to celebrate Earth Day 2024: Build a Rain Garden in Your Yard Rain gardens are a cost effective, attractive, and sustainable way to minimize stormwater runoff and filter out pollutants. This aesthetic, low-maintenance addition to any outdoor landscape creates a functioning habitat that attracts pollinators, beneficial insects, and birds. It can also help reduce erosion, promote groundwater recharge, and minimize flooding. Princeton Hydro President Geoff Goll, P.E. and his family recently installed a rain garden at their home. They documented the process with photos and step-by-step instructions. Go here for 10 steps to building your own rain garden. Install a Rain Barrel You can help conserve water usage by incorporating water-wise practices into your daily life. Installing a rain barrel is a great place to start!

July is Lakes Appreciation Month, an annual celebration dedicated to highlighting the value and wonder of our lakes and reservoirs. Established by the North American Lake Management Society (NALMS) in 1998, this initiative aims to foster a greater appreciation for these vital water bodies and encourage action to safeguard them. Join us this year as we explore three exciting and meaningful ways to engage with, enjoy, and protect our lakes.
Dive into Lakes Appreciation Month by soaking up the beauty of your local lakes. Whether you’re a bird-watching enthusiast, a kayaking adventurer, a fishing fanatic, or a nature lover who enjoys serene walks, getting outdoors for some lakeside enjoyment is the perfect way to show your appreciation for these natural treasures.
While you're out enjoying your community lakes, participate in the NALMS "Show Your Lakes Appreciation" Photo Contest Challenge! Throughout July, share a #lakeselfie or photos of your friends, family and pets, enjoying or working on a lake or reservoir. Post your pictures on Facebook, Twitter, or Instagram with a fun or informative caption, the name of the lake, and the hashtag #LakesAppreciation. Be sure to tag NALMS in your post for a chance to win exciting prizes. The contest runs from July 1st to 31st, with winners announced on August 2nd.
Always remember to respect nature by following Leave No Trace principles, ensuring our lakes stay pristine and beautiful for everyone to enjoy.
Monitoring the health of our lakes is essential for preserving their ecological balance and ensuring they remain vibrant, safe, and enjoyable.
You can contribute to this effort by joining the annual Secchi Dip-In, a citizen science project where volunteers across North America measure water clarity using a Secchi disk. This event, organized by NALMS, helps track changes in water quality over time. By participating, you contribute valuable data to support lake conservation efforts. It's simple to get involved: obtain a Secchi disk, measure the transparency of your lake, and submit your findings online. Check out our instruction video for more info:
In addition to measuring water clarity, keep an eye out for harmful algal blooms (HABs). HABs can produce toxins that negatively impact water quality and aquatic life. To track and report HABs consider using the bloomWatch app, a crowdsourced citizen-science tool that allows you to take photos of possible blooms and submit them through the app, sending the information to relevant state officials for further action. Monitoring and reporting HABs is a crucial step in protecting our lakes.
Volunteering for lake cleanups is a rewarding way to contribute to environmental stewardship, protect water quality, and enhance recreational spaces. Gather friends, family, or community members to spend a day picking up trash and debris around your favorite lake. This not only improves the health and beauty of the lake but also fosters a sense of community pride and collective responsibility. Many lake associations and environmental groups host regular cleanup events, so check their calendars or consider starting your own initiative.
For Lake Hopatcong, New Jersey's largest lake, the Lake Hopatcong Foundation, a long-time client partner of Princeton Hydro, offers a "Lake Hopatcong Water Scout" volunteer program. Water Scouts are responsible for identifying and removing instances of the invasive water chestnut species. Volunteers survey their assigned areas at least once between mid-June and mid-July. You can choose your preferred location to volunteer by reviewing the available areas on their website map. Reach out to your local lake association to find similar opportunities for cleanup and lake stewardship activities.
By raising awareness, fostering collaboration, and implementing effective strategies, we can work towards safeguarding the health and sustainability of our freshwater ecosystems. Let's come together this July to celebrate, protect, and cherish our lakes, ensuring they remain healthy and vibrant for future generations.

The removal of Bushkill Creek Dam #2 is now underway, marking yet another remarkable milestone in the rejuvenation of this treasured limestone stream. This achievement comes on the heels of three successfully completed dam removals since 2022, highlighting the swift progress in the revitalization efforts for Bushkill Creek.
This latest endeavor holds immense significance in facilitating the passage of migratory fish species, such as alewife and American shad, to vital upstream spawning grounds. It contributes to the recovery of ecologically-beneficial freshwater mussels and the bolstering of populations of trout and other resident fish species. And, it marks another important step in returning Bushkill Creek to its natural, free-flowing state.
During a recent site visit, Princeton Hydro President and Founding Principal Geoffrey M. Goll, P.E. took a moment to reflect on the years of hard work that have culminated in this significant milestone. Watch now:
In 2022, Wildlands Conservancy enlisted the expertise of Princeton Hydro to embark on a mission to remove four dams along Bushkill Creek. The successful removal of the Crayola Dam, also known as Dam #4, marked the beginning of this transformative journey. Subsequently, in 2023, Dams #1 and #3 were dismantled. Now, we celebrate the commencement of the removal of Dam #2.
Bushkill Creek flows 22-miles through agricultural and suburban landscape before converging with the Delaware River. Dam #2, situated upstream from the Creek’s confluence with the Delaware River, obstructed fish passage, exacerbated local flooding, and degraded water quality, much like its counterparts. Its removal represents a significant leap forward in the restoration of Bushkill Creek's ecological health.
The ongoing restoration of Bushkill Creek is a testament to the dedication of over 20 stakeholders, including, but not limited to, Wildlands Conservancy, the Delaware River Basin Commission, Lafayette College, Pennsylvania Department of Environmental Protection, National Fish and Wildlife Foundation, Pennsylvania Department of Conservation and Natural Resources, and Princeton Hydro.
Funding for the projects has stemmed from various sources, including a settlement following a fly ash spill from the Martins Creek Power Plant in 2005. This settlement, coupled with contributions from organizations like NFWF’s Delaware Watershed Conservation Fund and Northampton County’s Livable Landscapes program, propelled the initiative forward.
As we celebrate the start of removing Bushkill Creek Dam #2, we anticipate continued progress in the revitalization of this vital waterway. Each dam removed brings us closer to realizing the vision of a thriving, free-flowing Bushkill Creek, benefitting both the environment and local communities.
Wildlands Conservancy, a non-profit land trust based in eastern Pennsylvania, is dedicated to the restoration of degraded stream and wildlife habitats, with a primary focus on the Lehigh Valley and the extensive Lehigh River watershed. Spanning 1,345 square miles, this watershed eventually merges with the Delaware River.
For over a decade, Princeton Hydro has been a steadfast partner to Wildlands Conservancy in their mission, collaborating on multiple dam removal projects in the Lehigh River Valley. With expertise in design, permitting, and oversight, Princeton Hydro has played a pivotal role in the removal of over 80 small and large dams/barriers across the Northeast.

Welcome to the latest edition of our Client Spotlight series, which provides an inside look at our collaboration, teamwork, and accomplishments with one of our client partners.
Today, we’re shining the spotlight on Farmington River Watershed Association (FRWA).
The FRWA is a citizen-based, 501(c)(3) nonprofit organization established in 1953 by a group of concerned citizens and community leaders to address the long-term degradation of the Farmington River. FRWA is committed to protecting, maintaining, and revitalizing the Farmington River and its watershed.
Farmington River runs for 46.7 miles along its main stem in northwest Connecticut, with major tributaries extending into southwest Massachusetts. Its longest route, originating from the West Branch, stretches 80.4 miles, making it the longest tributary of the Connecticut River. The watershed covers 609 square miles, supporting a variety of cold-water resident fish species and important habitats for migratory fish. It also serves as a critical public drinking water supply for hundreds of thousands of people in the Hartford region. Additionally, the West Branch of the Farmington is highly regarded for its exceptional trout fishery.
For this Client Spotlight, we spoke with FRWA Executive Director Aimee Petras via Zoom.
“FRWA addresses a range of challenges facing the Farmington River, including water quality, water distribution, habitat restoration, recreation, open space conservation, and the protection of wetlands and floodplains. We are dedicated to protecting and preserving the natural resources of the Farmington River Watershed through research, education, advocacy, and restoration.”
“Through research initiatives, we establish a comprehensive scientific understanding of watershed functions and health. We educate the public, government and business communities about the importance of a healthy river system. We advocate at the local, state and federal level for policies and actions that ensure the long-term protection of our watershed resources. And, we plan and implement restoration projects with long-lasting positive impacts on the river and surrounding ecosystems, engaging in hands-on stewardship through activities like fish habitat restoration, stormwater runoff reduction, and re-vegetating streambanks with native plants.”
"The Farmington River is one of the first designated 'Partnership Wild & Scenic Rivers.' Its protection is ensured through the combined efforts of federal, state, and local governments, along with various organizations dedicated to preserving the river's health. Currently, 78.6 miles of the Farmington River are safeguarded under two different designations. The Upper Farmington River has a 15.1-mile designation, and the Lower Farmington River and Salmon Brook, cover 61.7 miles.”
“To earn the 'Wild and Scenic' designation, a river must possess at least one 'outstandingly remarkable' natural, cultural, or recreational value as defined by the federal Wild and Scenic Rivers Act. This recognition is a significant achievement that our organization is extremely proud of."
Click here to learn about the National Wild & Scenic Rivers designation.
Click here to learn more about FRWA's Rainbow Dam removal advocacy and related river protection initiatives.
"Removing the dam also restored natural river flow rates and enabled American shad, alewife, and blueback herring to swim upstream through Tariffville Gorge, accessing over 20 additional miles of river. Additionally, this removal uncovered a historically scenic waterfall at a popular fishing site, replacing the neglected dam with a beautiful natural feature."
“The removal of Winchell-Smith Dam restores access for aquatic organisms to a 30-mile stretch of the Farmington River upstream of the dam within the Connecticut River watershed. This area is a historic spawning habitat for species such as American shad, alewife, blueback herring, sea lamprey, and American eel. Removing the dam helps prevent local erosion and scour, clear barriers for migratory fish, eliminate hazards for river users, and repurpose existing timbers for historic preservation and educational purposes.”

As we reflect on the winter of 2023-2024, it's evident that New Jersey experienced another unusually mild season, mirroring the winter of 2022-2023. Notably, Lake Hopatcong, located in Sussex and Morris Counties, remained virtually ice-free throughout the winter, with only a brief period of minor ice formation in early January. This pattern was not isolated to Lake Hopatcong; many lakes across the state and the broader Mid-Atlantic region exhibited similar ice-free conditions. Such conditions can lead to increased algal and plant growth earlier in the year.
Adding to this, from January to early June 2024, 15 of New Jersey's 21 counties recorded precipitation levels 26% to 50% higher than their long-term averages. The remaining six counties, predominantly in the southern part of the state, had precipitation increases of 11% to 25% above their long-term normals. This heightened precipitation is significant as it can transport nutrients, most notably phosphorus and nitrogen, into water bodies, potentially fueling the growth of algae.
Compounding these factors, long-range climate models and trends suggest that the summer of 2024 could rank among the hottest on record. The combination of a mild winter, increased precipitation, and anticipated high summer temperatures sets the stage for conditions similar to those experienced in 2019, a year marked by widespread harmful algal blooms (HABs) in numerous lakes.
HABs, characterized by rapid overgrowths of cyanobacteria, present serious challenges to water quality and aquatic ecosystems. Cyanobacteria, or blue-green algae, naturally occur in aquatic environments but can proliferate rapidly under warm, nutrient-rich conditions. These blooms pose risks to human health, wildlife, aquatic species, local economies, and the overall ecological balance. The interplay between climate change and HABs is undeniable: rising temperatures and altered precipitation patterns foster conditions that exacerbate bloom occurrences.
Given these circumstances, it is crucial for lake managers and water utilities to adopt proactive measures. Early and consistent sampling efforts can detect cyanobacteria and akinetes, dormant spores that contribute to bloom formation. Additionally, reducing nutrient inputs, particularly phosphorus, into waterways is essential to prevent HABs. Princeton Hydro strongly recommends that lake managers, water utilities, and concerned community members closely monitor their lakes, reservoirs, and riverways to stay as proactive as possible in managing these valuable resources.
By raising awareness, fostering collaboration, and implementing effective strategies, we can work towards safeguarding the health and sustainability of our freshwater ecosystems. Together, we can address the challenges posed by HABs and protect the integrity of our water bodies. For more information about HABs, click here.

Happy Earth Day! It's important that we all do our part today and every day to honor our precious planet, promote climate action, and support sustainability. We've put together a quick list of fun ideas and helpful tips to celebrate Earth Day 2024:
Rain gardens are a cost effective, attractive, and sustainable way to minimize stormwater runoff and filter out pollutants. This aesthetic, low-maintenance addition to any outdoor landscape creates a functioning habitat that attracts pollinators, beneficial insects, and birds. It can also help reduce erosion, promote groundwater recharge, and minimize flooding.
Princeton Hydro President Geoff Goll, P.E. and his family recently installed a rain garden at their home. They documented the process with photos and step-by-step instructions.
You can help conserve water usage by incorporating water-wise practices into your daily life. Installing a rain barrel is a great place to start! Using a rain barrel to collect fresh, free rainwater helps save money, conserve water AND protects the environment. Collecting water in rain barrels is a fun, affordable and effective way to reduce the amount of run-off flowing into storm drains and waterways. We’ve put together four simple steps to help you install a rain barrel in your yard.
Tulips are starting to emerge, buds are blossoming on trees and, unfortunately, invasive plant species are also beginning their annual growing cycle. Invasive species create major impacts on ecosystems near and far, but we can all do our part to reduce the spread.
Princeton Hydro Landscape Architects and Expert Green Thumbs Jamie Feinstein, RLA and Cory Speroff, PLA, ASLA, CBLP led a live “Ask Me Anything” Spring Gardening conversation via Facebook. They provided gardening tips and tricks, including:
You can play a major role in maintaining the health and safety of your community. By committing to a regular litter pick-up schedule, you can help keep your neighborhood cleaner and decrease the amount of debris and pollution entering your community waterways. Consider choosing a nearby park, lake, pond or stream for your trash clean-up activities. Whatever spot you choose, pick the place that's best for you, invite friends or family to join you, determine a regular clean-up schedule, and stick to it!
As biologists, ecologists, environmentalists, and outdoor enthusiasts, all of us at Princeton Hydro take our responsibility to care for and respect our natural surroundings very seriously. We play hard and work hard to protect our natural resources for generations to come. Happy Earth Day!
In recognition of World Water Day on March 22, it's important to acknowledge and explore the challenges affecting our freshwater ecosystems. In this blog post, we explore one of those said challenges: Harmful Algal Blooms (HABs).
HABs, characterized by rapid overgrowths of cyanobacteria, have increasingly drawn attention due to their detrimental effects on water quality and aquatic ecosystems. With the onset of spring, rising temperatures create favorable conditions for cyanobacteria growth, setting the stage for potential bloom occurrences in the months ahead. Over recent summers, lakes and freshwater bodies across the nation have faced closures and health advisories due to HAB outbreaks, underscoring the urgent need to address this issue.
Cyanobacteria, often referred to as blue-green algae, are naturally occurring microorganisms in aquatic environments. However, under specific conditions—such as warm temperatures and nutrient-rich waters—these organisms can proliferate rapidly, forming blooms that pose risks to the health of humans, wildlife and aquatic species, local economies and overall ecological balance.
The interplay between climate change and HABs is undeniable: Rising temperatures and altered precipitation patterns create favorable conditions for cyanobacteria growth, exacerbating bloom occurrences. The absence of snow cover and early ice melt further accelerates this process, allowing cyanobacteria to flourish earlier in the year. Over the past few summers, lakes and fresh-waterbodies across the nation experienced closures and health advisories as a result of HAB outbreaks, emphasizing the urgency of addressing this issue.
In light of these challenges, proactive measures are crucial for mitigating the impacts of HABs. Early sampling efforts, initiated as early as March or April, enable the detection of cyanobacteria and akinetes, dormant spores that contribute to bloom formation. Additionally, reducing nutrient inputs, particularly phosphorus, into waterways is essential for preventing HABs.
As we reflect on the significance of water resources on World Water Day, it’s imperative to recognize the importance of addressing threats such as HABs. By raising awareness, fostering collaboration, and implementing effective strategies, we can work towards safeguarding the health and sustainability of our freshwater ecosystems.
In this spirit, we invite you to join the conversation at the Harmful Algal Bloom Summit 2024, hosted by the New Jersey Department of Environmental Protection. This virtual seminar, taking place on March 27, is free to attend and offers a platform for stakeholders to exchange insights, discuss best practices, and explore innovative solutions for managing HABs.
This year's Summit, which is titled “Unlocking the Puzzle of Harmful Algal Blooms," includes a keynote address and three educational sessions - "Growth Through Reflection: Lessons Learned," "Innovative Tools and Applications," and "Beyond the Numbers" - each featuring a variety of expert presentations. Princeton Hydro Senior Technical Director of Ecological Services Dr. Fred Lubnow is presenting on "Quantifying Overwintering Cyanobacteria and How They May Impact the Monitoring and Management of HABs."

As we commemorate World Water Day 2024, let us reflect on the interconnectedness of water and life. Small actions taken today can have a profound impact on preserving water quality for future generations. Join us in making a commitment to promote and do our part to support a sustainable future for our freshwater ecosystems.
400 native plants were installed along the western shoreline of Memorial Pond in Mount Arlington, New Jersey. The planting was completed in one day by a team of 20+ volunteers, staff members from Mt. Arlington Department of Public Works (DPW), Lake Hopatcong Foundation, Lake Hopatcong Commission, Princeton Hydro, and a generous community member who volunteered his excavating equipment (and time).
The planting initiative aims to prevent shoreline erosion, promote the growth of native species, increase wildlife habitat, and improve the water quality of Memorial Pond and Lake Hopatcong. Funding for this project was secured through a grant from the New Jersey Department of Environmental Protection, awarded to the Lake Hopatcong Commission in partnership with the Lake Hopatcong Foundation.
Memorial Pond is a 0.3-acre stormwater runoff basin that gradually releases into Glen Brook, which then flows into Lake Hopatcong. The pond receives sheet flow of stormwater from the adjacent road, which contributes to nutrient and sediment loading, thus locally reducing water quality in Memorial Pond and ultimately the waters of Lake Hopatcong.
Memorial Park, which includes Memorial Pond and Glen Brook, was identified by Princeton Hydro and the Lake Hopatcong team as a priority site for improvement, targeting initiatives that reduce pollutants and excessive nutrients entering into Lake Hopatcong.
Additionally, the pond’s steeply-sloped shoreline was bare and only stabilized with large rocks at the base of the banks. In the absence of stabilizing vegetation, the pond’s banks were experiencing erosion, and there was some concern about a few mature trees along the shoreline potentially falling into the pond.
The photos above were taken in April 2023 before the planting initiative.
The plant selection and layout were designed taking into account the steep slope and presence of mature, existing trees as well as focusing on regionally native plant species that will thrive and help stabilize the eroding shoreline. The planting team, led by Princeton Hydro Landscape Architect Jamie Feinstein, RLA and Aquatics Project Manager Pat Rose, was given precise instructions on how to install the plants to eliminate washouts and ensure the root systems can embrace the soil and hold it in place.
A variety of native herbaceous plants and shrubs were chosen for the site, including pennsylvania sedge, slender mountain mint, blue flag iris, sweet azalea, smooth hydrangea, and maple-leaved viburnum.
The plants will help reduce stormwater flow, absorb excess nutrients, prevent erosion, and ultimately decrease sedimentation to the pond, while creating a visually pleasing addition to the park and providing a habitat for pollinators and birds. Overall, this project promotes a healthier and more balanced ecosystem in Memorial Park.
The photos above were taken in July 2023 immediately after the planting initiative.
The installation of these beneficial plants is part of a series of water quality initiatives on Lake Hopatcong funded by a NJDEP Freshwater Harmful Algal Bloom (HAB) Prevention & Management Grant and 319(h) Grant awarded to Lake Hopatcong Commission in partnership with the Lake Hopatcong Foundation.
Additional initiatives included in the watershed implementation and HABs management plan are, the installation of:
floating wetland island (FWI), which are a low-cost, effective green infrastructure solution designed to mimic natural wetlands in a sustainable, efficient, and powerful way. FWIs improve water quality by assimilating and removing excess nutrients; provide valuable ecological habitat for a variety of beneficial species; help mitigate wave and wind erosion impacts; provide an aesthetic element; and add significant biodiversity enhancement within open freshwater environments;
biochar filtration bags, which improve water quality by removing phosphorus from waterbodies. Biochar can be placed in floatation balls, cages, or sacks, which are then tethered along the shoreline and in critical locations throughout the waterbody; and
nanobubble aeration system, which increases the concentrations of dissolved oxygen in the water, prevents stagnation of water, increases circulation, disrupts thermal stratification which provides “through-column” mixing, and minimizes the occurrence of HABs.
“Paired with biochar filters attached to buoys in the pond and continued monitoring and maintenance of the plantings by the DPW, these steps will set a healthy precedent for what can be achieved through working together with funders, local partners, science, and landscape architecture,” said Feinstein, who sourced plant material, provided logistics and co-led the planning and volunteer planting event along with Rose.
Princeton Hydro's Landscape Architect, Cory Speroff PLA, ASLA, CBLP, designed the planting plan, and Will Kelleher and Jackson Tilves from the Aquatics Team participated in the plant installation event with Feinstein.
Princeton Hydro is also authoring and supplying a maintenance manual that provides guidance on seasonal care of the plantings, when to remove the herbivory protection fencing, pruning, watering, and other activities that support the long term success of the planting initiative.
“This collaborative effort to enhance water quality serves as a prime example of how seemingly simple actions can have a meaningful impact on safeguarding our water resources for the benefit of future generations,” said the Lake Hopatcong Foundation.
The photos above from left to right: June 2023 before the planting; July 2023 during the planting (photo by Lake Hopatcong Foundation Executive Director Kyle Richter); and July 2023 immediately after the planting.
Princeton Hydro has been working on Lake Hopatcong, New Jersey’s largest Lake, for 30+ years, restoring the lake, managing the watershed, reducing pollutant loading, and addressing invasive aquatic plants and nuisance algal blooms.

Today, we’re shining the spotlight on Citizens United to Protect the Maurice River and Its Tributaries, known commonly as CU Maurice River, a 501(c)3 nonprofit membership organization dedicated to protecting the Maurice River Watershed’s natural integrity and cultural heritage.
The Maurice River, located in south-central New Jersey, was designated a National Wild and Scenic River by Congress in 1993. It draws from a drainage area of 385 square miles and meanders south for 50 miles, through Southern New Jersey primarily in Cumberland County. Headwaters are in parts of Gloucester, Salem, and Atlantic Counties, emptying into the main stem of the Maurice; from there it flows into Delaware Bay. The major tributaries of the river are Scotland Run, Muddy Run, Menantico Creek, Muskee Creek, and the Manumuskin River. There are about 20 small lakes in the watershed, the largest of which is Union Lake at 950 acres.
As South Jersey’s leading watershed organization, CU Maurice River engages in fieldwork, advocacy, research, and education initiatives generating and contributing to a greater understanding of the local environment and wildlife.
For this Client Spotlight, we spoke with CU Maurice River Executive Director Karla Rossini via Zoom:
"CU Maurice River is a very grassroots, very local organization. One of our core strengths is community involvement. In everything we do, we try to invite the largest section of community that we possibly can. Whether that’s to participate in educational opportunities or participate in volunteerism or become an advocate of our local resources, we really make it our goal to develop and foster stewardship within the community."
"We're very excited about the work we're doing with the WheatonArts & Cultural Center, a nonprofit 501(c)(3) organization with a mission to engage artists and audiences in an evolving exploration of creativity.
Over the years, CU Maurice River has worked with WheatonArts to design and implement various best management practices throughout its 45-acre campus. We’ve installed vernal pools, purple martin gourds, a blue bird trail, a nature trail, and a massive rain garden. The projects support water resources on site and beyond, revitalize and preserve natural habitats, and provide an invaluable community resource for promoting eco-friendly land management, stewardship, and nature exploration.
WheatonArts and CU Maurice River also launched a four-week nature journaling course, which will take place on Wednesdays and Thursdays, from August 3 to August 25 (2023). Kids get to spend time outdoors while growing their science knowledge, appreciation for nature, and artistic ability. Nature journaling is a way to creatively connect and build a deep, lasting relationship with the natural world.
The CU Maurice River team does the scientific teachings, and the WheatonArts team does the art teachings. So for example, CU Maurice River will teach about the anatomy of a tree, how a tree functions, why an Oak tree produces acorns, and the ecosystem services a tree provides. And, WheatonArts teaches the kids how to draw and paint a tree, how to make an acorn look round, and how to get the shades of the brown tree trunk just right.
Another interesting aspect of the program is that it also highlights the history of communication in nature exploration. Darwin had to draw his pictures to describe his findings. Mary Treat had to draw her discoveries. Audubon had to illustrate his birds. And, let’s face it, most of the best ID books aren’t photo books, they’re illustrated books. So, this program focuses on the importance of art in science."
"The first time I encountered Princeton Hydro was at a Musconetcong River event where Princeton Hydro was presenting on dam removal and the restoration of trout habitat on the Musconetcong. Then, later that year, at the Annual Delaware River Watershed Forum, I met Dana Patterson (Princeton Hydro's Director of Marketing and Communications). We got to talking about a variety of different projects we could explore together, and it's been a really great partnership ever since. I’m pretty sure I've given Dana and Christiana Pollock (Princeton Hydro's Director of Restoration and Resilience) some wacky ideas to figure out, but Princeton Hydro has always been very supportive AND realistic.
Since then, we’ve contracted with Princeton Hydro to do a feasibility study on the Centerton Dam removal. We’re also working with Princeton Hydro to do an ArcGIS StoryMap of the Paddle Trails in the Maurice River Watershed. And, we've got some other exciting things in the works that I'm not at liberty to discuss publicly today, but stay tuned for more great things as a result of CU Maurice River's collaboration with the Princeton Hydro team.
Princeton Hydro has really provided a lot of support and guidance, and I am eternally grateful for their partnership."

Whether you're a birding enthusiast, a photography pro, a boating lover, a paddle-boarding champ, or someone who enjoys leisurely strolls, it's time get lakeside to enjoy your favorite activities. Stay in the loop with your local lake association's calendar and discover fun community events. If you're in the Berks County, Pennsylvania area, join PALMS on July 14 at Blue Marsh Lake for their community sunset paddle and float event. Capture your lake love and spread the joy - share your adventure photos on social media using #LakesAppreciation and inspire others to embrace lake appreciation too! Whatever fun adventure you choose, always remember to respect our natural landscape and treat it with care. Click here for a few tips to help you enjoy your Lakes Appreciation Month outings responsibly and sustainably.
To encourage everyone in the family to get outside together and enjoy the lakes that surround them, NALMS is created a family BINGO Challenge game. The BINGO board features a variety of activities, like "Have a picnic at your favorite lake," "Go wildlife or bird watching," and "Pick up trash around your favorite lake." As you complete each activity, you mark the square with an X. Once you complete all activities in a row or diagonally, you get “BINGO." Fill the card completely for maximum lake appreciation! This simple game is designed to stir creativity, curiosity and action, and is intended to act as a reminder for us all to pause and appreciate something we often take for granted. Play it, share it, and enjoy!
In celebration of Lakes Appreciation Month, lake associations nationwide are hosting family-fun events, volunteer opportunities and community gatherings. On July 14, Pennsylvania Lake Management Society invites you to join them at Blue Marsh Lake for a community sunset paddle/float. On July 20 at the Stone Water lakefront restaurant, Lake Hopatcong Foundation is hosting its 11th Anniversary Gala & Auction, which aims to bring together community members who are passionate about Lake Hopatcong, to have fun and raise funds critically needed to protect the environment and enhance the experience on and around Lake Hopatcong. Organize a community trash pick-up day at a nearby lake or get in touch with your local lake association to find out how you can get involved.
The “Secchi Dip-In” is an annual citizen science event where lake-goers and associations across North America use a simple Secchi disk to monitor the transparency or turbidity of their local waterway. Created and managed by NALMS, volunteers have been submitting information during the annual Dip-In since 1994. NALMS invites you to join this international effort to track changes in water quality! Get all the Dip-In details here. And, for detailed instructions for how to use a Secchi disk, check out our tutorial.
In addition to the Secchi Dip-In, you can support your favorite lake by identifying and reporting harmful algal blooms (HABs) and invasive species. And, the bloomWatch App is a great educational resource and tracking tool! By using the app on your smartphone, you can contribute to a nationwide community science program dedicated to tracking and documenting the occurrence of potential HABs. Click here for a brief video on how to use the bloomWatch app. And, for more information about HABs, click here to view a presentation given by Dr. Fred Lubnow at the NALMS 42nd Annual International Symposium.

Today, we’re shining the spotlight on Riverkeeper, a 501(c)3 nonprofit membership organization headquartered in Ossining, New York. The organization is committed to protecting and restoring the Hudson River from source to sea and safeguarding drinking water supplies through advocacy rooted in community partnerships, science, and law.
For this Client Spotlight, we spoke with Riverkeeper’s Senior Habitat Restoration Manager George Jackman, PhD via zoom:
A: We are the first Keeper organization in the world. We began in 1966 as the Hudson River Fishermen’s Association, an environmental watchdog and enforcement organization founded by a group of concerned fishermen. In 1986, we officially changed our name to Riverkeeper. We've helped set worldwide standards for waterway and watershed protection, and continue to serve as the model for more than 300 Keeper programs around the globe.
As New York’s clean water advocate, Riverkeeper is the unique voice in the Hudson Valley that is continually speaking-up to protect the integrity of the water, the creatures that call it home, and our surrounding communities. We are a voice of environmental justice for the people of Hudson Valley, advocating for communities that have often been marginalized or placed in disadvantaged situations that are now at the mercy of climate change. We are always striving for a fishable, swimmable, and drinkable Hudson River and a healthy watershed.
A: We value clean, reliable drinking water and an equitable justice for all people. We value a healthy, ecologically-balanced environment and clean, sustainable forms of energy. We value free-flowing rivers that are resilient and teeming with life. We value stewardship of the Hudson River and its watershed. And, last but not least, we value all of our members, volunteers, partners, supporters, and neighbors who play a primary and vital role in protecting our local environment.
A: I have to tell you, some of the work we do is not incredibly exciting, but it's incredibly important.
We do a lot of work to strengthen the laws and regulations that impact New York’s water resources. We advocate for environmental justice, and we help our fellow community members understand the legislative process and how to get involved in garnering support for legislation that protects our Hudson River, its tributaries, our watershed, wetlands and surrounding areas. Strong environmental policy may not be the most exciting thing, but it is one of the best tools we have.
And, it is very exciting when we win. Riverkeeper has taken on some of the largest corporations on planet Earth - General Electric, General Motors, Exxon - and we've won! The work isn’t easy; sometimes it can be a long, persistent slog. But, you know what? We’ve stayed the course and we've prevailed. Every time we win for the fish, it’s a big win for all of us, and for me that’s incredibly exciting and fulfilling.
The removal of the two defunct dams that George mentions in the video clip – Strooks Felt Dam and Furnace Brook Barrier #1 – marked an important milestone in the Riverkeeper’s journey to “Undam the Hudson River” and restore fish passage between the Hudson and the Atlantic Ocean.

A: We have a great citizen science water sampling program; it’s actually one of the first community science initiatives in the world related to sampling water.
It begins every April and volunteers have to commit to 6-months of water quality sampling. The samples are collected from the water’s edge by Riverkeeper-trained community scientists. We test for salinity, oxygen, temperature, suspended sediment, chlorophyll, and Enterococcus (Entero), a fecal indicator bacteria. It’s quite an unprecedented scope for a citizen science sampling initiative. We compile the data into “How’s the Water” reports and tributary watershed reports, and post them to our website.
One of the wonderful things about the citizen science program is that we’re working with younger generations, training them on how to take samples and make observations, and helping them learn about the river. We’re trying to create a deeper connection between the river and its surrounding community members, especially our younger groups, and teach everyone how to be stewards for the river and protect the rivers’ many creatures.

A: I’ll just close by saying, I’ve had a great experience working with Princeton Hydro. And, we look forward to Princeton Hydro bidding on future Riverkeeper projects, and hopefully working with them in the future.
A big thanks to George and Riverkeeper for taking part in our Client Spotlight Series!
