Today, we delve into the fascinating world of Geographic Information Systems (GIS) analysis through the eyes of Tara Srinivasan. Tara, an environmental staff scientist for the Restoration & Resilience team and a GIS analyst, combines her passion for environmental research with the power of geospatial data to support sustainable projects that enhance ecosystems and communities alike. GIS is a powerful technology used to study, analyze and visualize geospatial data. In Tara’s role at Princeton Hydro, GIS serves as both a creative and analytical tool, enabling her to generate and explore detailed maps of environmental conditions at project sites, such as vegetation, soils, topography, and water bodies. This process aids in identifying restoration needs, addressing challenges, and developing innovative solutions. Let’s embark on a journey through a typical day in Tara’s role and uncover how her expertise helps shape Princeton Hydro’s environmental restoration projects. Diving Into Data Tara usually starts her day in the office, preparing to analyze data for a particular project. Using GIS software like ArcGIS, she examines historical and current imagery of the site, overlays habitat features, and maps property boundaries. These analyses help Tara and the project team understand the site’s existing conditions, such as watershed boundaries and the presence of threatened or endangered species. “GIS allows us to study locations remotely, uncover patterns and features that might not be obvious on the ground, and understand how a place interacts with its surrounding environment,” Tara explains. “By incorporating extensive environmental data from local, state, and national resources, collected by both public and private organizations, I can gain a comprehensive view of a project site before we even set foot in the field.” From calculating the impacts of a proposed restoration project to mapping flood conditions under various climate scenarios, Tara’s work ensures that Princeton Hydro’s environmental solutions are informed by robust spatial data and cutting-edge technology. One project Tara is especially proud of is Princeton Hydro’s contribution to the Trenton Vulnerability Assessment, part of the Resilient NJ initiative administered by the NJDEP Bureau of Climate Resilience Planning. “We modeled flooding and urban heat islands based on current data and future projections of climate change, and created a mapping tool that overlaid hazard areas with Trenton’s critical facilities, community assets, cultural and ecological resources, and vulnerable populations,” she shares. Tara had the opportunity to present this data to Trenton residents, who shared their questions and ideas for solutions that the City incorporated into its climate planning efforts. “It was a great way to engage with our local Trenton community, get in-person feedback on our maps, and see the potential that GIS and environmental data have in informing social conversations,” Tara adds. Delineating a Watershed Today, Tara is focused on defining the boundaries of a watershed surrounding a small lake. In this video, she walks us through her step-by-step process for watershed delineation: [embed]https://youtu.be/qPi_FvJRGcQ[/embed] Collaborating Across Teams Collaboration is a key part of Tara’s role. On a typical day, she meets with Princeton Hydro’s regulatory team to discuss GIS findings that inform project permitting and compliance. These partnerships enhance her work, ensuring that data analyses align with project goals and regulatory standards. Tara also communicates her findings to clients and stakeholders who may not have technical GIS backgrounds. She uses intuitive maps, symbols, and colors, like blue for water and green for forests, to help stakeholders understand complex concepts at a glance. “Maps are a powerful thing,” Tara says. “They can bring people up to speed quickly and convey information in a way that words alone cannot.” When maps become more intricate, Tara incorporates supplementary visuals, such as tables and graphs, to provide additional clarity. Her ability to bridge technical expertise with accessible communication is crucial for guiding clients through project decisions. Fieldwork and Fresh Air Although much of her work is office-based, Tara occasionally heads out into the field to collect data or monitor project sites. Equipped with GPS tools and field notebooks, she assesses topography, vegetation, and other site-specific details that feed back into her GIS analyses. “Fieldwork provides a fresh perspective,” Tara notes. “It’s a great opportunity to see how projects are implemented and to observe how the environment evolves over time.” Whether delineating watersheds or monitoring post-construction conditions, these outings connect Tara’s technical work to the tangible landscapes she aims to restore. Overcoming Challenges with Innovation and Care Tara thrives on finding innovative solutions to challenges in her work, such as optimizing software processes and addressing gaps in available data. Her meticulous organization of databases, attention to detail, and commitment to accuracy ensure that her outputs are both reliable and impactful. When data is limited, Tara ensures transparency by clearly communicating any uncertainties, fostering trust and confidence in her analyses. Tara also approaches her work with a strong ethical lens, carefully considering the implications of GIS analyses on communities and ecosystems. “When you look at a map of a stream, lake, wetland, or forest in an urban area, it’s important to notice the houses, schools, businesses, parks, and other features that surround them,” Tara explains. “Our projects impact both the environment and people. GIS helps us examine a large area and assess our impact so we can minimize any temporary or permanent effects, both legally and ethically.” She notes that GIS can even identify already disturbed areas for construction access, helping preserve healthier habitats. Continued Inspiration Tara’s love for maps dates back to her childhood, when she was captivated by the intricate, hand-drawn maps in fantasy novels. Her fascination grew through exploring Google Earth, imagining future travels, and observing how geography shapes civilizations. This passion now drives her professional journey, where she uses GIS to merge her analytical skills with creativity. “I’ve always been a visual learner, so I find something grounding about orienting yourself on a map,” Tara shares. When she’s not working, Tara enjoys wildlife photography hikes, baking experiments, and writing music for her ukulele—a testament to her creativity both inside and outside the office. For Tara, GIS is more than a tool; it’s a gateway to understanding and addressing environmental challenges. Her work at Princeton Hydro highlights the versatility of GIS in projects ranging from wetland restoration to climate change resilience. Reflecting on her role, Tara says, “What I love most about GIS is its ability to bring environmental stories to life, helping people connect with the places they care about in a meaningful way.” [gallery link="none" ids="16713,16712,16711"] Through her dedication and expertise, Tara embodies the spirit of innovation and environmental stewardship that defines Princeton Hydro’s mission.

The program hopes to enrich young participants, who may not have the opportunity to explore open spaces in their community, with hands-on environmental field experience under the tutelage of NJDEP professionals and mentors. This year’s participants consisted of youths from several different community-based organizations. These partners include Neighborhood Improvement Association (Trenton), Rutgers-Camden, The Work Group (Camden), Ranch Hope (Salem), Boys and Girls Club of Garfield, Groundwork Elizabeth, Ironbound Community Corporation (Newark), and United Community Corporation (Newark). Over six weeks, eight community organizations guided participants as they engaged with professionals to explore careers in water and air monitoring, natural resource management, wildlife conservation, and other related fields. Additionally, a new component of the program introduces "community project days," where participants actively contribute to environmental projects within their neighborhoods. These projects enable participants to make a positive impact on their communities, fostering a sense of civic pride and environmental stewardship. Activities may include park cleanups, installing educational exhibits, and establishing community gardens. [caption id="attachment_13546" align="aligncenter" width="1230"] The youth program participants gather together with their certificates for a final group photo at NJDEP.[/caption] The program has been expanded to include a full day of rehearsal, with a focus on public speaking abilities and mock interviews, regarded as integral components of professional development. Throughout the summer, participants will engage in resume and cover letter writing sessions and attend presentations led by guest speakers. In addition to fostering personal and professional growth, participants devoted a substantial amount of their time to honing technical skills through hands-on activities. These activities included simulating environmental impact investigations, collecting macroinvertebrates from a stream to gauge water quality, interacting with fish at a state trout hatchery, and designing a park in collaboration with Green Acres staff. To further enrich their understanding, the program also incorporates a visit to the regional headquarters of the U.S. Environmental Protection Agency. As part of this initiative for the third year in a row, the NJDEP's Division of Land Resource Protection Mitigation Unit invited Princeton Hydro and Mercer County Park Commission to host three sessions at John A. Roebling Park. Under the guidance of Princeton Hydro mentors Mark Gallagher, Dana Patterson Grear, and Mike McGraw, the team educated young participants about invasive species and the importance of restoring native landscapes. The initiative exposed attendees to the varied roles of environmental scientists, water resource engineers, geologists, restoration ecologists, wildlife biologist, pesticide applicators, regulatory compliance specialists, and communications professionals, thereby enhancing their understanding of these professions and sparking a fascination for the natural world. The Abbott Marshlands in Trenton, New Jersey The program began at Tulpehaking Nature Center like in previous years. After representatives from Mercer County Park Commission and Friends of the Abbott Marshlands introduced the site's history, Princeton Hydro discussed career opportunities in conservation and gave a brief overview of ongoing restoration efforts in the park to eliminate the invasive Common Reed (Phragmites australis), and NJDEP representative, Jessica Klein, gave a presentation about her work in wetland mitigation. Before venturing into the Abbott Marshlands, the northernmost freshwater tidal wetlands along the Delaware River, the Princeton Hydro team conducted a health and safety briefing. They highlighted potential risks and exposures to ensure everyone's awareness. This briefing is a crucial part of prioritizing the safety of all participants in our work. [gallery link="none" ids="15638,15639,15629,15633,15634,15630,15632,15631,15637"] Shortly after setting out on the road to the site, the students received an additional lesson. Mark directed their attention to a nearby tree where poison ivy - a native plant - had stealthily climbed up the trunk. To their surprise, the young participants had mistaken the trailing vines for branches of the tree. This observation highlighted the remarkable ability of poison ivy to adapt to its surroundings, finding innovative ways to persist and thrive in its environment. As the second group continued their journey down the path, they encountered a Fowler’s toad. Initially, its slippery texture startled them, but they quickly realized the frog's harmless nature. Through gentle pats on its head, they gained a newfound appreciation for these fascinating creatures, transforming their initial fear into a sense of wonder and respect. Venturing through the marshland, the young explorers gained insights into wetland delineation. They witnessed the fascinating process of using a hand auger and a Munsell Soil Color Book to identify and understand the unique characteristics of wetland soils. In a delightful exploration of local flora, participants delved into the art of species identification using a specialized field guide. They learned to distinguish invasive plant species from their native counterparts, such as sensitive fern, which they were able to see during a short nature walk on a trail back to the nature center. In a seemingly unremarkable area of the riverbank, the third group stumbled upon a startling discovery. Amidst the lush vegetation, a highly toxic plant known as poison hemlock flourished. The students were taken aback by its presence in an otherwise ordinary location. They had never encountered such a hazardous plant in their previous studies. The poison hemlock, with its delicate white flowers and feathery leaves, belied its deadly nature. The students were captivated by its beauty, but the instructors cautioned them against touching. The encounter with poison hemlock and poison ivy served as a valuable lesson for the students. They realized that even in seemingly ordinary places, hidden dangers could lurk. They developed a newfound respect for the power of nature and the importance of exercising caution when exploring unfamiliar environments. [gallery link="none" columns="2" ids="15640,15641"] Ending the day, participants from the first group had the privilege of attending a lesson conducted by Wildlife Biologist Mike McGraw. With the assistance of the Nature Center's resident corn snake, Mike introduced the students to the fascinating world of reptiles. Overcoming their initial apprehension towards these slithery creatures, the students discovered that there was much more to snakes than they had previously imagined. Mike dispelled common misconceptions and fears, explaining that snakes are not inherently dangerous creatures but rather play a vital role in maintaining the balance of ecosystems. The NJDEP Youth Inclusion Initiative began on July 8 and culminated on August 16 with a graduation and NJDEP Career Day where students had the opportunity to meet and discuss career options with various organizations who tabled at the event, including Princeton Hydro.

Mark directed their attention to a nearby tree where poison ivy - a native plant - had stealthily climbed up the trunk. To their surprise, the young participants had mistaken the trailing vines for branches of the tree. This observation highlighted the remarkable ability of poison ivy to adapt to its surroundings, finding innovative ways to persist and thrive in its environment.
As the second group continued their journey down the path, they encountered a Fowler’s toad. Initially, its slippery texture startled them, but they quickly realized the frog's harmless nature. Through gentle pats on its head, they gained a newfound appreciation for these fascinating creatures, transforming their initial fear into a sense of wonder and respect.
Venturing through the marshland, the young explorers gained insights into wetland delineation. They witnessed the fascinating process of using a hand auger and a Munsell Soil Color Book to identify and understand the unique characteristics of wetland soils. In a delightful exploration of local flora, participants delved into the art of species identification using a specialized field guide. They learned to distinguish invasive plant species from their native counterparts, such as sensitive fern, which they were able to see during a short nature walk on a trail back to the nature center.
In a seemingly unremarkable area of the riverbank, the third group stumbled upon a startling discovery. Amidst the lush vegetation, a highly toxic plant known as poison hemlock flourished. The students were taken aback by its presence in an otherwise ordinary location. They had never encountered such a hazardous plant in their previous studies. The poison hemlock, with its delicate white flowers and feathery leaves, belied its deadly nature. The students were captivated by its beauty, but the instructors cautioned them against touching.
The encounter with poison hemlock and poison ivy served as a valuable lesson for the students. They realized that even in seemingly ordinary places, hidden dangers could lurk. They developed a newfound respect for the power of nature and the importance of exercising caution when exploring unfamiliar environments.
Ending the day, participants from the first group had the privilege of attending a lesson conducted by Wildlife Biologist Mike McGraw. With the assistance of the Nature Center's resident corn snake, Mike introduced the students to the fascinating world of reptiles. Overcoming their initial apprehension towards these slithery creatures, the students discovered that there was much more to snakes than they had previously imagined. Mike dispelled common misconceptions and fears, explaining that snakes are not inherently dangerous creatures but rather play a vital role in maintaining the balance of ecosystems.
The NJDEP Youth Inclusion Initiative began on July 8 and culminated on August 16 with a graduation and NJDEP Career Day where students had the opportunity to meet and discuss career options with various organizations who tabled at the event, including Princeton Hydro.

We are thrilled to announce the newest addition to our fleet: The Marsh Master® 2MX-KC-FH! This multi-functional, eco-friendly, and fully amphibious machine is specifically designed to work in wetland environments with minimal disruption to the delicate ecosystem.
One of the Marsh Master®'s primary roles is combating invasive and nuisance plant species, including the notorious non-native Phragmites australis, also known as Common Reed. Utilizing its innovative leveling and cutting mechanisms, this powerhouse of a machine efficiently knocks down and chops up sprayed or winter-weakened vegetation. Equipped with two powerful rotary blades, it effortlessly cuts through dense underbrush and tall marsh grasses, effectively controlling invasive weeds and problematic plant growth.
"We are committed to offering more non-chemical alternatives for aquatic invasive species control. The Marsh Master® 2MX-KC-FH is the second marsh buggy in our fleet," said Geoffrey M. Goll, President of Princeton Hydro. "This model is larger and more powerful, allowing us to cover more ground in a shorter period of time. Adding this machine to our fleet is an important investment in achieving our firm's environmental stewardship goals."
What sets the Marsh Master® apart is its versatility and low environmental impact. With its lightweight construction and advanced weight distribution system, it exerts low ground pressure and boasts high floating capacity. This allows the Marsh Master® to operate seamlessly on water, in deep or shallow depths, and on dry land without disturbing sensitive environments like nature preserves, wetlands, and canal banks. Its highly maneuverable design ensures easy passage through narrow channels and around hazards, making it the ideal choice for a wide range of applications.
But the Marsh Master® is not just a one-trick pony. With a wide array of tools and accessories, it can perform a variety of functions, from weed cutting and harvesting to debris removal to excavation to soil sampling.
During a recent project in Middlesex County, we put the Marsh Master® to the test to clear an area overrun with Phragmites australis. These invasive weeds not only create dense thickets unsuitable for native fauna but also outcompete local vegetation, leading to a decrease in plant diversity. Thanks to the Marsh Master®'s efficient cutting and rolling capabilities, we were able to expose the marsh plain and get it ready for planting of native vegetation in the Spring. This is just one example of how the Marsh Master is making a tangible difference in restoring delicate ecosystems.
Through a combination of prevention, early detection, eradication, restoration, research and outreach, we can protect our native landscapes and reduce the spread of invasive species. Learn more about our invasive species removal and restoration services.

Here at Princeton Hydro, our team members are committed to learning new technologies, staying ahead of regulatory changes, expanding their knowledge, and earning professional certifications in order to better service our clients and the public.
Today, we are proud to put the spotlight on three team members who recently achieved new professional certifications from the Maryland Department of Natural Resources (MDNR).
Environmental Scientist Duncan Simpson, PWS, earned his Maryland Biological Stream Survey (MBSS) Fish Crew Leader certification. He is the only person to have earned this prestigious certification in 2020. He also successfully completed the MBSS Physical Habitat Assessment.
Staff Scientists Ivy Babson and Jesse Smith passed the written MBSS Benthic Macroinvertebrate Sampling Certification test, and successfully completed the related field audit.
The MBSS program was started by the Maryland Department of Natural Resources in 1993 in order to improve consistency among all individuals in Maryland using MBSS habitat assessment protocols so that habitat data are comparable. The MBSS was Maryland's first probability-based or random design stream sampling program intended to provide unbiased estimates of stream conditions with known precision at various spatial scales ranging from large 6-digit river basins and medium-sized 8-digit watersheds to the entire state. This program is a cost-effective and efficient way to characterize Maryland's 10,000+ miles of freshwater streams.
Duncan attended the Fish Crew Leader and Physical Habitat Assessment certification trainings, which were held virtually due to COVID-19. Following the trainings, he successfully passed the required written exams and field audits.
For the habitat assessment field audit, Duncan had to complete an assessment and arrive at the same conclusions as the MBSS experts. He assessed a stream reach for several instream and upland habitat characteristics including audits of bank erosion; bank formation and substrate; stream character; woody debris; max depth; channelization; and riparian vegetation.
The fish crew leader audit required Duncan to lead a team of individuals on a mock fish sampling event during which he was responsible for overseeing that the crew using the MBSS Round Four Sampling Protocol. In order to pass the audit, Duncan had to illustrate his intimate familiarity with every aspect of MBSS sampling and have at least three years of experience with MBSS sampling or with another comparable ecological field sampling effort.
“I first learned about the MBSS certification in 2010 and have been hoping to take the training and earn the certification ever since. I truly admire and respect the scientific rigor of MBSS, so to be recognized with this prestigious certification is a great milestone in my career and something that I’m very proud of.” - Duncan Simpson
For Staff Scientists Ivy and Jesse, the MBSS Benthic Macroinvertebrate field audit required that they collect kicks/jabs in twenty locations within the stream reach, located within the Elbow Branch in Susquehanna State Park. These twenty kicks/jabs were divided up into different microhabitat types depending on which were most dominant in the reach. The MBSS auditor simultaneously collected the same number of each microhabitat type.
The twenty kicks performed by each sampler were compiled into one sample that was preserved and sent to the Maryland State Labs for analysis. In order to pass the audit, Jesse and Ivy’s Benthic Index of Biotic Integrity (a metric based on the diversity and tolerance of the organisms collected) had to be within one unit of the auditor's. Additionally, their successful audit hinged on having the correct supplies and on decontaminating their gear to prevent the spread of invasive species.
"The training experience with MBSS allowed me to gain a deep appreciation of the role that benthic macroinvertebrates hold in our freshwater ecosystems. I’ve been able to develop a unique skillset to help my, and ultimately others’, understanding of benthic macroinvertebrate species richness and what they indicate in terms of water quality that contribute to the health of these special ecosystems." -Ivy Babson
"I've had an interest in aquatic macroinvertebrates since college, and this training experience with the MBSS helped me further appreciate the process that goes into studying them and the ecosystems in which they live. This certification will allow me further opportunities to work with these organisms in the future, and I look forward to more work in this area." - Jesse Smith
In total, the Maryland Department of Natural Resources offers five certification opportunities in MBSS protocols. The certifications include benthic macroinvertebrate sampling, benthic macroinvertebrate laboratory processing and subsampling, fish crew leader, fish taxonomy, and physical habitat assessment. In some cases, prerequisite certifications and trainings are required in order to apply and complete the DNR’s MBSS certifications. For example, in order to achieve the benthic macroinvertebrate taxonomy program, a previous Society for Freshwater Science certification is required.
Attendance at MBSS spring and summer trainings is a partial requirement for most of the certifications. Participants must pass written tests and field audits, as well as additional tests and quality assurance procedures. Passing a laboratory audit and a written test is also required for the benthic macroinvertebrate laboratory processing and subsampling certification.
Congratulations to Duncan, Ivy, & Jesse!

Princeton Hydro has grown from a small, four-person firm operating out of a living room to a 60+ person business with six office locations in the Northeast and a satellite office in Colorado. Over the last two decades, we’ve restored many miles of rivers, improved water quality in hundreds of ponds and lakes, and enhanced thousands of acres of ecosystems in the Northeast.
This year, we are feeling extra grateful for those who have supported our business and helped us further our mission during these difficult times. As we reflect on 2020 and set our sights on 2021, we have many successes to celebrate. Here's a look at our top 10 successes of the year:
Our team installed one fish ladder and oversaw the removal of five dams in four states. In New York, in partnership with Riverkeeper, Princeton Hydro oversaw the removal of two dams on tributaries to the Hudson River: Strooks Felt Dam on the Quassaick Creek in Newburgh and Barrier #1 on Furnace Brook in Cortlandt. The dams were the first barriers for fish movement upstream from the Hudson River. In Connecticut, the Slocomb Dam along Roaring Brook in South Glastonbury was removed, restoring American eel and trout passage. In Massachusetts, the Horseshoe Mill Pond Dam in Wareham was removed, opening over 3 miles of fish habitat on the Weweantic River, Buzzards Bay’s largest freshwater river. Here, migratory fish can now swim unimpeded from Buzzards Bay to lay their eggs in fresh water upstream for the first time in 200 years. In New Jersey, we led the removal of Warren Hills Dam in Washington, NJ and partnered with the American Littoral Society to install a fish ladder at the Old Mill Pond Dam in Spring Lake Heights, NJ, which allows migratory fish to scale the dam and access spawning grounds that had been blocked-off for over 100 years.
We implemented a variety of measures that helped Lake Hopatcong, New Jersey's largest lake, mitigate harmful algal blooms (HABs). We applied a clay-based nutrient inactivating technology called Phoslock, which was the largest Phoslock treatment to occur in the Northeastern US. This treatment along with HAB prevention measures like the installation of biochar bags, nanobubble aeration systems, and floating wetland islands proved successful in mitigating HABs and improving overall water quality in 2020. And to top it all off, The Washington Post was awarded a Pulitzer Prize for its explanatory reporting on a novel climate change story featuring Lake Hopatcong and our lake management work.
We completed a shoreline restoration project at The Dunes at Shoal Harbor, a coastal residential community along the Jersey Shore that was severely impacted by Hurricane Sandy. In Linden’s Tremley Point neighborhood - another New Jersey community ravaged by Hurricane Sandy - we completed a green infrastructure and floodplain restoration project, the first restoration project to ever be implemented on NJDEP Blue Acres-acquired property. We transformed a densely developed, flood-prone, former industrial site in Bloomfield into a thriving public park with 4.2 acres of wetlands. Each of these three projects helped to restore valuable ecological functions and increase storm resiliency.
On World Habitat Day, the nonprofit, Schuylkill River Greenways, in partnership with Berks Nature, Bartram’s Garden, The Schuylkill Center for Environmental Education, Stroud Water Research Center, and Princeton Hydro, kicked-off a Water Quality Monitoring Project for the Schuylkill River. This project aims to document the current ecological health of the river and engage a diverse set of river users and residents. As part of the campaign, the team is recruiting “Community Scientists” to conduct Visual Monitoring Assessments. Additionally, the stakeholder team is implementing water quality sampling and monitoring throughout 2021 at locations along the main stem of the Schuylkill River.
This year, we added eight new full-time staff members and one intern with expertise and qualifications in a variety of fields, all of whom have a passion for water resource management and environmental stewardship. In March, we were thrilled to welcome Dr. Laura Craig to our team as the new Director of Natural Resources. She is an Aquatic Ecologist who has overseen 25 dam removals, co-founded the NJ Dam Removal Partnership, and has 10+ years of experience in river conservation and climate adaptation. Go here to learn about the career opportunities currently available with us.
The USACE Commanding General and 55th U.S. Army Chief of Engineers signed the Hudson River Habitat Restoration Ecosystem Restoration study, designating it as complete and making it eligible for congressional authorization. Princeton Hydro led the Integrated Feasibility Study and Environmental Assessment, which recommends three ecosystem restoration projects at sites along the river including Henry Hudson Park, Schodack Island Park, and Moodna Creek. The Hudson River Estuary is a significant habitat for fish, plants, and other wildlife, and this milestone marks progress toward the river’s return to a dynamic and self-regulating ecosystem. If constructed, these projects would restore almost 24 football-sized fields of wetlands in total.
The New Jersey Section of the American Water Resources Association honored Princeton Hydro with the “Excellence in Water Resources: Ecological Restoration Award” for the Linden Blue Acres Floodplain Restoration & Green Infrastructure project. This restored the ecological and floodplain function on former residential properties acquired by the NJDEP Blue Acres Program for the first time. The American Littoral Society and Princeton Hydro received the “Land Ethics Best Large-Scale Project Award” from Bowman’s Hill Wildflower Preserve for the work they did to restore the health and water quality of the Metedeconk River flowing through Ocean County Park in Lakewood, NJ. The Iowa Court and South Green Living Shoreline Project in Little Egg Harbor and Tuckerton, NJ, for which Princeton Hydro lead the sediment sampling/testing and hydrographic survey, received the “2020 Best Green Project Award” from Engineering News-Record.
During the Hudson River Estuary Program’s conference, Christiana Pollack, GISP, CFM presented on managing invasive Phragmites and restoring wetland habitats. And, at the Consortium for Climate Risk in the Urban Northeast, Christiana presented on a flood mitigation analysis project in a flood-prone Philadelphia community. As part of The American Sustainable Business Council’s “Clean Water is Good for Business” campaign, Marketing & Communications Manager, Dana Patterson, led a webinar, titled “Making the Business Case on Clean Water Issues to the Media.” At the 2020 Delaware Wetlands Conference, Senior Project Manager, Michael Rehman, presented a wetland restoration project that illustrates how a degraded urban area can be successfully rehabilitated. And, for a New York State Federation of Lake Associations webinar series, Senior Aquatic Ecologist, Chris Mikolajczyk, CLM, presented on a unique lake management initiative. And, our Director of Aquatics, Dr. Fred Lubnow, joined Rep. Debbie Mucarsel-Powell & other experts to discuss Harmful Algal Blooms at a virtual #ProtectCleanWater Town Hall hosted by the National Wildlife Federation Action Fund.
Our staff are repeatedly striving for personal growth and continue to amaze us. North American Lake Management Society chose Chris L. Mikolajczyk, CLM, Senior Aquatic Ecologist as the next President of the Board of Directors. Senior Ecologist, Michael Rehman, PWS, and Fluvial Geomorphologist, Paul Woodworth, became Certified Ecological Restoration Practitioners through the Society for Ecological Restoration. Emily Bjorhus and Robert George earned their Professional Wetland Scientist certification through the Society of Wetland Scientists program. In January, our Marketing & Communications Manager, Dana Patterson, received the Society of American Military Engineers New Jersey Post’s “Young Member Award” for her efforts in maintaining and advancing the objectives of the organization (pictured above). A national science journal published Environmental Scientist, Brittany Smith’s, graduate research study, which assessed “The Ecogeomorphic Evolution of Louisiana’s Wax Lake Delta.” Cory Speroff passed his Landscape Architecture exams and Andrew Simko earned his Professional Engineering license. And, Dr. Clay Emerson won our Earth Day Photo Contest with his incredible close-up of an Eastern Fence Lizard.
2020 was a particularly challenging year, but the Princeton Hydro family stood together. With offices spread across the Northeast and collaboration between offices on a daily basis, we were unknowingly prepared for the shift to remote work during an unexpected global pandemic. But, it took more than just working laptops and VPN connections to keep us going. Because of our staff’s motivation and dedication to serving our clients, we were able to not only keep our firm open, but we continued to grow our geographic and service reach.
Thank you for supporting Princeton Hydro and sharing our stories. We truly appreciate each and every one of our clients, partners, and friends. Cheers to a fruitful 2021 and beyond!
Welcome to the latest edition of our Client Spotlight Blog Series! Each spotlight provides an inside look at our collaboration, teamwork, and accomplishments with a specific client. We value our client relationships and pride ourselves on forming strong ties with organizations that share our values of creating a better future for people and our planet.
The Musconetcong Watershed Association (MWA) is an independent, non-profit organization dedicated to protecting and improving the quality of the Musconetcong River and its watershed, including its natural and cultural resources. Members of the organization are part of a network of individuals, families, and companies that care about the Musconetcong River and its watershed, and are dedicated to improving the watershed resources through public education and awareness programs, river water quality monitoring, promotion of sustainable land management practices, and community involvement.
Princeton Hydro has been working with MWA in the areas of river restoration, dam removal, and engineering consulting since 2003. To develop this Client Spotlight, we collaborated with MWA's Executive Director Cindy Joerger and Communications Coordinator Karen Doerfer:
A: As a watershed association, we focus on a specific place. This includes the Musconetcong River, a National Wild and Scenic River, as well as the area’s cultural, historical, recreational, and natural resources. We take a watershed focus, seeking to monitor the river and upstream areas to ensure it maintains good water quality.
A: MWA values community. Our membership is mostly grassroots, including residents, riverfront landowners, farmers, and local businesses. We value the long-term community of people who have helped form the organization, improve the river, and protect the scenic and historic resources that make our watershed unique.
A: Princeton Hydro has helped MWA with dam removal projects since the very first one, the Gruendyke Mill Dam, which was an obsolete dam on the border of Hackettstown and Mount Olive. Since then, Princeton Hydro has helped with four other dam removal projects and is currently assisting in the removal and restoration of the Beatty’s Mill Dam in Hackettstown, providing engineering plans and project management support.
The dam removals in the lower Musconetcong River have created a free-flowing passage to the Delaware River, and the removal of the Hughesville Dam welcomed the return of American shad less than a year after its removal.
A: Princeton Hydro has provided MWA with dam removal services on the Musconetcong River, most notably, the removal of Hughesville Dam, which brought Secretary of the Interior, Sally Jewell, out for its notching. Princeton Hydro has also helped us with the engineering and design for the Musconetcong Island Park Project, which involves the demolition of a building in a Historic District and the replacement of new, safer stairs.
A: The Hughesville Dam removal saw many successes and a few challenges we had to overcome as a team. After the initial removal and restoration, we worked together on another streambank restoration project to further stabilize the streambank near the dam removal site. This dam removal restored over 5 miles of free-flowing river to the Delaware River and will help lay the groundwork for the Warren Glen Dam removal, which is the largest dam on the Musconetcong River.
A: MWA is still working to restore the Asbury Mill, which we plan to use as an educational and eco-tourism hub for the community, as well as a much-needed office space for our growing staff.
A: Working for such a small organization, it is easier and more gratifying to see the impact it's making. Our staff gets to see a lot of projects from start to finish, so it’s rewarding to be able to have your stamp on something you watched grow from its inception to conclusion.
A: In the upper watershed, we are hoping that Princeton Hydro, in concert with others, can continue to help guide improvements to the water quality of Lake Hopatcong. The lake acts as our headwaters and is the largest in New Jersey. Last year, it suffered a serious issue with Harmful Algal Blooms.
…
Over the last two decades, we've restored many miles of rivers, improved water quality in hundreds of ponds and lakes, and enhanced thousands of acres of ecosystems in the Mid-Atlantic and New England regions. In 2019, we had our best year yet. As we reflect back on 2019 and set our sights on 2020, we have many successes to celebrate:
The century-old Columbia Dam was removed and fish passage was restored on the 42-mile long Paulins Kill river, an important tributary to the Delaware River in northwestern New Jersey. On Earth Day 2019, just two months after the river finally flowed free, we were thrilled to discover the return of American shad upstream for the first time in over 100 years.
Our team completed a feasibility study for the U.S. Army Corps of Engineers (USACE), which identified and conceptualized restoration opportunities at six key sites. For this Hudson River Habitat Restoration Integrated Feasibility Study and Environmental Assessment, Princeton Hydro collected and analyzed data, reviewed existing conditions, and drafted conceptual restoration designs. Our final report was just highlighted by USACE at the 2019 Planning Community of Practice (PCoP) national conference at the Kansas City District as an example of a successfully implemented Ecosystem Restoration Planning Center of Expertise (ECO-PCX) project.
After a record-breaking number of HABs broke out in lakes across the region, our Aquatics Team was called upon for their expertise and insights into why the outbreak was happening, what could be done to treat it, and what preventative actions will lessen the likelihood of future outbreaks. In addition to being featured in various regional news outlets covering the HABs topic, Princeton Hydro experts were featured in the New York Times and the Washington Post for their leadership at the largest lake in New Jersey, Lake Hopatcong. (Photo credit: Washington Post)
From galas to environmental conferences and river restoration tours to college courses, the Princeton Hydro team participated in more than 50 events throughout 2019. Dr. Clay Emerson, PE taught a Green Infrastructure Stormwater Management Course at Montclair University. Kelsey Mattison, Marketing Coordinator, presented at the 3rd Annual New Jersey Watershed Conference. And, at the New Jersey Land Conservation Rally, we had three presentations on citizen science, marketing strategy, and lake stewardship. Various team members rolled up their sleeves to volunteer to plant trees at Exton Park on Arbor Day, build a rain garden in Clawson Park, and restore eroding shoreline in Point Pleasant. Stayed tuned for more in 2020!
Mercer County’s John A. Roebling Memorial Park is home to the northernmost freshwater tidal marsh on the Delaware River, Abbott Marshland, an area containing valuable habitat for many rare species. Unfortunately, the area has experienced a significant amount of loss and degradation, partially due to the introduction of the invasive Phragmites australis. The Princeton Hydro team proudly removed this invasive species and is restoring the marsh to enhance plant diversity, wildlife habitat, and water quality.
To prevent further erosion at the Slade Dale Sanctuary in Point Pleasant, dozens of volunteers helped stabilize the shoreline using recycled Christmas trees, a technique never been done before in New Jersey. The 13-acre Slade Dale Sanctuary is an important part of the local ecosystem and much work is being done there to restore the marsh and enhance the ecological function and integrity of the preserve. Princeton Hydro developed a conceptual and engineering design using living shoreline features, including tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion.
The Friends of the Presumpscot River awarded Laura Wildman, P.E., with its “Chief Polin Award” for her accomplishments and efforts in bringing life back to the Presumpscot River and rivers across the nation. The New Jersey Highlands Coalition honored Founding Principal Dr. Stephen Souza with a Lifetime Achievement Award, touting his dedication to preserving and protecting New Jersey’s watersheds and natural resources. And, our Pin Oak Forest and Wetland Restoration project earned the “Land Ethics Award of Merit” from Bowman’s Hill Wildflower Preserve for its remarkable restoration achievements.
Along the Third River and Spring Brook, two freshwater tributaries of the Passaic River, a former industrial site that is highly-disturbed and flood-prone is being transformed into a thriving public park. The team broke ground on this important ecological restoration and urban wetland creation project in March and the restoration work continues. Princeton Hydro is serving as the ecological engineer to Bloomfield Township providing a variety of services and expertise.
As part of the expansion of our growing business, Princeton Hydro added 12 team members with expertise and qualifications in a variety of fields. In July, we announced a new executive position in the firm, Director of Operations. We also created an internal Human Resources Department and hired Samara McAuliffe as Employee Relations Manager. Princeton Hydro has grown from a small, four-person idea operating out of a living room to a 65+ person qualified Small Business with six office locations in the Northeast region.
We’re moving on up! In 2019, we moved our D.C. Regional Office down the road from Annapolis, MD to Bowie, MD expanding into a larger office space to accommodate our staff growth and providing opportunity for more growth in the region. And, in late 2019, through our strategic partnership with Merestone Consulting, we opened a sixth office in Wilmington, Delaware. Stay tuned for more information!
Thank you for supporting Princeton Hydro and sharing our stories. We truly appreciate each and every one of our clients and partners. Cheers to a fruitful 2020 and beyond!

To prevent further erosion at the Slade Dale Sanctuary in Point Pleasant, dozens of volunteers helped stabilize the shoreline using a technique that has never been done before in New Jersey. On Saturday, American Littoral Society, in partnership with Princeton Hydro, Borough of Point Pleasant, New Jersey Nature Conservancy, New Jersey Corporate Wetlands Restoration Partnership, and the Point Pleasant Rotary Club, organized dozens of volunteers to restore the shoreline and prevent further erosion at the Slade Dale Sanctuary using recycled Christmas trees.
As one of only a few areas of open space left in Point Pleasant, the 13-acre Slade Dale Sanctuary is an important part of the local ecosystem and is home to a number of unique animals and plants. This waterfront preserve along the North Branch Beaver Dam Creek is predominantly tidal marsh, which provides habitat for various birds, including osprey, as well as passive recreation opportunities for the community.
Unfortunately, the Slade Dale Sanctuary is disappearing. Since 1930, the shoreline of Slade Dale Sanctuary has retreated approximately 300 feet, equal to the length of a football field, and the channels into the marsh have increased in number and size, according to a study we conducted on behalf of American Littoral Society, for which we provide engineering and natural resources management consulting services.
In order to stabilize the shoreline, restore the marsh, and enhance the ecological function and integrity of the preserve, Princeton Hydro developed a conceptual and engineering design using living shoreline features to enhance ecological value and reduce erosion. The final conceptual plan for restoration uses tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion along the coast.
To implement this vision and begin building back marsh, the project team is constructing several Christmas tree breakwaters and Christmas tree vanes that mimic naturally occurring debris structures in tidal systems and enhance habitat opportunity and shelter for aquatic life. Volunteers came together on Saturday, May 11 to help with the construction. The Mayor of Point Pleasant Robert A. Sabosik also attended the event, "The Barnegat Bay is an attribute that we all enjoy, and it's something we have to protect."
After the 2018 holiday season, the Good Sheppard Lutheran Church in Point Pleasant provided space to collect and store donated Christmas trees, which were then moved to the marsh a few days before the event. On the day of the event, recycled Christmas trees were transported from their staged locations on the marsh to the breakwater sections that were previously installed in the water. To transport them across the water to the pilings, volunteers used two methods: by walking a skiff boat loaded with trees through the water to the pilings or by forming assembly line from the shore to pilings to guide floating trees through the water (check out the album below!). Then, they stuffed the Christmas trees between the pilings, securely tied them down, and staked Christmas trees directly into the creek bottom. For extra assurance, the placed and tied heavy bags of used oyster shells on top of the tree line. Oyster shells were donated by local Monmouth County restaurants in an effort to reduce waste streams.
"We really enjoyed participating in this event with American Littoral Society and so many wonderful volunteers,” Christiana L. Pollack, GISP, CFM, Princeton Hydro's Project Manager for this restoration effort. “It is so wonderful to see this project coming to fruition. We’re so proud of our partnership with American Littoral Society and our combined efforts to revitalize and rehabilitate our precious coastal habitats.”
