Welcome to the latest edition of our Client Spotlight blog series, which provides an inside look at our collaboration, teamwork, and accomplishments with one of our client partners.
In this special edition, we’re shining the spotlight on the Town of Mina and Findley Lake Watershed Foundation (FLWF), two organizations working closely together to protect and preserve Findley Lake in Chautauqua County, New York. This charming 300-acre lake is a cherished focal point for recreation, tourism, and community pride, and safeguarding it is a shared responsibility. The Town of Mina and FLWF, a volunteer-led nonprofit, have built a strong partnership dedicated to maintaining the lake’s health and ensuring its long-term sustainability.
We kicked-off the conversation with a question for Rebecca:
Rebecca continues: “As part of our 2024 Comprehensive Plan, the Town of Mina identified four core community values that guide our decision-making, with our top priority being Findley Lake!
The lake is the heart of our community. Ensuring it remains clean, beautiful, and accessible for recreation and overall enjoyment is essential to our identity. That’s why we work so closely with FLWF. During the comprehensive planning process, FLWF developed a Lake Management Plan, which now guides our environmental efforts.
Our second core value is economic development. Findley Lake is experiencing an exciting period of growth, with several initiatives underway, including a new warehouse distribution center, growing retail presence, and revitalization in the downtown area. It’s truly a renaissance moment for our community.
Third, we’re deeply committed to preserving and enhancing our community character. We value our rural lifestyle and are working to improve it with expanded trails, new boardwalks, and safer, more accessible green spaces for all to enjoy. And, our fourth core value centers on strengthening local government, becoming more efficient, effective, and responsive to the needs of our residents. We want people to feel heard, supported, and engaged in the future of our town.”
“FLWF was established in 2002, but our roots go back much further. Before that, our work was carried out by the Findley Lake Property Owners Association, which formed in the late 1940s after the lake was no longer needed as a power source for milling operations.
At that time, the lake and dam were donated by Larry Schwartz to a group of local, stewardship-minded residents. That group did the best they could with limited resources and knowledge. But as science, lake management practices, and environmental awareness progressed, so did our approach.
By transitioning to a 501(c)(3) nonprofit in 2002, we were able to access grant funding and expand our work significantly. Since then, we’ve purchased weed harvesters, partnered with Princeton Hydro for lake studies, and supported major infrastructure projects like the new sewer system currently in development to address septic-related pollution.
We’ve also taken steps to reduce streambank erosion and manage phosphorus loading that affects lake oxygen levels. Our board is strong and diverse—we have dedicated members with the expertise needed to keep moving the organization and the lake forward. At our core, FLWF is committed to maintaining, enhancing, and improving the quality of Findley Lake and its watershed through science-based action and collaboration.”
Rebecca continues: “We’ve made significant strides in advancing the health of our local environment, thanks in part to support from the New York State Department of Environmental Conservation (DEC). We’ve completed three DEC-funded studies that are guiding our next steps.
One study focused on culverts throughout the watershed with the goal of improving water flow and reducing flood risk. Every culvert was assessed to identify those that need repair or replacement. Another study analyzed stormwater runoff, identifying ten key inflow areas to Findley Lake where erosion and sedimentation pose potential threats. Each site was evaluated and prioritized, and we’ve since secured a DEC grant to address the highest-priority site. And, the third study explored in-lake nutrient control strategies, which laid the groundwork for our current partnership with Princeton Hydro on nutrient management efforts.
Beyond lake-focused work, we’re also committed to enhancing community access to nature. We’ve received support from Chautauqua County for efforts that will benefit both the environment and quality of life for residents and visitors alike.”
“We first partnered with Princeton Hydro a few years ago when our board recognized the need for expert guidance on lake management. While we have a strong, professional board, we lacked the specialized knowledge in lake ecology and water quality science to move forward confidently with major decisions.
After researching several firms, we chose to bring Princeton Hydro on board to help us better understand nutrient dynamics in the lake. One of our key concerns was the persistent late-summer algae blooms, which we later learned were linked to phosphorus being released from the lake’s sediments.
Princeton Hydro conducted an in-lake nutrient study that clearly explained this internal loading process and helped us chart a path forward. Building on that work, we’re now working with the Princeton Hydro team on a bathymetric and sediment analysis to guide our next step, which will be to install an aeration system to reduce phosphorus release and improve water quality.
Princeton Hydro’s expertise has been instrumental in making complex science understandable and actionable, which has helped us take meaningful steps toward restoring the health of Findley Lake.”
Following Rebecca’s remarks, Ed adds: “I’d just like to echo what Rebecca said—the Princeton Hydro team we worked with this Spring was truly a pleasure to collaborate with. Their depth of knowledge was impressive, but just as important was their ability to communicate complex concepts in a way that was clear and easy for our board to understand. That kind of approachability made a big difference. It was a great experience working with them.”
“We’re always grateful for donations, they fuel much of what we do. But beyond financial support, one of the most valuable ways people can contribute is by sharing their experiences and ideas.
There are countless lakes and watershed organizations out there facing similar challenges, and many have come up with innovative, cost-effective solutions. We’re always eager to learn from others; whether it's a new technology, a successful restoration approach, or a creative funding strategy. Collaboration and information-sharing are incredibly powerful tools in watershed management. If you’ve worked on a similar issue or simply have ideas that could help, we’d love to hear from you. The more we connect and learn from each other, the better we can protect and improve Findley Lake for generations to come.”
Following Ed’s comments, Rebecca adds: “One of the things that makes the Town of Mina so special is the strong culture of volunteerism. We’re fortunate to have many residents, often individuals who’ve had professional careers elsewhere, who bring their skills, energy, and passion to our community.
Even though we’re a small town, we benefit from a wide network of nonprofit organizations and local initiatives. For example, the Findley Lake Nature Center is actively working on trail development, and there are many other opportunities for people to get involved in stewardship, whether it’s helping maintain green spaces, supporting water quality efforts, or sharing expertise on local projects.
What’s especially unique about our community is how welcoming we are. Newcomers don’t have to wait decades to feel at home here—they’re embraced right away, and their ideas are valued. That openness has really enhanced our ability to protect Findley Lake and strengthen the town as a whole.”
In the video below, Ed reflects on the strong sense of community in the Town of Mina and the local support that fuels the ongoing efforts to protect and preserve Findley Lake:
After Ed’s remarks, Rebecca shares a few additional reflections: “One particularly meaningful designation we’ve received is from New York State, which has identified us as one of only two rural NORCs (Naturally Occurring Retirement Communities) out of 43 statewide. This designation recognizes our vibrant population of older adults and has allowed us to pursue new forms of support and services. We’re currently looking into developing a pocket neighborhood to help seniors remain in the community, where they continue to be active, involved, and deeply valued.
And here’s a fun fact that speaks to the energy of Findley Lake: it serves as the practice site for the women’s rowing team from Mercyhurst University, who happen to be the reigning national champions. Pretty cool, right?”
Yes, Rebecca, we think that’s very cool!
A heartfelt thank you to Rebecca and Ed for their partnership and for taking the time to speak with us to share their passion for protecting Findley Lake and strengthening the Town of Mina. Their leadership and collaboration exemplify the power of community-driven stewardship.

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.

Welcome to the latest edition of our “A Day in the Life” blog series! Today, we’re diving into the world of lake management, biological sampling, and watershed restoration with Patrick Rose, an Environmental Scientist and Project Manager in Princeton Hydro’s Aquatics Division.
Since joining Princeton Hydro in 2019, Pat has played a key role in a range of aquatic projects, from water quality monitoring to fisheries management. His expertise spans in-lake and watershed management, including cyanobacteria monitoring, invasive species control, and statistical analysis of water quality and biological data. Pat has contributed to major initiatives such as developing Nine Element Watershed Implementation Plans for two of New Jersey’s largest lakes, crafting cyanotoxin mitigation strategies, and conducting lake phosphorus assessments to guide restoration efforts.
His journey into aquatics began with a transformative summer course at Lake Atitlán in Guatemala, which ignited his passion for watershed science. After earning both an undergraduate degree in Environmental Science and a graduate degree in Lake Management from SUNY Oneonta, he spent a year with AmeriCorps in Knoxville, Tennessee, working on water quality initiatives with high school students and government agencies. He later completed a co-op managing aquatic invasive plants in the Pacific Northwest before joining Princeton Hydro as an intern in 2016, transitioning to a full-time role in 2019.
Now, let’s step into Pat’s boots (or waders) and see what a typical day in the field looks like, starting with the essential preparations before heading out on the water.
Pat’s days are as varied as the ecosystems he studies. When fieldwork is on the schedule, his morning starts early, often before sunrise. The first step is checking the weather forecast to anticipate any conditions that could impact the day’s work.
Next, he heads to the Princeton Hydro field office, where the team’s trucks, boats, and specialized aquatics equipment, such as the Truxor DM, Marsh Master 2MX-KC-FH, and Airboat, are stored. Before hitting the road, Pat and his team conduct a thorough inventory, gathering all necessary tools and performing critical equipment checks and calibrations.
“It’s important to ensure that all of the equipment is accounted for and in good working order before leaving for the project site because the site can be a few hours away,” Pat explains. “We calibrate our water quality meters every morning to ensure that all of our measurements are accurate.”
Even for routine monitoring projects at familiar sites, planning is essential. Some projects require full-day or multi-day sampling efforts, especially when testing large waterbodies at multiple locations. A well-structured plan helps keep the process efficient while allowing flexibility for unexpected challenges. As part of the Health and Safety Plan (HASP), the team also reviews emergency protocols, including identifying key points of contact and the nearest hospital in case of an emergency.
If the project involves a boat, the team double-checks all required safety gear, including life jackets, fire extinguishers, flares, air horns, and first aid kits. They also bring protective gloves, especially when working in areas where harmful algal blooms (HABs) are suspected. To prevent the spread of invasive species, they follow strict decontamination protocols, washing boats at the end of each field day.
With the gear packed, safety checks complete, and a solid plan in place, it’s time to hit the water and begin the day’s fieldwork.
Once Pat and the project team arrive at the site, they prepare the boat for launch and conduct a final safety check before heading out on the water.
While they may have specific sampling locations identified in advance, the team remains vigilant for any additional signs of water quality issues, such as HABs, invasive aquatic weeds, or other ecological disturbances. They also take note of positive indicators of a healthy ecosystem, including native fish species, beneficial aquatic plants, and diverse wildlife activity.
Decisions about field measurements at each location are guided by the client’s directives, an approved lake management plan, and any known or suspected water quality challenges the team is working to mitigate.
One of the primary tools Pat relies on is the multiprobe water quality meter, which allows him to efficiently measure key water quality parameters, including temperature, dissolved oxygen, pH, and specific conductivity. This instrument provides real-time data, enabling the team to assess conditions on-site and make informed decisions about sampling and management strategies.
In addition to using the multiprobe, the team collects water samples for laboratory analysis, testing for conductivity, turbidity, nutrient levels, and, in some cases, fecal coliform bacteria. Shoreline assessments are also a crucial part of monitoring efforts. Pat and his team walk the banks to document erosion, bank stability, and native plant growth, recording their observations through field notes and photo documentation.
With data collection complete, the next step is analyzing the results and translating the findings into actionable insights.
One of the projects Pat is most involved with is the trout habitat monitoring study at Lake Hopatcong, New Jersey’s largest lake. The lake’s trout fishery is a major recreational attraction, drawing anglers from across the region and contributing to the local economy. However, an analysis of 30 years of water quality data revealed a concerning trend—rising surface water temperatures, which can negatively impact trout habitat and survival rates.
In response to these concerns, the Lake Hopatcong Commission (LHC) Trout Committee was formed in 2021. Working in collaboration with the Lake Hopatcong Foundation and the Knee-Deep Club, the committee launched a three-year trout tagging study to evaluate the lake’s ability to support a sustainable trout population. Princeton Hydro is responsible for all technical aspects of the study, including data collection, analysis, and reporting, with funding provided by the New Jersey Highlands Council.
To understand how habitat conditions fluctuate during peak summer stress periods, Pat and his team conducted weekly sampling in July and August at both deep-water stations and nearshore areas. “We take GPS measurements at every site around the shoreline where we measure temperature and dissolved oxygen,” Pat explains. “Then, we send the locations to our GIS team so they can create detailed habitat maps.”
The study focuses on two key elements:
By collecting and analyzing this data, the study provides critical insights into how trout habitat is changing and what can be done to protect and enhance suitable conditions for this important fishery. Click here to read more about the Lake Hopatcong Trout Habitat and Tagging Study.
Managing aquatic projects isn’t just about addressing challenges—it’s about bringing people together to protect and enhance vital ecosystems. Successful water quality restoration efforts thrive on collaboration, education, and community engagement.
“Lakes serve many purposes, and different groups value different aspects,” Pat explains. “Fishermen often want sufficient aquatic vegetation for a healthy fishery, while boaters and swimmers typically prefer little to no vegetation. The best way to ensure a balanced approach is to involve all stakeholders in the conversation.”
At Lake Hopatcong, Pat and his team work closely with the Lake Hopatcong Commission, Lake Hopatcong Foundation, local government entities, volunteers, and community members. Regular communication and engagement efforts ensure that project goals reflect the needs of the entire community. By fostering open dialogue, gathering feedback, and sharing scientific insights, they aim to inspire stewardship and long-term investment in the lake’s health.
As Pat continues to make meaningful contributions to Princeton Hydro’s mission, he remains dedicated to expanding his expertise and leadership in lake and watershed management. He thrives on the balance between technical fieldwork, client collaboration, and mentorship, and he’s always eager to take on new challenges in aquatic science.
For students interested in the field, Pat emphasizes the value of hands-on experience: “Take as many courses as you can in aquatics and related fields,” he advises. “Seek out internships, research opportunities, or assist graduate students and professors. Real-world experience is invaluable.”
With passionate professionals like Pat leading the way, the future of lake management and watershed restoration is in good hands.

As 2024 comes to a close, we’re proud to reflect on a year filled with meaningful achievements and memorable milestones. From groundbreaking projects to personal accomplishments, these successes highlight the dedication and innovation of our team and the strength of our partnerships. None of this would have been possible without the unwavering support of our clients, collaborators, and staff.
This year marked major milestones in the restoration of three Delaware River tributaries. The removal of the 129-year-old Paulina Lake Dam on the Paulins Kill River reconnected an additional 7.6 miles of river habitat, adding to the 10 miles restored following the removal of Columbia Lake Dam. This project, led by The Nature Conservancy and designed by Princeton Hydro, represents a significant step forward in revitalizing New Jersey’s third-largest tributary to the Delaware River. The removal of Dam #2 on Bushkill Creek completed a five-dam removal effort, making the lower Bushkill Creek free-flowing and reconnecting it to the Delaware River for the first time in over 200 years. This effort enhances water quality, supports the passage of migratory fish, and bolsters freshwater mussel populations, vital to the health of the watershed. In November, work began to remove the Cedar Grove Dam, the first of four dams slated for removal along the Pequest River over the next year. This collaborative effort, led by The Nature Conservancy with training support from Princeton Hydro, will open nearly 10 miles of mainstem river and reconnect 57 miles of tributaries. Collectively, these dam removals celebrate a shared commitment to restoring ecological balance, reconnecting critical habitats, and supporting the biodiversity of the Delaware River Basin.
Through engineering and ecological enhancements, we are revitalizing landscapes across the region. In New Jersey, the 279-acre Miry Run Dam Site 21 in Mercer County Park is being transformed into a vibrant public park that balances nature and community. We also collaborated with the Trenton South Ward Neighborhood Association on a Community Garden and Park Visioning project, assisting them in securing a grant that led to the planting of 500 native plants, enhancing public spaces and creating critical habitat for monarch butterflies. In Pennsylvania, Warrington Township’s Lion’s Pride Park is being converted into a resilient wetland complex with accessible pathways, demonstrating how ecological uplift fosters healthier communities. And, construction is now complete on the Turkey Foot restoration project within the John Heinz National Wildlife Refuge at Tinicum in Philadelphia. The project revitalized 7.5 acres of critical wetland and upland habitats, preserving Pennsylvania’s last freshwater tidal marsh and supporting migratory and threatened and endangered species. In New York, we broke ground on the Spring Creek (North) Ecosystem Restoration Project in Brooklyn and Queens, which aims to restore 43 acres of degraded habitat within Jamaica Bay into a mosaic of low marsh, high marsh, scrub shrub wetland, and maritime upland within a 67-acre footprint. Meanwhile, the addition of the Marsh Master® 2MX-KC-FH to Princeton Hydro’s fleet elevated the ability to combat invasive species like Phragmites australis with minimal ecological disturbance.
Princeton Hydro was recognized as one of New Jersey’s “Top Workplaces of 2024,” a prestigious honor that highlights our commitment to fostering an inspiring and supportive work environment. Two of our project achievements received acclaim: the Musconetcong Island Park project earned both the New Jersey Future Smart Growth Award and the American Planning Association of New Jersey’s 2024 Great Places in New Jersey - Great Public Space Award for transforming an abandoned site into a riparian park. The City of Lambertville’s stormwater management initiatives received the NJDEP “Our Water’s Worth It” Award for advancing flood resilience and water quality. Additionally, the restoration of the historic Roebling Wireworks, home to our Trenton headquarters, earned the New Jersey Historic Preservation Project Award, and our President, Geoffrey Goll, PE, was honored with the “Catalyst for Sustainable Change” Award from Hold High the Torch for advancing STEAM education and environmental stewardship.
