This long-anticipated project, spearheaded by the Farmington River Watershed Association (FRWA), is a major milestone in the restoration of the Farmington River. The full removal and restoration effort, which began on September 8, is expected to be completed within two weeks and will reconnect 30 miles of critical upstream habitat. The effort is the result of a robust collaboration among project partners, following years of persistence and careful planning to turn a long-standing vision for the Farmington River into reality. Under the leadership of FRWA, the project partners include Miss Porter's School, the current dam owner; Princeton Hydro, providing engineering, design and project oversight; RiverLogic Solutions; CTDEEP Fisheries; and the Town of Farmington. Together, these partners are advancing ecological restoration, community safety, and recreation access along one of New England's most celebrated rivers. Photo taken September 10 by Princeton Hydro Director of River Restoration & Resilience Christiana Pollack, CERP, CFM, GISP Restoring Natural Function & Reconnecting Habitat The Farmington River, a designated "Partnership Wild & Scenic River," flows for nearly 47 miles along its main stem in northwest Connecticut, with major tributaries extending into southwest Massachusetts. It's longest route, originating from the West Branch, stretches 80.4 miles, making it the longest tributary of the Connecticut River. Its watershed spans more than 600 square miles, providing critical drinking water to hundreds of thousands of people, supporting a world-class trout fishery, and serving as a vital habitat for a variety of resident and migratory species. Nearly 79 miles of the river are federally protected for their outstanding natural, cultural, and recreational values. The Winchell-Smith Dam, a 200-foot-wide, 4-foot-high, low-head timber crib structure, dates back to the early 1600s and may have been the first gristmill ever built on the Farmington River. The dam had long ceased to serve a functional purpose but continued to impede the river's natural process, blocked access for migratory fish, created localized erosion and scour, presented an obstacle for paddlers and anglers, and posed as a safety hazard.

Most significantly, it reopens 30 miles of historic spawning habitat for species such as American shad, alewife, blueback herring, sea lamprey, and American eel, and provides unobstructed access to the upper reaches of the river and its tributaries. The restored river channel will support healthier fish populations, stabilize riverbanks, reestablish important wildlife habitat, and improve water quality. Additionally, the project enhances public safety by eliminating a hazardous low-head dam and expands opportunities for nature-based recreation along this cherished waterway.

Funding constraints and the dam's continued deterioration ultimately made full removal the only viable option. With funding support from CTDEEP Fisheries, the effort to fully remove Winchell-Smith Dam was finally able to advance. Princeton Hydro provided comprehensive engineering services, including site investigation and geomorphic inspection, wetland delineation, hydrologic assessment and hydraulic modeling, permitting, and construction oversight. The removal of the Winchell-Smith Dam is part of a larger restoration plan initiated by FRWA and Princeton Hydro, which included the removal of the Spoonville Dam.

Timbers from the structure are being preserved and repurposed for educational objectives, honoring the site's industrial legacy while celebrating its ecological renewal. Rocks and boulders from the dam will also be used to restore the river location, constructing a riffle-like condition in the riverbed. The project also aims to foster the next generation of environmental stewards by engaging the students at Miss Porter's School and local public schools. Throughout the process, students are participating in hands-on activities that deepen their understanding of river restoration and introduce them to STEM subjects like engineering and ecology.

Welcome to our Partner Spotlight blog series, where we highlight the meaningful collaborations and shared successes Princeton Hydro enjoys with our valued partners. Today, we’re shining the spotlight on Save Barnegat Bay, a nonprofit rooted deeply in environmental advocacy and stewardship, dedicated to safeguarding Barnegat Bay.
Fed by freshwater inputs from rivers, creeks, and streams, and saltwater from the Atlantic Ocean, Barnegat Bay is a unique estuary stretching approximately 42 miles from Bay Head to Long Beach Island and the Little Egg Harbor inlet. Barnegat Bay is the largest body of water in New Jersey and one of the region’s most valuable natural resources.
Save Barnegat Bay, founded in 1971 by neighbors concerned about the future of their local waterways, has grown into a highly respected, effective, and influential voice for environmental protection throughout the state. Through advocacy, education, restoration, and community engagement, the organization is leading the charge to preserve the Barnegat Bay ecosystem and the wildlife and communities that call it home.
For this Partner Spotlight, we spoke with Britta Forsberg, Executive Director of Save Barnegat Bay, who brings decades of personal and professional commitment to protecting this vital resource.
Let’s jump in!
“What truly sets Save Barnegat Bay apart is our hyper-local approach. We’re not a Washington, D.C.-based environmental group, we’re right here in the Barnegat Bay Watershed, working directly with the communities we serve. For 54 years, we’ve remained a steady and effective environmental voice, and we’ve achieved meaningful, lasting impacts through persistence, collaboration, and grassroots engagement.”
In the video below, Britta shares more about the guiding vision behind Save Barnegat Bay’s work and what continues to fuel the organization’s success:
“Save Barnegat Bay’s work spans decades and addresses a wide range of threats to the watershed, from nutrient pollution to legacy contamination. One of our most impactful successes is the passage of the New Jersey Fertilizer Law, which we wrote and lobbied for. It remains the strictest fertilizer content law in the country. This effort began with local ordinances, but we quickly realized a patchwork of municipal laws wasn’t effective. So, we pursued statewide legislation to reduce nitrogen pollution, a major stressor for Barnegat Bay’s ecological health. This law has helped prevent millions of tons of nitrogen from entering New Jersey’s waterways.
Another critical focus for us is environmental justice and accountability. We’re currently challenging a controversial settlement related to the Ciba-Geigy Superfund Site in Toms River. This site has a painful history: decades ago, a chemical plant discharged toxic waste into rivers, groundwater, and even the Atlantic Ocean, resulting in significant health impacts, including a well-documented childhood cancer cluster. While criminal charges and civil suits were eventually brought, we’re now fighting for appropriate restitution. We believe the NJDEP’s current settlement with the site’s owner, BASF, the world’s largest chemical company, lacks transparency and fails to account for the full environmental damage. We’ve filed an appeal and are advocating for a more just and science-based resolution that considers the lasting damage to 1,200 acres of land, the groundwater, wetlands, river, bay, and ocean.
We’re also proud to have played a leading role in the closure of the Oyster Creek Nuclear Generating Station, once the oldest operating nuclear plant in the country. The plant’s design used Barnegat Bay water to cool its reactors, then discharged superheated water back into the estuary, devastating marine life daily. We believe Save Barnegat Bay is the only grassroots environmental organization in the U.S. to successfully close a nuclear plant not on the basis of nuclear energy itself, but on its local ecological impacts.
These are just a few examples of the many efforts Save Barnegat Bay has led or supported over the years. From legislative advocacy to grassroots mobilization, our work is broad and ongoing. What unites it all is our deep commitment to protecting the Bay and ensuring its health for generations to come.”
“Barnegat Bay relies on a delicate and often overlooked network of 58 named rivers, creeks, and streams. Many of these freshwater sources originate in the Pine Barrens, winding through Ocean County and parts of Monmouth County before reaching the Bay. They are the lifeblood of the estuary, delivering freshwater that supports the Bay’s health, biodiversity, and overall ecological function.
Our “Rivers, Creeks, and Streams” campaign was created to inspire and connect people with their local waterways and take part in their protection. Whether it's through cleanup activities, water sampling, or making simple, eco-friendly changes at home, we believe small actions can collectively have a big impact.
Thanks to the generosity of local businesses, we've been able to acquire a fleet of canoes and kayaks to get people, including elected officials and community leaders, directly out on the water. This hands-on approach helps participants build a personal relationship with their local water resources, see firsthand the challenges and opportunities for improvement, and feel empowered to help. It’s one thing to talk about water quality in a meeting room, it’s another to experience it on the water, paddle in hand.”
In the video clip below, Britta shares more about this unique initiative:
“Over the years, we’ve collaborated with Princeton Hydro on a wide range of impactful projects. We've worked with many members of their team, including Dr. Steve Souza; Dr. Fred Lubnow; Geoffrey Goll, P.E.; and Mark Gallagher, just to name a few. Our work together has spanned everything from technical restoration projects to public education initiatives. In fact, we’ve probably partnered with a good portion of their staff at some point on various critical initiatives across the watershed.”
In the video clip below, Britta highlights two collaborative projects that stand out as major wins, successfully protecting sensitive habitats while navigating the priorities of various stakeholders:
Britta continues: “We’re also partnering with Princeton Hydro to take a proactive approach to water quality management in coastal towns throughout the Barnegat Bay Watershed. Specifically, we’ve been supporting Point Pleasant Beach and Bay Head in developing comprehensive lake and watershed management plans. There are three coastal lakes in Point Pleasant and one in Bay Head, and these proactive planning efforts have been incredibly valuable for those communities.
Honestly, I could go on and on. We’ve worked with Princeton Hydro on so many important projects together; it’s a true partnership.”
“There are so many ways to get involved. At Save Barnegat Bay, we encourage people to contribute and participate in whatever way works best for them—time, treasure, or talent. Nearly everything we offer is free and open to the public, from hands-on workshops like rain barrel construction to science-based programs like eelgrass planting and clinging jellyfish monitoring to volunteer initiatives like shoreline clean-ups. We’re not a membership-based organization, which means there’s no barrier to participation. You can simply show up and engage in whatever way feels right to you.
Britta leaves us with a few inspiring words about the power of big ideas, and a reminder to look beyond the everyday and believe in what’s possible:
A heartfelt thank you to Britta Forsberg for her time, passion, and leadership, and for sharing the inspiring story of Save Barnegat Bay. Her dedication to community-driven stewardship and environmental advocacy reflects the profound impact that local action can have on protecting vital natural resources on a wide-reaching scale.

Ever wondered how scientists measure lake water clarity? One of the simplest and most enduring tools for the job is the Secchi disk.
Long before it became a formal scientific tool, sailors and scientists were already using simple methods to estimate water clarity, like lowering white objects into the water to gauge visibility and depth. In 1865, Italian astronomer Father Pietro Angelo Secchi built on these early techniques by developing a uniform white disk and standardized utilization method. His published findings helped establish the Secchi disk as a practical tool for water quality assessment.
The design was later improved by George C. Whipple, who added alternating black and white quadrants to enhance visibility. Today, this version of the Secchi disk remains a staple in the field kits of aquatic scientists and limnologists worldwide.
As part of our Field Notes blog series, which spotlights essential tools and techniques used by our team, Senior Aquatics Manager Christopher L. Mikolajczyk, CLM, demonstrates how to properly use a Secchi disk and explains how this simple method helps inform lake and pond management strategies. Watch now:
As Chris explains in the video, water clarity is a key indicator of overall lake health, and monitoring it provides valuable insight into the condition and functioning of aquatic ecosystems. Regular monitoring helps lake managers understand whether conditions are within a healthy range, identify potential indicators of future algal blooms, and make informed decisions to maintain ecological balance.
Interested in getting involved? With a few simple materials, you can build your own Secchi disk and participate in the Secchi Dip-In, a community science initiative where volunteers measure and report water clarity data. While the Dip-In is traditionally celebrated in July during Lakes Appreciation Month, data collection is welcomed and encouraged year-round.
Chris has dedicated over 25 years to advancing the science and practice of aquatic ecology and water resource management. His expertise spans the management, oversight, and coordination of projects in three key areas: aquatic resource restoration and management, aquatic ecosystem sampling and investigations, and stormwater quality modeling and management. Chris has an Associate's, Bachelor's, and Master's degree in Water and Watershed Resource Management. In addition to his work with Princeton Hydro, Chris currently serves as the President-Elect of the Colorado Lake and Reservoir Management Association’s 2025 Board of Directors and has also served as President of North American Lake Management Society. These leadership roles highlight his dedication to advancing aquatic resource conservation.
Each July, we take time to reflect on the beauty, value, and importance of lakes during Lakes Appreciation Month. Since 1998, this national initiative founded by the North American Lake Management Society (NALMS) has encouraged communities to get outside, engage with their local waterbodies, and take action to protect them.
This year, we’re sharing four simple and meaningful ways to celebrate. If you're a lake regular or you're just starting to dip your toes into lake stewardship, you'll find something valuable here!
There’s no better way to appreciate your local lake than by exploring it up close. Take a morning paddle, enjoy a peaceful shoreline walk, or head out with a fishing rod and a friend. Lakes offer the perfect setting for adventure, reflection, and connection with nature. Whether it’s your first visit or your hundredth, there’s always something new to discover and appreciate at your local lake.
And thanks to digital tools, exploration doesn’t stop at the water’s edge. For example, in Pennsylvania, the Bucks County Conservation District, in collaboration with Bucks County Planning Commission and Princeton Hydro, recently launched an interactive ArcGIS StoryMap showcasing the Lake Luxembourg watershed and Conservation Pool Restoration Project. This interactive tool lets you experience the lake’s ecology in a whole new way. Take a deeper dive—without getting your feet wet—and check out the StoryMap here.
Join lake lovers across North America for the annual Secchi Dip-In, a citizen science event where volunteers collect water clarity data using a simple Secchi disk. This collective initiative helps monitor lake health over time and contributes valuable data to local lake managers and the broader scientific community.
Getting involved is simple—grab a Secchi disk (they're easy to make), take a turbidity reading, and submit your data online using the Secchi Dip-in database. Need guidance on how to use a Secchi disk? Check out our instructional video for a step-by-step walkthrough:
Get creative and let your appreciation for lakes shine. Try your hand at Lakes Appreciation Month Bingo, make a short video, write a lakeside haiku, or paint a scene from your favorite shoreline. When you express your love for lakes through art, you can also inspire others to connect with and care for their local lakes.
You can also participate in the NALMS “Show Your Lakes Appreciation” Challenge. While you’re out enjoying your favorite lake, snap a #lakeselfie, capture a scenic sunset, or photograph your pet mid-paddle. Post your photo on your favorite social media platform with the hashtag #LakesAppreciation and include the name of the lake in your caption for a chance to win prizes and be featured online. The contest runs all month long!
Here's a winning entry from last year—a joyful shot of “Jo Jo the dog kayaking on Lake Michigan.”
Looking to make a tangible impact? Volunteer for a local lake cleanup, support your watershed association, or become a lake steward helping to monitor your lake's water quality, remove invasive species, and more! Even taking small actions in your own backyard, like reducing fertilizer use or installing a rain garden, can make a big difference for water quality.
Princeton Hydro has had the privilege of partnering with lake associations, municipalities, and nonprofit organizations across the country on a wide range of lake restoration and stewardship efforts. These partnerships show what’s possible when communities come together to invest in their lakes. Read about our recent collaboration with Smith Mountain Lake in Virginia.
Whether you’re picking up trash, attending a public meeting, or just learning more about lake science, your involvement matters.
The Borough of Harveys Lake, in partnership with Princeton Hydro, launched a new interactive ArcGIS StoryMap that chronicles the community’s long-standing commitment to water quality and showcases a recently completed pilot project aimed at reducing stormwater nutrient pollution.

Interactive features, such as zoomable maps, clickable pins, and site-specific details, offer an intuitive, user-friendly experience.
More than just a visualization tool, the StoryMap serves as a community-education and engagement platform. It highlights how local stormwater management strategies, like those implemented at Harveys Lake, can drive positive, region-wide change, underscoring the vital role of place-based solutions in improving watershed health across the Chesapeake Bay region.
The StoryMap begins with an exploration of the Chesapeake Bay Watershed—one of the most ecologically and economically significant estuaries in the United States. This region faces complex environmental challenges, including nutrient pollution, habitat loss, and climate change impacts. Over the past several decades, a wide range of stakeholders have engaged in coordinated restoration efforts to protect and improve water quality across the watershed.
Using interactive maps, expandable sections, and rich visuals, this introductory portion of the StoryMap places Harveys Lake in a broader regional context. It sets the stage for understanding how local action, such as nutrient reduction at Harveys Lake, plays a critical role in supporting the health of the entire Chesapeake Bay ecosystem.
The next section, “Harveys Lake: A Case Study,” highlights the Borough's ongoing dedication to protecting the lake and improving water quality through science-based solutions and collaborative efforts. The StoryMap provides:
The final section of the StoryMap dives into a 2025 pilot initiative that used biochar and EutroSORB® filter media to reduce dissolved phosphorus and total nitrogen from stormwater runoff. Organized into subsections—Project Information, Methodology, Results and Discussion, Pollinator Garden, and Future Implications—the StoryMap offers a detailed look at this innovative nutrient-reduction strategy and its potential for replication across the Chesapeake Bay watershed.
In addition to detailing the pilot project, this section also spotlights the creation of a native pollinator garden, planted using the spent biochar as fertilizer. This closed-loop approach not only reinforces the project’s long-term ecological value but also demonstrates how thoughtful design can deliver multiple environmental benefits while cultivating a vibrant community-oriented space that supports local biodiversity.
To extend the impact of this initiative, the StoryMap was provided to the Harveys Lake Borough Environmental Advisory Council (EAC) and is publicly accessible via the Borough’s website.

The New York State Federation of Lake Associations (NYSFOLA) 42nd Annual Conference was held on May 2 and 3 at the the Fort William Henry Hotel and Conference Center in Lake George. In the theme “Back to the Future: Old Lake Issues and New Solutions,” the event featured panel discussions, workshops, networking opportunities, and an exhibitor hall. Princeton Hydro sponsored, exhibited and led two workshops: Chris Mikolajczyk, CLM, Senior Manager of Aquatics, presented “Old Lake Issues? The EPA National Lakes Assessment (2000s) and Funding New Experimental Solutions.” And, Dr. Fred Lubnow, Senior Technical Director of Ecological Services, presented “Internal Loading: Updated Solutions for an Old and Increasing Problem for Lakes.”
Earlier this month, lake advocates, environmental professionals, researchers, and community leaders gathered for the 42nd Annual New York State Federation of Lake Associations (NYSFOLA) Conference. Held at the Fort William Henry Hotel and Conference Center, overlooking beautiful Lake George, the event brought together individuals from across the region to reexamine longstanding lake and watershed challenges through the lens of innovation, collaboration, and science.
With this year’s theme, “Back to the Future: Old Lake Issues and New Solutions,” the conference emphasized how new policies, technologies, and strategies can be applied to address persistent water quality issues. The two-day program featured a robust lineup of educational sessions, workshops, an exhibitor hall, and networking opportunities, all designed to inspire fresh ideas and collective action.
The conference kicked-off with a keynote from Greg Michel, Executive Director of Onondaga Earth Corps, a youth and community development organization headquartered in Syracuse, New York that engages young adults in environmental service projects. Michel and his team inspired attendees with stories of empowering the next generation of conservationists while tackling real-world ecological needs.
As a proud sponsor, event exhibitor, and long-time member of NYSFOLA, Princeton Hydro led two educational workshops, both focused on bringing data-driven insights and practical funding strategies to lake communities.
Chris L. Mikolajczyk, CLM, Senior Manager of Aquatics shared insights from the most recent EPA’s National Lakes Assessment (NLA), which offers a statistically valid snapshot of lake health across the US. Using data from the NLA’s recurring five-year surveys, he illustrated how the findings help identify ecological conditions, long-term trends, and stressors impacting our lakes.
While the Clean Lakes Program (Section 314 of the Clean Water Act) once provided federal funding for in-lake restoration, it hasn’t been funded since 1995. Chris emphasized how large-scale assessments like the NLA can still play a crucial role in shaping effective lake management strategies and strengthening funding proposals. He spotlighted current funding opportunities from the New Jersey Highlands Council, the National Fish and Wildlife Foundation, and the U.S. Army Corps of Engineers Environmental Research and Development Center. Through real-world case studies, he illustrated how data-driven planning can translate into on-the-ground results for lake restoration and protection.
Dr. Fred Lubnow, Senior Technical Director of Ecological Services, tackled internal phosphorus loading—a growing concern for lakes already struggling with nutrient enrichment and harmful algal blooms (HABs). Unlike external sources of pollution, internal loading arises from within the lake itself, particularly in sediment layers that continue to release nutrients long after the original source has been addressed.
Fred provided detailed case studies from lakes across the Northeast and Mid-Atlantic, including Lake Mohawk and Lake Hopatcong in New Jersey, Harveys Lake in Pennsylvania, and Smith Mountain Lake in Virginia. He demonstrated how targeted in-lake and watershed strategies, when backed by proper assessment and data, can successfully reduce internal phosphorus levels and improve long-term lake health.
Thank you to NYSFOLA for another outstanding conference and the opportunity to support the mission of protecting New York’s lakes. Princeton Hydro is proud to be part of this dynamic community advancing innovative, science-based solutions. We enjoyed the engaging conversations, insightful presentations, and opportunities to collaborate with lake professionals from across the region — and we had a blast at trivia night!
On April 9, experts and stakeholders from across the country gathered virtually for the New Jersey Department of Environmental Protection’s (NJDEP) 6th Annual Harmful Algal Bloom (HAB) Summit. Held via Microsoft Teams and free to attend, this year’s summit embraced the theme “Kicking the HAB-it Together: Collaborating to Get Ahead of HABs”—a fitting reflection of the event’s focus on moving away from crisis-driven responses and toward proactive, long-term solutions for managing HABs.
The summit brought together a diverse audience of local, state, and federal government representatives, environmental commissions, watershed associations, nonprofits, academic researchers, lake management professionals, and community members united by a shared goal: to better understand, prevent, and manage the impacts of HABs. With presentations spanning public health, policy, science, and on-the-ground solutions, the program set the stage for a day of insightful discussion and knowledge-sharing.
The day kicked off with opening remarks and presentations from NJDEP representatives and the Montgomery Township Health Department, who provided updates on state-level HAB response efforts and local public health perspectives. The morning session also featured a technical keynote address from Dr. Wayne Carmichael, Professor Emeritus at Wright State University and a nationally recognized pioneer in HAB research. Dr. Carmichael offered a comprehensive national overview of the current HAB landscape, emerging threats, and the evolving science behind bloom detection, health risk assessment, and mitigation strategies. His presentation underscored the importance of cross-sector collaboration in tackling this growing environmental challenge.
In the afternoon, the focus shifted to collaboration and preparedness. A panel discussion titled “Getting Ahead of the Crisis: Prevention vs. Response” included a range of voices, including NJDEP leadership, municipal representatives, and advocacy groups like The Watershed Institute. Panelists discussed how coordinated efforts, regulatory tools, and community engagement can help prevent the conditions that lead to HABs, rather than merely responding after blooms occur.
The final portion of the summit highlighted innovative management strategies. Presentations covered topics like choosing practical solutions for HABs and restoration case studies. Princeton Hydro’s own Pat Rose, Aquatics Project Manager and Environmental Scientist, was among the expert speakers. Pat presented on a cutting-edge research and development initiative funded by the U.S. Army Corps of Engineers' Engineer Research and Development Center (ERDC). His talk explored both proactive and reactive treatment strategies designed to control near-shore HABs at Lake Hopatcong, New Jersey's largest lake, in a cost-effective and sustainable manner.
If you weren’t able to attend the summit live, don’t worry—you can now watch the full recording on the NJDEP YouTube channel:
HABs are rapid, large overgrowths of cyanobacteria. Cyanobacteria, also known as blue-green algae, aren’t actually algae, they are prokaryotes, single-celled aquatic organisms that are closely related to bacteria and can photosynthesize like algae. These microorganisms are a natural part of aquatic ecosystems, but, under the right conditions (e.g., heavy rains followed by hot, sunny days), these organisms can rapidly increase to form HABs. Climate change is leading to more frequent, more intense rainstorms that drive run-off pollutants into waterways, coupled with more hot days that increase the water temperature, creating the ideal environment for HABs to proliferate. In recent years, HABs have begun to appear in more places, earlier in the summer.
The New Jersey Governor’s HABs Initiative was launched in 2019 after lakes throughout NJ (and the entire Continental U.S.) suffered from HAB outbreaks, which caused local and county health agencies to close off all beaches and issue advisories. These unprecedented conditions had significant negative impacts on lake-related ecological, recreational, and economic resources. The Governor’s initiative designated $13 million in funding to local communities for HABs reduction/prevention; established the HABs expert team, which includes Princeton Hydro Senior Technical Director, Ecological Services Dr. Fred Lubnow; and coordinated annual HABs summits in order to encourage continued community education and discussion.
