Princeton Hydro Senior Manager of Aquatics Chris Mikolajczyk, CLM was invited as one of the select experts chosen to represent the North American Lake Management Society’s (NALMS) 314 Working Group in Washington, DC to contribute technical insight and real world expertise during discussions with congressional staff and U.S. Environmental Protection Agency (USEPA) leadership about the policies and funding resources that help communities across the country address nonpoint source pollution. What This Visit Represented for Watershed Management & Water Quality There are several federal funding programs that states, tribes, local governments, and nonprofits rely on to support critical water-quality improvement initiatives. Among them, Clean Water Act Section 319(h) is a cornerstone program that supports nonpoint source management projects like watershed-based planning, stormwater retrofits, riparian restoration, and targeted education programs. It is administered by USEPA and delivered through states and qualified tribes, and funding typically requires a nonfederal cost share to leverage local investment. In recent federal budget cycles, elements of this funding landscape have faced proposed reductions or complete eliminations by the current administration, including sharp reductions to the Clean Water and Drinking Water State Revolving Funds. Against that backdrop, the NALMS 314 Working Group organized a bipartisan “fly in” to share data, case studies, and practical policy options with Senate offices and USEPA’s Office of Water, emphasizing how programs like Section 319 translate into measurable, local water quality gains. The group, which included Committee Member Mark Heilman; NALMS Board Member Ben Rhoades; government strategist Drue Winters; and NALMS Past-President Chris Mikolajczyk, CLM, held meetings with the offices of Senators Wicker (R-MS), Markey (D-MA), Alsobrooks (D-MD), and Sanders (D-VT); both majority and minority staff of the Senate Committee on Environment and Public Works; and the EPA Office of Water leadership. Another focal point of the DC conversations was the National Lakes Assessment (NLA), a statistically rigorous survey of lake conditions conducted every five years by USEPA and its state and tribal partners. The most recent NLA, fielded in 2022, provides nationally consistent insight into ecosystem health, key stressors, and recreational indicators, and it helps policymakers understand where water quality is improving or declining and how to target investments. [gallery size="medium" link="none" ids="19352,19344,19353"] A Closer Look at Section 319(h) Created under the Clean Water Act, Section 319(h) is one of the nation’s primary funding tools for tackling runoff driven water quality issues. Through this program, states and tribes can invest in incentive-based, nonpoint source pollution reduction projects. Examples of activities eligible for 319(h) funding include watershed-based planning, BMP implementation, education and outreach, and water quality assessment and monitoring. Because 319(h) is administered through state programs, it supports local priorities while aligning with national goals. Over time, this approach has enabled communities to design watershed specific strategies, from agricultural and urban stormwater controls to nature-based green infrastructure, and to document water quality improvements with consistent methods. In most cases, a 40% non-federal funding match is required. At Princeton Hydro, we’ve seen firsthand how Section 319(h) translates into action through state run grant programs. In New Jersey, the NJDEP Water Quality Restoration Grants support projects that reduce nonpoint source pollution, mitigate harmful algal blooms, restore riparian areas, enhance watershed and climate resilience, and restore water quality in New Jersey. The grants are funded through Section 319(h) and administered by NJDEP’s Watershed & Land Management Program. Princeton Hydro is proud to be a partner on five of the 17 projects most recently awarded funding (2025) through NJDEP’s Water Quality Restoration grants. Our contributions vary by project and encompass activities such as engineering design, water quality assessment, watershed-based planning, and technical support for implementing stormwater and habitat restoration measures. We also supported several partners in developing successful NJDEP Section 319(h) applications, including technical documentation, cost estimates, conceptual designs, and pollutant load reduction estimates. To take a deeper dive into our most recent collaborations, click here to read our blog: NJDEP Awards $8M for Water Quality Restoration Projects Advocacy Outcomes Princeton Hydro is grateful to NALMS and our fellow 314 Working Group members for convening this effort, and to the Senate offices and USEPA leaders who engaged in thoughtful, solutions-oriented conversations. These conversations are already translating into tangible results. Following these coordinated advocacy efforts Clean Water Act Section 319(h) funding was restored in the federal budget with an increase of $750,000. More broadly, the U.S. Environmental Protection Agency ultimately fared better than many federal agencies during the most recent budget cycle, with several programs initially proposed for reduction or elimination reinstated through congressional negotiations. Chris Mikolajczyk is a Certified Lake Manager and aquatic ecologist with over 35 years of experience in conducting the management, oversight, and coordination of water resource projects in three main areas: aquatic resource restoration and management; aquatic ecosystem sampling and investigations; and stormwater quality modeling and management.

The Delaware River is a lifeline for more than 14 million people, a refuge for wildlife, and a defining natural feature of the region. In recent years, HABs, once confined mostly to lakes and ponds, have expanded into streams and rivers and appearing in colder months. Understanding why this shift is happening, and how to predict it, is essential for protecting water quality, public health, and ecological resilience within the Delaware River watershed and watersheds nationwide. The podcast, hosted by Fran Chismar and Tom Knezick of Pinelands Nursey, highlights the urgency of addressing HABs and the innovative, cross‑sector partnership driving this work forward. Listen now: Harmful Algal Blooms with Dr. Fred Lubnow and Jenn Rogers. Stewardship and Community Leadership from FoHVOS Jenn Rogers, Executive Director of FoHVOS, brings two decades of conservation leadership to the partnership. Her background spans naturalist education, ecological stewardship, and the development of large-scale restoration and public engagement programs. During her fourteen years with the Mercer County Park Commission, she helped establish both the Environmental Education and Stewardship Departments and oversaw the care of more than ten thousand acres of parkland. Jenn has spent her career building programs that connect people to the landscapes around them. Her commitment to community-driven conservation make her a key partner in a project that relies on both scientific rigor and public participation. Her perspective highlights how land use, watershed health, and community stewardship are deeply interconnected. Expertise Shaping the Future of HAB Research Dr. Fred Lubnow serves as Princeton Hydro’s Senior Technical Director of Ecological Services and brings more than 30 years of experience in limnology, watershed restoration, and community and ecosystem ecology. His career has focused on understanding how freshwater systems respond to nutrient loading, hydrologic change, and long-term environmental pressures. He has designed and led numerous lake and watershed restoration projects, developed USEPA Nine-Element and TMDL-driven watershed plans, and created field-based cyanobacteria and cyanotoxin monitoring programs that are now used across the region. Fred’s expertise in the taxonomy, ecology, and management of algae, particularly cyanobacteria, has made him a leading voice in the study of HABs. He currently serves on New Jersey’s HABs Advisory Team, where he helps interpret water quality data and advises on mitigation strategies. His scientific leadership guides the technical design and implementation of the Delaware River HAB monitoring initiative. A Collaborative Approach to Understanding HABs Now entering its second year, the Delaware River HAB monitoring initiative is expanding both its scientific scope and its community engagement efforts. Building on the foundation established in 2025, the project team is conducting multi‑season drone flights, enhanced satellite‑based surveys, and targeted on‑the‑water sampling along 73 miles of the Delaware River and 24 connected waterbodies. These efforts are designed to strengthen the project’s ability to detect and forecast HABs under a wide range of seasonal and environmental conditions. [gallery link="none" columns="2" ids="19329,19330"] Year two also introduces several tools and activities intended to support broader participation and more efficient data collection. This includes the launch of a new ArcSurvey123 mobile data platform to support real‑time volunteer water quality submissions, as well as expanded training opportunities for community members interested in assisting with field sampling. Data collected through these efforts will contribute to the development of advanced algorithms capable of forecasting HAB occurrence at multiple spatial scales. Funded by the National Fish and Wildlife Foundation's (NFWF) Delaware Watershed Conservation Fund (DWCF), in partnership with U.S. Fish & Wildlife Service, the project continues to be supported by a diverse network of partners across New Jersey and Pennsylvania, including The City University of New York's (CUNY) New York City College of Technology (City Tech), Trenton Water Works, Mercer County Park Commission, The College of New Jersey, Aqua-PA, Philadelphia Water Department, Bucks County Conservation District, Turner Designs, and US Army Corps of Engineers - Philadelphia District's Blue Marsh Lake. Together, these organizations contribute technical expertise, watershed knowledge, and crucial on‑the‑ground support. This collaborative approach remains central to the initiative’s success and long‑term objective: establishing a scalable HAB‑forecasting framework that can ultimately be applied to additional watersheds across the United States.

Another highlight of the conference for our team was a field trip to The Nature Conservancy in New Jersey’s South Cape May Meadows, where participants explored the newly completed boardwalk, a Princeton Hydro-designed project that creates a half‑mile, universally accessible route through one of the region’s most ecologically significant landscapes. Commissioned by The Nature Conservancy in New Jersey and installed by Renova Environmental Company, the project was designed to provide inclusive public access and opportunities for environmental education while carefully protecting a fragile ecosystem that serves as a vital stopover along the Atlantic Flyway.
Designing a public trail within such a dynamic wetland system required a careful balance between human experience and habitat preservation, with the goal of creating an inviting, educational, and fully accessible route without disturbing critical hydrology, soils, or wildlife. Walking the boardwalk alongside fellow NJCRC Conference participants was a meaningful, full-circle moment for our team, bringing the project’s vision to life.
Huge thanks to New Jersey Coastal Resilience Collaborative and New Jersey Department of Environmental Protection for pulling together another incredible conference. We headed home with new connections, new ideas, and a renewed sense of pride in the work we all do!
Dr. Fred Lubnow, Princeton Hydro's Senior Technical Director of Ecological Services, and Jenn Rogers, Executive Director of Friends of Hopewell Valley Open Space (FoHVOS), were recently featured on the Native Plants, Healthy Planet podcast to discuss the collaborative, first‑of‑its‑kind initiative to monitor Harmful Algal Blooms (HABs) in the Delaware River Watershed using drones, spatial analysis, and community science.
The Delaware River is a lifeline for more than 14 million people, a refuge for wildlife, and a defining natural feature of the region. In recent years, HABs, once confined mostly to lakes and ponds, have expanded into streams and rivers and appearing in colder months. Understanding why this shift is happening, and how to predict it, is essential for protecting water quality, public health, and ecological resilience within the Delaware River watershed and watersheds nationwide.
The podcast, hosted by Fran Chismar and Tom Knezick of Pinelands Nursey, highlights the urgency of addressing HABs and the innovative, cross‑sector partnership driving this work forward. Listen now: Harmful Algal Blooms with Dr. Fred Lubnow and Jenn Rogers.
Jenn Rogers, Executive Director of FoHVOS, brings two decades of conservation leadership to the partnership. Her background spans naturalist education, ecological stewardship, and the development of large-scale restoration and public engagement programs. During her fourteen years with the Mercer County Park Commission, she helped establish both the Environmental Education and Stewardship Departments and oversaw the care of more than ten thousand acres of parkland.
Jenn has spent her career building programs that connect people to the landscapes around them. Her commitment to community-driven conservation make her a key partner in a project that relies on both scientific rigor and public participation. Her perspective highlights how land use, watershed health, and community stewardship are deeply interconnected.
Dr. Fred Lubnow serves as Princeton Hydro’s Senior Technical Director of Ecological Services and brings more than 30 years of experience in limnology, watershed restoration, and community and ecosystem ecology. His career has focused on understanding how freshwater systems respond to nutrient loading, hydrologic change, and long-term environmental pressures. He has designed and led numerous lake and watershed restoration projects, developed USEPA Nine-Element and TMDL-driven watershed plans, and created field-based cyanobacteria and cyanotoxin monitoring programs that are now used across the region.
Fred’s expertise in the taxonomy, ecology, and management of algae, particularly cyanobacteria, has made him a leading voice in the study of HABs. He currently serves on New Jersey’s HABs Advisory Team, where he helps interpret water quality data and advises on mitigation strategies. His scientific leadership guides the technical design and implementation of the Delaware River HAB monitoring initiative.
Now entering its second year, the Delaware River HAB monitoring initiative is expanding both its scientific scope and its community engagement efforts. Building on the foundation established in 2025, the project team is conducting multi‑season drone flights, enhanced satellite‑based surveys, and targeted on‑the‑water sampling along 73 miles of the Delaware River and 24 connected waterbodies. These efforts are designed to strengthen the project’s ability to detect and forecast HABs under a wide range of seasonal and environmental conditions.
Year two also introduces several tools and activities intended to support broader participation and more efficient data collection. This includes the launch of a new ArcSurvey123 mobile data platform to support real‑time volunteer water quality submissions, as well as expanded training opportunities for community members interested in assisting with field sampling. Data collected through these efforts will contribute to the development of advanced algorithms capable of forecasting HAB occurrence at multiple spatial scales.
Funded by the National Fish and Wildlife Foundation's (NFWF) Delaware Watershed Conservation Fund (DWCF), in partnership with U.S. Fish & Wildlife Service, the project continues to be supported by a diverse network of partners across New Jersey and Pennsylvania, including The City University of New York's (CUNY) New York City College of Technology (City Tech), Trenton Water Works, Mercer County Park Commission, The College of New Jersey, Aqua-PA, Philadelphia Water Department, Bucks County Conservation District, Turner Designs, and US Army Corps of Engineers - Philadelphia District's Blue Marsh Lake. Together, these organizations contribute technical expertise, watershed knowledge, and crucial on‑the‑ground support. This collaborative approach remains central to the initiative’s success and long‑term objective: establishing a scalable HAB‑forecasting framework that can ultimately be applied to additional watersheds across the United States.

Friends of Hopewell Valley Open Space (FoHVOS), in partnership with Princeton Hydro, has launched a groundbreaking initiative, “Monitoring Harmful Algal Blooms (HABs) in the Delaware River Watershed Using Drones and Spatial Analysis,” to improve understanding and forecasting of HABs throughout the Delaware River Watershed. Funded by the National Fish and Wildlife Foundation (NFWF), in partnership with the U.S. Fish & Wildlife Service, through the Delaware Watershed Conservation Fund (DWCF), the project leverages drone technology and advanced data modeling to identify environmental conditions that contribute to HAB formation and aims to develop tools and methodologies for early detection and management.
For this innovative research project, FoHVOS, a 501(c)3 and accredited Land Trust located in Hopewell Township, NJ, has teamed with Princeton Hydro. Princeton Hydro conceptualized and designed the initiative and is leading the technical implementation, including field survey design, drone operations, data analysis, and volunteer training.
“The Delaware River is central to Hopewell Valley’s identity. It shapes our way of life, supplies drinking water to 14.2 million people, shelters wildlife like the endangered Atlantic sturgeon, and offers abundant outdoor recreation,” said Jennifer Rogers, Executive Director of FoHVOS. “HABs were once confined to ponds and lakes, but since 2018, they’ve appeared in colder months and spread to streams and rivers. Though land trusts traditionally focus on land, HABs show how land use directly affects water. These blooms often stem from excess nitrogen and phosphorus washed into waterways during storms. Protecting water means restoring land. Our partnership with Princeton Hydro aligns perfectly with our mission. Together, we’re working to better understand and safeguard the Delaware River and its tributaries in both NJ and PA.”
HABs, caused by nuisance growth of cyanobacteria, can have detrimental effects on water quality and are a growing environmental concern nationwide. These blooms deplete oxygen levels, release toxins, and disrupt ecosystems, potentially posing serious risks to drinking water supplies and the health of wildlife, pets, humans, and local economies. Despite advances in environmental monitoring, predicting when and where HABs will occur remains a challenge due to the complex interplay of nutrient loading, temperature, and hydrologic conditions that can lead to rapid bloom proliferation.
To address these challenges, this newly launched initiative integrates drone-based remote sensing, field sampling, and spatial data analysis to collect and interpret detailed environmental data over a two-year period. The study spans multiple monitoring sites along a 73-mile stretch of the Delaware River in New Jersey and Pennsylvania, focusing on near-shore sections and 23 associated waterbodies. The first survey event began in August 2025.
Drones equipped with multispectral imaging systems capture high-resolution spatial data that is then integrated with digital platforms to link remote-sensing with the drone data and on-the-water collected data. The field-based water quality measurements are being collected by a team of trained community volunteers who are using phycocyanin fluorometer meters to measure concentrations of the photosynthetic pigment phycocyanin, which is produced primarily by cyanobacteria. Volunteers enter the data into a customized ArcGIS mobile-friendly survey. These combined datasets will be used to develop and validate predictive algorithms for both planktonic and benthic HABs under varying seasonal and hydrologic conditions.

The New Jersey Department of Environmental Protection (NJDEP) recently announced $8 million in Water Quality Restoration Grants to support projects that reduce nonpoint source pollution, mitigate harmful algal blooms, restore riparian areas, and enhance watershed and climate resilience. Funded through Section 319(h) of the federal Clean Water Act and administered by the DEP's Watershed and Land Management Program, these grants were awarded to municipalities, nonprofit organizations, and academic institutions across the state.
Princeton Hydro is proud to be a partner on five of the 17 funded projects. Our contributions vary by project and encompass activities such as engineering design, water quality assessment, watershed-based planning, and technical support for implementing stormwater and habitat restoration measures. Let's take a deeper look at these collaborative efforts:
The Watershed Institute received $205K in 319(h) grant funding to develop a watershed-based plan for the Assunpink Creek watershed, located within the Raritan River Basin. This watershed spans 11 municipalities across two counties, where varied landscapes and demographics share common challenges such as localized flooding, stormwater management, and water quality degradation, highlighting the need for a coordinated, watershed-wide, science-driven approach.
The plan will evaluate pollution sources and identify large-scale restoration opportunities, including green infrastructure and riparian buffer restoration, to improve water quality and reduce flooding. It will also assess the cost, feasibility, and pollutant reduction potential of proposed measures to ensure practical implementation. Princeton Hydro supported the Institute in developing the grant proposal and planning framework, leveraging our expertise in watershed-based planning to prioritize nature-based solutions that address both water quality and climate resilience. This initiative represents a critical step toward regional collaboration, enabling upstream and downstream communities to work together on strategies that strengthen watershed health, protect public safety, and build long-term resilience.
The Lake Hopatcong Commission (LHC) was awarded $366K to retrofit an existing stormwater detention basin between King Road and Mount Arlington Boulevard in Roxbury Township. This retrofit is part of a larger Watershed Implementation Plan that Princeton Hydro developed in collaboration with LHC, which prioritizes nutrient reduction and stormwater management strategies across the Lake Hopatcong watershed. Over the past several years, LHC has actively implemented multiple elements of this plan to address harmful algal blooms (HABs) and improve water quality.
For this project, Princeton Hydro is providing engineering design and technical oversight to transform the existing basin into a green stormwater infrastructure system that slows, captures, and naturally treats runoff before it enters King Cove. The design incorporates native vegetation, invasive species management, and erosion control measures to stabilize soils and filter pollutants, reducing nutrient loading, which is one key driver of HABs. Public outreach and pre- and post-construction water quality monitoring will ensure performance tracking and measurable improvements. This basin retrofit represents a critical step in a coordinated, science-based approach to restoring ecological health and water quality in New Jersey’s largest lake.
Jefferson Township received $350K in grant funding to develop an Emerging Contaminants Management Plan for Cozy Lake, focusing on cyanotoxins and HABs. Cozy Lake is a 28-acre waterbody within a 1,152-acre sub-watershed that includes both forested (60%) and developed (29%) land. The lake is fed by the Rockaway River at its northern end and a smaller southeastern inlet, with outflow through a dam on the western edge.
The shoreline is primarily residential lawn with minimal emergent wetlands, and several inlets and rock-lined drainage ditches exhibit erosion and lack slope protection, contributing to sediment loading. Princeton Hydro provided early technical input to shape this innovative project with the creation of a comprehensive Jefferson Township Lake and Watershed Restoration and Protection Plan. As part of the plan, Princeton Hydro made recommendations for Cozy Lake, which included enhancing shoreline buffers with native vegetation and installing living shorelines at select properties to stabilize soils, filter stormwater and reduce nutrient loading, improve habitat quality, and enhance community access. These measures, combined with in-lake monitoring and proactive management strategies, will help mitigate HABs and protect ecological and public health.
Rockaway Township received $399K in grant funding to implement elements of its Watershed Implementation Plan, focusing on green infrastructure stormwater management and nutrient reduction to improve water quality. The project will retrofit the municipal complex by converting a rock-lined drainage swale into a vegetated swale with a bioretention basin, designed to filter stormwater runoff and reduce nonpoint source pollutants entering Fox’s Pond and Fox Brook.
Princeton Hydro played a key role in developing the Watershed Implementation Plan, which encompasses 11 private lakes within the Rockaway River watershed, prioritizing critical locations for intervention and designing cost-effective green infrastructure BMPs. This regional approach aligns with strategies recommended by NJDEP and the Highlands Council. The plan included a comprehensive watershed-based assessment to identify and quantify factors contributing to eutrophication, evaluate management measures, estimate costs, and establish an implementation schedule. Princeton Hydro authored the final report, which guided the Township in applying for the Section 319(h) grant and now informs the design and construction of green stormwater infrastructure that will deliver measurable water quality improvements while supporting ecological restoration goals.
Green Trust Alliance (GTA), a nationally accredited land trust and public charity dedicated to accelerating large-scale conservation, received $1.39 million in NJDEP funding to implement green infrastructure improvements at Pinelands Regional High School in Tuckerton, New Jersey. This initiative targets the Tuckerton Creek watershed, which drains into Tuckerton Creek and ultimately flows into Barnegat Bay—a critical estuary spanning 33 municipalities in Ocean County and four in Monmouth County. The retrofit will transform the school’s stormwater detention basin into a multi-functional system that mimics natural hydrology, enhances flow control, and improves water quality locally and in the larger Barnegat Bay watershed.
Working with GTA and GreenVest, Princeton Hydro is serving as the design engineer, applying nature-based engineering and ecological restoration techniques to intercept, evapotranspire, and infiltrate stormwater runoff at its source. In addition to its technical objectives, the effort includes a strong community engagement component and an educational platform for students. By bringing green infrastructure into the school environment, the initiative provides hands-on experience with water resources, stormwater management, and ecological engineering, help to build STEM skills while fostering a deeper connection to the surrounding landscape and an understanding of how natural systems work together to support environmental and community health.
Princeton Hydro also assisted several of these partners in developing successful NJDEP Section 319(h) grant applications, providing technical documentation, conceptual designs, and pollutant load reduction estimates to strengthen the proposals.
To date, the Murphy Administration has awarded more than $33M in Water Quality Restoration grants to improve the health of waterways in all corners of the state. Click here to read about all the 2025 grant funding recipients and their innovative projects.
As NJDEP Environmental Protection Commissioner Shawn M. LaTourette noted in the department's press release, “Enhancing the ecological health of our lakes, rivers, streams and coastal waters has long been a priority of the Murphy Administration. The Department of Environmental Protection is pleased to award these grants that will help our partners advance a variety of strategies to improve the health of these waterways and enhance the quality of life in our communities.”
