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.

“This research project represents a major step forward in how we study and manage harmful algal blooms at the watershed scale,” said Dr. Fred Lubnow, Project Lead and Senior Technical Director of Ecological Services at Princeton Hydro. “By integrating satellite data, drone imagery, and on-the-water sampling, we’re developing predictive tools that will enable us take a proactive approach to mitigate HABs, improve response time, and better support our ecosystem health.”

Project partners include New York City College of Technology – The City University of New York, which donated the drone and is supporting remote sensing and data integration; Trenton Water Works, Mercer County Park Commission, and The College of New Jersey which are providing monitoring sites and contributing volunteers for water quality data collection in New Jersey; Aqua-PA and the Philadelphia Water Department, which are providing monitoring sites and volunteers to collect watershed data in Pennsylvania; the Bucks County Conservation District, which is coordinating volunteer data collection; and Turner Designs, whose advanced phycocyanin sensors are being used to calibrate and validate drone-based monitoring data.

In the photos below, volunteers are being trained by Princeton Hydro staff on how to use phycocyanin fluorometers and Secchi disks to gather water quality data and log their findings.

This $1M project is funded through a $488,400 NFWF DWCF grant as part of the NFWF’s Research, Monitoring, & Evaluation Grant category and $513,700 in matching funds from project partners. This grant category aims to support high-performing science that is inclusive, adaptive, and innovative, with the potential to transform the Delaware River Watershed’s future through improved conservation, restoration, and public engagement.

Once complete, the project will produce a comprehensive report summarizing methods, analyses, and data-driven recommendations for practical, low-cost HAB monitoring and mitigation strategies that can be replicated across the Delaware River Watershed and beyond. Crucially, the report will identify tributaries and sources contributing to riverine HABs, enabling targeted restoration of the most affected lands and waters. Data collection will continue through Fall 2025, resume in Spring/Summer 2026, and culminate in a final report expected in 2027.

We’re excited to announce Senior Wildlife Biologist and Ecologist Mike McGraw, CSE, QAWB, ACE is a co-author of a newly published study in Agriculture, Ecosystems & Environment, a leading journal in agroecological research. The paper, “Is regenerative agriculture for the birds? Outcomes are practice and species specific,” offers fresh insight into how regenerative farming practices affect the abundance and diversity of bird species across working landscapes in the Northern Great Plains of the US and Canada.

The full paper is available for free via an open-access link until January 13. We encourage everyone interested in wildlife conservation, regenerative agriculture, or avian ecology to take advantage of this limited-time access. Click here to read it now.

What the Study Explores

Regenerative agriculture is often heralded as a win-win for soil health, productivity, and biodiversity, but how exactly do these practices affect bird communities? Birds are highly sensitive to agricultural change, and many North American species have experienced significant declines due to intensification of farming practices. The newly published study takes a closer, science-driven look at whether regenerative approaches can help reverse these trends.

Drawing on extensive point counts, distance sampling, and acoustic recording units across agricultural landscapes, the research team examined nine common regenerative practices, including cover cropping, integrating livestock, eliminating tillage, and enhancing field margins. Rather than assuming a blanket benefit, the study asked a nuanced question: Which birds benefit from which practices, and why?

The findings show that:

Regenerative practices do influence bird density, but the effects are both practice-specific and species-specific.
Some practices, such as maintaining field margins, integrating livestock, and reducing or eliminating tillage, tended to support higher densities of multiple bird species, including several grassland obligates.
Birds responded more strongly to on-farm, field-level practices than to broader land-use patterns across the surrounding landscape.
While regenerative practices can provide important conservation value without removing land from production, they should complement (not replace) grassland preservation and restoration efforts.

This work helps refine what regenerative agriculture can contribute to working-lands conservation and provides actionable, species-specific insights for farmers, land managers, and conservation practitioners.

Princeton Hydro was proud to participate in the New Jersey Association for Floodplain Management (NJAFM) 20th Annual Conference and Exhibition, held this fall in Atlantic City, NJ. Celebrating two decades of collaboration and innovation within the floodplain management community, the conference brought together more than 500 practitioners, researchers, agency staff, and industry leaders from across the Northeast.

As the region’s premier floodplain management event, the NJAFM conference serves as a hub for sharing cutting-edge tools, best practices, and real-world strategies that help communities reduce flood risk, adapt to changing climate conditions, and build long-term resilience. Over the course of two days, participants attended educational sessions, hands-on training, and networking events centered on the theme: “NJAFM at 20 Years: Celebrate the Past, Focus on the Future.”

Princeton Hydro was excited to return as a conference sponsor, exhibitor, and session presenter.

Understanding the Role of Floodplain Management

Floodplain management is a multidisciplinary practice that integrates planning, engineering, ecological science, and public policy to reduce flood risk while preserving the natural functions of riverine and coastal systems. At its core, it involves understanding how water moves across a landscape, identifying areas vulnerable to flooding, and implementing measures that protect people, infrastructure, and ecosystems.

Floodplains provide a range of essential functions. Hydrologically, they convey, store, and infiltrate water during storm events, supporting natural flood attenuation, erosion control, and groundwater recharge. Ecologically, they contribute to biodiversity by providing habitat, migration corridors, and spawning areas for fish and wildlife. From a community perspective, well-managed floodplains can offer recreational value, improve water quality, and enhance the aesthetic and economic vitality of local neighborhoods.

Modern floodplain management relies on both structural and non-structural approaches. Structural measures may include engineered solutions such as levees, floodwalls, culvert improvements, or stormwater system upgrades. Non-structural tools often involve land-use planning, flood-resilient building standards, conservation of open space, and community engagement programs that help residents understand risk and adopt best practices.

Princeton Hydro works with municipalities, state agencies, nonprofit organizations, and watershed groups to develop and implement comprehensive floodplain management strategies across the region, emphasizing strategies that balance flood risk reduction with ecological enhancement, ensuring that floodplain management supports both resilient communities and healthy, functioning watersheds.

The Lake Hopatcong Commission, in partnership with Roxbury Township and Princeton Hydro, and with support from the Lake Hopatcong Foundation, has been awarded a $367,000 Water Quality Restoration Grant from the New Jersey Department of Environmental Protection (NJDEP) for the Lake Hopatcong Watershed Basin Enhancement Project.

The project will retrofit an existing stormwater detention basin with a series of green stormwater infrastructure improvements designed to slow, capture, and naturally treat stormwater runoff. The basin project, located between King Road and Mount Arlington Boulevard in Roxbury Township, was identified in the 2021 Upper Musconetcong River Implementation Plan (WIP) as a priority project to reduce non-point source pollution and improve water quality before stormwater enters the lake at King Cove.

"Roxbury is truly thankful for the Lake Hopatcong Commission. Lake Hopatcong is such a valuable resource and the commission’s work alongside Princeton Hydro has preserved a natural treasure," said Shawn Potillo, Mayor of Roxbury. "We are grateful to the NJDEP for their support and award of this grant. This water basin project in Roxbury will help continue the commission’s purpose of keeping the lake a beautiful place to swim, boat, relax, and call home."

A range of improvements will be incorporated including planting native vegetation and managing invasive species to stabilize soils, support wildlife, and naturally filter pollutants before they reach the lake. Erosion and sediment control measures will further protect the area by reducing stormwater scouring and preventing bank degradation.

In addition to on-the-ground restoration, the project emphasizes public education and outreach to promote best management practices and ongoing watershed stewardship among residents and local partners. Project success will be evaluated through water quality monitoring conducted before and after construction, providing measurable data on the project’s effectiveness in improving water quality.

“Lake Hopatcong’s fight against harmful algal blooms requires a united front, where many projects, like retrofitting stormwater basins to capture nutrients before they go into the lake, collectively make a big impact,” said Dr. Fred Lubnow, Senior Technical Director of Ecological Services at Princeton Hydro. “Thanks to the leadership of the Lake Hopatcong Commission and the Lake Hopatcong Foundation, this collaborative approach is driving real progress toward cleaner water, healthier ecosystems, and a more resilient future for New Jersey’s largest lake.”

The basin enhancement project is funded through NJDEP’s Water Quality Restoration Grant Program, which is supported by the U.S. Environmental Protection Agency under Clean Water Act Section 319(h). Along with the state grant, the project includes a $200,000 local match from the Commission, Roxbury Township, and the Lake Hopatcong Foundation, and builds on a $98,000 planning grant awarded by the New Jersey Highlands Council in 2024 that helped prepare the project for implementation and future grant opportunities.

“This project represents an important step forward in improving Lake Hopatcong’s water quality and reducing pollutants that contribute to harmful algal blooms,” said Ron Smith, Chairman of the Lake Hopatcong Commission. “We’re grateful to NJDEP, Roxbury Township, Princeton Hydro, the Foundation and the Highlands Council for their continued partnership in protecting this vital resource.”

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:

1. The Watershed Institute – Watershed-Based Planning for Assunpink Creek

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.

2. Lake Hopatcong Commission – Watershed-Based Stormwater BMPs

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.

3. Cozy Lake, Jefferson Township – Addressing Emerging Contaminants

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.

4. Rockaway Township – Watershed-Based Green Infrastructure

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.

5. Green Trust Alliance – Green Infrastructure and Community Engagement

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.”

Nicole joined Princeton Hydro in 2007, starting in the former Voorhees, NJ office with administrative tasks like answering phones, ordering supplies, and organizing files. Before long, she took on a much larger responsibility: helping coordinate the construction of Princeton Hydro’s Southern Regional Office in Sicklerville, NJ. The new space was designed to accommodate the firm’s growing staff and house the Geotechnical Soils Testing Laboratory, a facility accredited by the American Association of State Highway and Transportation Officials (AASHTO) and validated by the U.S. Army Corps of Engineers (USACE) Materials Testing Center (MTC) to perform a full range of tests.

“The office construction project was my first taste of special projects management,” Nicole reflects. “From pouring concrete, coordinating with the movers to relocate the entire office to the new office, and working with the team installing furniture, I was involved in almost every detail. I still have all the original documents and notes from that time.”

Over the years, inspired by the many women in leadership roles at Princeton Hydro, Nicole worked hard to grow into her own influential path. "Working alongside such talented and dedicated women showed me what leadership looks like in action, and motivated me to grow, learn, take on new challenges every day, and pursue my own professional goals."

Today, alongside her Office Management and Special Projects responsibilities, Nicole manages Princeton Hydro’s Health & Safety Program in partnership with Chief Operating Officer Megan Hunter Ruff and Regional Safety Leaders (RSLs) Jerry Vogel, Chris Mikolajczyk, CLM, and Casey Pantaleo, PE. She has been instrumental in formalizing and advancing the program’s systems and practices. "I take great pride in knowing that I play a key role in implementing a Health & Safety Program that protects our employees in their specific line of work and ensures that everyone goes home safely."

Starting the Day: Coffee, Calendars, & Checklists

Nicole’s day begins at 8:00 AM, caramel iced latte in hand. After scanning her inbox and calendar, she sets her priorities for the day, though she knows her plan may shift at any moment.

“I’m constantly juggling tasks, solving problems, and adapting on the fly,” Nicole says with a laugh. “What surprises people most is how unpredictable my day can be, and how many different team members I connect with across projects. Some mornings, I’ll talk to fifteen employees before I even drink my second cup of coffee!” One moment Nicole is coordinating health and safety needs, the next she’s ordering lunch for the team, and later she’s assisting with a proposal submission. No two hours, let alone two days, look the same!

Interwoven with the many tasks on Nicole’s to-do list each day are her health and safety responsibilities, which she views as mission critical. She creates “Toolbox Talks” and newsletter updates on various health and safety topics, verifies all staff certifications are valid and current, reminds staff of required safety trainings, and works with team members to order specific Personal Protective Equipment (PPE), including safety vests, masks, hard hats, and other field gear. Nicole also keeps the Health & Safety Program current by reading safety-industry publications and attending virtual OSHA-regulated training courses, ensuring both the company protocols and her own knowledge evolve with the latest standards. Her role centers on coordinating and administering the program logistics, compliance tracking, and staff resources, rather than acting as a certified technical safety professional.

Success, she says, comes down to collaboration, flexibility, and attention to detail. “Honestly, no one has it all figured out. My role is constantly evolving, so I rely on my notebook to track tasks and stay organized. I’m always open to feedback and enjoy learning from those around me - teamwork is everything, and a steady supply of coffee doesn’t hurt either!”

Projects, People, & Safety

Nicole’s role is unique in that she bridges multiple departments and disciplines within Princeton Hydro. As Health & Safety Program Lead, she works closely with the COO, RSLs, and many other technical staff across the company, a collaboration ensures that while Nicole steers the day-to-day systems, the technical experts remain at the core of the program's success.

Nicole takes immense pride in Princeton Hydro's comprehensive Health & Safety Program. “It became my baby,” she says. “Safety doesn’t always get the spotlight, but it’s essential and the backbone of everything we do here at Princeton Hydro. Every time I help someone navigate a challenge or ensure they have the right tools and support, I know I’m contributing to both their success and their safety, and that feels great!"

Nicole puts a lot of effort into making sure staff are prepared and equipped to handle the unique risks of environmental engineering and in-the-field science. Maintaining a strong Health & Safety Program at Princeton Hydro involves a lot of research, planning, budgeting, and communication, including:

Tracking certifications and licenses for staff across all disciplines;
Sending reminders about renewals and coordinating required safety trainings, including First Aid, Hazardous Waste Operations and Emergency Response, Confined Space Awareness, equipment training, and more;
Regularly reviewing and updating documentation to align with OSHA regulations;
Conducting safety checks and audits for Princeton Hydro's fleet of trucks;
Working with the technical RSLs to complete safety audits of the Geotechnical Soils Testing Laboratory as well as specialized machinery like the Marsh Master; and
Providing staff with health and safety updates, including resources, videos, and flyers that staff can use when completing their Activity Hazard Analyses (AHAs).

Beyond the checklists and compliance requirements, Nicole also looks for creative ways to keep safety top of mind. By creating and sharing safety-themed memes, she makes important reminders easier to remember and a lot more fun. Here are a few of our favorites:

[gallery link="none" size="large" columns="2" ids="18144,18143"]

For special projects, risk assessment and mitigation start on day one. Nicole reviews project goals, timelines, and team roles with a critical eye, helping to identify potential challenges, whether logistical, regulatory, or health and safety related. By asking questions and gathering input from both field staff and managers, she zeroes in on the right Health & Safety experts to guide the team and flags anything that could derail success.

For Nicole, every challenge is also an opportunity. She welcomes the twists and turns that come with her work, letting new projects and unexpected needs guide her growth. “There’s always something new to learn or take on, and I’ve learned to stay open to wherever the day leads me."

Looking Ahead

After 18 years with Princeton Hydro, Nicole continues to approach her role with curiosity and momentum. She is committed to refining and expanding the Health & Safety Program, not by resting on what already works, but by seeking out new opportunities to make systems more efficient, accessible, and effective. She welcomes input from colleagues and pairs it with her own creative problem-solving to build tools that support the entire team.

Looking ahead, one of Nicole’s top priorities is creating a centralized internal platform that gives staff easy access to safety resources, training reminders, Active AHAs, and comprehensive program documents, whether they’re in the office or out in the field. To bring this vision to life, she’s collaborating closely with the COO and RSLs, combining operational insight with technical safety expertise to build a system that’s both practical and comprehensive for the entire company.

At the end of the day, Nicole’s goal is simple: give her colleagues the confidence to do their best work, backed by the training, tools, and systems that keep them safe. “My highest priority is ensuring that every employee returns home safely to their loved ones at the end of each day. Nothing I do is more important than protecting the health and well-being of our team.”

Princeton Hydro's Director of Aquatics, Michael Hartshorne, recently traveled to Pietermaritzburg, South Africa, to present at the Southern African Society for Aquatic Scientists (SASAqS) Congress 2025. Hosted by the Institute of Natural Resources (INS) and the University of KwaZulu-Natal, the annual event convened researchers, industry professionals, government officials, and students from around the world to advance aquatic science by linking research with real-world practice.

Over the course of five days, participants shared insights on critical global and regional issues, including water pollution, water security, biodiversity conservation, climate change adaptation, and community-based resource management. The program featured an array of interdisciplinary presentations spanning hydrology, freshwater ecology, and policy, while also creating space for collaboration and connection through interactive workshops, poster sessions and exhibits, networking events, and a gala dinner and awards ceremony. On the closing day, field trips brought attendees out into the surrounding landscape, offering a tangible backdrop to the themes explored throughout the conference.

Michael's Presentation on Harmful Algal Blooms

On the opening day of the SASAqS Congress 2025 program, Michael addressed the full conference audience with a presentation titled “Novel Techniques for the Monitoring of Harmful Algal Blooms (HABs) in Lakes and Rivers of the United States,” which focused on innovative approaches for detecting and managing HABs, a growing worldwide concern driven by nutrient pollution and climate change. Michael illustrated how innovative research can inform practical management strategies while encouraging global collaboration.

HABs are intensifying in frequency, scale, and severity worldwide, presenting challenges for drinking water supplies, recreational lakes, and river ecosystems. Michael’s presentation showcased a suite of monitoring tools, from handheld phycocyanin and phycoerythrin meters, to drones with multispectral lenses, to advanced techniques such as qPCR (quantitative Polymerase Chain Reaction), microscopy, and akinete cell monitoring. Through case studies from lakes, reservoirs, and river systems in New Jersey, Virginia, and Pennsylvania, he highlighted the strengths and limitations of each method, emphasizing the importance of tailoring monitoring strategies to the unique conditions of each waterbody. Michael also discussed management interventions and highlighted how emerging technologies can support more adaptive, science-driven management of HABs.

In the Field: Aquatic Science in Action

The conference concluded with optional field trips that gave participants a chance to view South Africa’s aquatic systems and management challenges firsthand. Each excursion highlighted a different aspect of aquatic science in practice:

UKZN Zebrafish Research Facility: On the University of KwaZulu-Natal’s Pietermaritzburg campus, this outing introduced participants to the zebrafish as a model organism for studying genetics, development, and aquatic toxicology. The tour provided a window into laboratory-based aquatic science and its applications to regional and global challenges.
Lions River Monitoring Demonstration: Hosted by GroundTruth, this field trip took a group to Lions River to observe live demonstrations of water quality and quantity monitoring using advanced tools such as UAVs (drones), USVs (unmanned survey boats), and a suite of citizen science methods, including MiniSASS, clarity tubes, and velocity planks. The excursion showcased how high-tech innovation and community-driven monitoring can complement one another in managing freshwater resources.
uMkhomazi Upper Catchment: Michael chose to participate in this field trip, led by the Institute of Natural Resources’ Chief Scientist Jon McCosh and Scientist Zanele Makhaya, which examined grassland rehabilitation efforts aimed at reducing sediment mobilization at catchment scale. Erosion control project implementation and monitoring is conducted locally with participants who are trained as community scientists and restoration ecologists by the INR. Participants learned how erosion control strategies can extend the lifespan of proposed dams on the uMkhomazi River, while also considering the complex socio-ecological impacts of large infrastructure projects on local communities and landscapes.
