Join us as we celebrate the top 10 successes that made this year extraordinary:
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. And just this month, Dr. Fred Lubnow was honored with the NJ-AWRA Peter Homack Award for his outstanding contributions to the multi-disciplinary understanding and management of New Jersey’s water resources. These awards reflect the passion, innovation, and commitment to excellence that define Princeton Hydro.
We partnered with The Nature Conservancy to enhance accessibility and visitor experience at the South Cape May Meadows Preserve, a 200-acre haven of biodiversity that welcomes 90,000 visitors annually. The centerpiece of this collaboration is a new 2,675-foot elevated boardwalk and 480-square-foot viewing platform, designed to open access to previously unreachable areas and go beyond ADA standards to ensure visitors of all abilities can explore the preserve’s diverse landscape. Situated largely within freshwater wetlands, the project required innovative solutions to minimize impact on sensitive habitats. This effort highlights the importance of creating inclusive spaces that both protect and celebrate our natural world.
One of Princeton Hydro’s core offerings is grant writing for our nonprofit and government clients. This year alone, we landed nearly $1 million in grants for our clients for harmful algal bloom monitoring, habitat enhancement, water quality improvements, and planting native plants via the National Fish and Wildlife Foundation’s Delaware Watershed Conservation Fund and the Xerces Mid-Atlantic Pollinator Habitat Kit Planting Program.
This year, our talented team reached numerous applaud-worthy milestones, showcasing their dedication to advancing environmental science and sustainability. Amy McNamara became a Certified Professional in Erosion and Sediment Control (CPESC), highlighting her expertise in sustainable site design and regulatory compliance. Marissa Ciocco earned a Professional Engineer (PE) license in Connecticut, building on her existing licensure in Delaware. Chris Mikolajczyk CLM was appointed President-Elect of the Colorado Lake and Reservoir Management Association Board. Jesse Smith organized and implemented Flemington’s first-ever BioBlitz, a community-focused event that fostered a deeper connection to local biodiversity. Erin Bennett became a Notary Public in New Jersey and earned her Green Infrastructure Champions certification. Thomas Hopper achieved the Geographic Information Systems Professional (GISP®) certification, further elevating his contributions to geospatial analysis and restoration efforts. And, Matt Kreines earned his FAA Commercial Drone Pilot license.
We completed our first project in Colorado—a bathymetric assessment of the Fairplay Beach Reservoir, focused on mapping the reservoir’s underwater landscape to support ongoing conservation efforts. We are excited to bring our expertise in water resource management to new regions like Colorado and look forward to future opportunities to contribute to the preservation and enhancement of Colorado’s unique high-altitude aquatic environments. Stay tuned for more updates as we continue to explore new waters and chart new territories.
We made significant strides in advancing lake and watershed health through innovative initiatives. At Virginia’s Smith Mountain Lake, decades of historical data and cutting-edge research were leveraged to identify the drivers of harmful algal blooms and shape sustainable solutions. In New Jersey, a collaboration with the Mercer County Park Commission resulted in comprehensive lake and watershed management plans to address algal blooms and bolster ecological resilience across the park’s aquatic ecosystems. These projects highlight our unwavering commitment to protecting vital freshwater resources and fostering healthier ecosystems for future generations.
This year we welcomed Senior Wildlife Biologist Michael McGraw, CSE, QAWB, ACE, who joined our Regulatory Compliance & Wildlife Surveys team, bringing over 20 years of expertise in ecological assessments and wildlife surveys. Alexandra Garnett became a vital part of our Trenton office as an Administrative Assistant. Civil Engineer Ryan Krueger, PE, joined our Engineering Services team this month, and Eric Libis returned to our team as an Aquatics Specialist over the summer/fall. Kaitlyn Jones, who began as an intern, has now joined our Aquatics team permanently as a Staff Scientist! This summer, we also hosted four interns: Francisco Batz (Landscape Architecture), Jade Gallagher (Communications), Daniel Goll (Engineering), and Rachel Trokenheim (Aquatics).
We connected with industry professionals, communities, and stakeholders through a wide array of events, fostering collaboration, sustainability, and stewardship. In partnership with The Watershed Institute, we delivered impactful workshops, including the inaugural “Watershed Restoration Academy: Healthy Streams 101;” webinar sessions on daylighting streams and the conservation of American shad; and two education sessions at the 7th Annual Watershed Institute Conference. President Geoffrey Goll, PE traveled globally to participate in important river restoration and dam removal conversations, including the “Free Flow 2024 Conference” in The Netherlands, a river connectivity workshop in South Africa, and collaborations with Associação Natureza Portugal, a Portuguese non-profit NGO that works in association with World Wide Fund for Nature in Portugal. We also sponsored and presented at nationally prominent events, including the “NALMS International Symposium” in Lake Tahoe, CA; the “NYSFOLA Conference” in Lake George, NY; the “Harmful Algal Bloom Summit” in Portland, ME; and the “Delaware River Watershed Forum” in Bethlehem, PA, covering topics such as climate change impacts on lake ecology and green infrastructure stormwater management. Locally, we celebrated community and stewardship through events like the “Trenton River Days Fair,” Mercer County’s “Juneteenth Celebration,” and the New Jersey Highlands Council’s 20th anniversary, which highlighted collaborative Lake Hopatcong project successes. We also led two Facebook Live events: “Understanding and Managing Invasive Species in Your Backyard” and “Debunking Myths About Bats, Spiders & Snakes.” Through these efforts we deepened relationships with partners, advanced critical conversations, and inspired meaningful, sustainable change. These are just a few highlights from a truly impactful year!
