New Jersey Governor Mikie Sherrill signed Bill S3403/A4007 into law, requiring sellers to disclose the presence of dams on properties being sold in New Jersey along with information regarding the dams' condition, inspection history, hazard classification, and ownership obligations. The law is intended to improve transparency during real estate transactions and help buyers better understand the responsibilities that can accompany dam ownership before becoming contractually obligated to buy the property.
For many, a waterbody can be an attractive property asset that enhances aesthetics, recreation opportunities, and property value. However, what is not always apparent is that the waterbody may be maintained by a dam, and ownership of that dam comes with legal, financial, and regulatory responsibilities. Because dams are regulated infrastructure, depending on their size and hazard classification, owners may be responsible for routine inspections, maintenance, repairs, emergency planning, and ongoing compliance with state regulations. In some cases, property owners do not discover the full extent of those obligations until after a real estate transaction is complete, resulting in unexpected costs and liabilities.
"Dams are critical infrastructure, but they also have long-term responsibilities. Owners can face substantial costs associated with inspections, maintenance, rehabilitation, and regulatory compliance, and those obligations often transfer with the property purchase," explained Geoffrey M. Goll, PE, President of Princeton Hydro and NJ-licensed Professional Engineer. "This legislation helps ensure that prospective buyers understand the presence and condition of a dam so that they can evaluate those obligations upfront. Families and business owners can make informed investments while preventing unexpected liabilities, promoting public safety, and encouraging responsible stewardship of aging dam infrastructure across the state."
The passage of S3403/A4007 follows months of advocacy led by The Nature Conservancy in New Jersey, which first proposed the legislation and worked closely with lawmakers, stakeholders, and bipartisan supporters throughout the legislative process. Through testimony, coalition building, and sustained engagement, the organization helped elevate awareness of the challenges and costs associated with dam ownership and the importance of providing prospective property buyers with clear and timely information.
"No family should learn after purchasing a home that they have also assumed responsibility for a structure that could require extensive repairs or ongoing compliance costs," said Rebecca Hilbert, New Jersey Policy Associate at The Nature Conservancy. "By requiring transparency for buyers upfront, this legislation supports consumers, enhances public safety and helps ensure that dams affecting New Jersey's rivers and communities are responsibly managed."
Section 1 of the New Jersey Dam Disclosure Law states, "A seller of real property located in this State shall disclose, on the property condition disclosure statement, whether a dam is located within the boundaries of the property and any actual knowledge of the seller concerning the dam, as required pursuant to this section, to the purchaser before the purchaser becomes obligated under any contract for the purchase of the property." The law also adds specific dam-related questions to the property condition disclosure statement, including:
Additionally, the law directs prospective buyers to New Jersey Department of Environmental Protection (NJDEP) resources regarding dam ownership responsibilities, dam removal, and hazard classifications to gain a better understanding of the implications of dam ownership before becoming contractually obligated or completing the sale transaction.
The law serves a broader public safety purpose. Better informed ownership can encourage compliance with dam safety requirements, timely maintenance and repairs, and informed decision-making regarding rehabilitation, dam removal, and river restoration.
These responsibilities are not insignificant. Under New Jersey's Safe Dam Act and Dam Safety Standards (N.J.A.C. 7:20), regulated dams must be inspected by a qualified New Jersey-licensed Professional Engineer every two to four years, depending on the dam's hazard classification. Regulated dam owners are also required to maintain an Operation and Maintenance Manual, while Hazard Class I and II dams must have a NJDEP-approved Emergency Action Plan in place. A regulated dam is generally defined as an artificial dike, levee, or barrier that raises the waters of a stream more than five feet above the usual mean low water height. Many property owners may be unaware that these requirements apply to a structure on their property until they begin exploring its regulatory status or ownership obligations, or receive a compliance letter from NJDEP.
These requirements exist to protect people, property, and the environment from the consequences of dam failures. When dams are not properly maintained, the impacts can extend far beyond the property boundary, potentially resulting in downstream flooding, property damage, environmental degradation, impacts to wildlife habitat, and, in the most severe cases, loss of life. By increasing awareness of dam ownership responsibilities before a property changes hands, the new law can help support safer, more proactive management of New Jersey's aging dam infrastructure while reducing the likelihood of unexpected costs and obligations for future owners.
In a press release from The Nature Conservancy the organization stated, "The Nature Conservancy supported the legislation because dams can have lasting impacts on public safety, local communities and the health of New Jersey's waterways. Ensuring property owners understand their responsibilities is an important step toward informed stewardship of dams that affect both people and nature."
We applaud The Nature Conservancy for spearheading this effort and building the bipartisan support needed to move the legislation from concept to law. We also thank Governor Sherrill, Senator John Burzichelli, Assemblyman Dave Bailey, Assemblyman Sterley S. Stanley, and the many legislators who recognized the importance of greater transparency for New Jersey homebuyers and businesses.

Each July, Lakes Appreciation Month invites us to reconnect with one of our most valuable natural resources: our lakes. Since 1998, the North American Lake Management Society (NALMS) has led this initiative to raise awareness about the ecological, recreational, and community benefits lakes provide, while encouraging people to take an active role in protecting them. This year, we’re encouraging you to take your appreciation further by learning, participating, and making meaningful connections with your local lake. Here are four impactful ways to celebrate:
No matter how well you know your local lake, there is always something new to discover. Visit at a different time of day, explore a new access point, or try an activity you've never done before, like birding, early morning paddling, or shoreline photography.
As you spend time on the water or along the shore, take note of the details. Look for changes in water clarity, plant growth, wildlife activity, and seasonal shifts. These small observations can deepen your appreciation and help you better understand how your lake functions. If something doesn't look right, like signs of a harmful algal bloom, the presence of invasive aquatic species, or other water quality concerns, take note and share what you see. Reporting observations to your local lake association or through tools like the bloomWatch app can support monitoring efforts and help protect your lake.
Take your lake visit one step further by joining the annual Secchi Dip-In. This long-running citizen science effort invites volunteers across North America to measure water clarity using a simple Secchi disk. The data collected helps scientists and lake managers track water quality trends over time. Participation is simple and meaningful, and every reading contributes to a larger understanding of lake health.
If you are new to using a Secchi disk, watch our step-by-step instructional video to learn how to take accurate measurements:
Lakes bring people together and create lasting memories. This month, take the opportunity to share your connection to your favorite lake and inspire others to get involved. Join the NALMS #LakesAppreciation Challenge by posting photos or videos that capture your experience. Capture a quiet sunrise, a family outing, or a day spent volunteering and show others what makes your lake special.
Looking for more ways to tell your lake story? Try one of these ideas:
When you share, be sure to include the lake name and the hashtag #LakesAppreciation to connect with the broader celebration.
You don't need to make a big commitment to make a meaningful difference. Small, consistent actions can have a lasting impact on lake health over time. Here are a few simple ways to give back:
Communities across the country are working together to protect and restore their lakes. Your efforts, no matter how small, play an important role in that collective impact.
Lakes Appreciation Month is just the starting point. The actions you take now can help protect and improve your lake all year long. Keep exploring, stay engaged, and continue being a voice for the waters you value. For more ideas and resources, visit NALMS.org.

When a dam is removed, what happens to all the sediment that has built up behind it?
That question was the focus of a recent Dam Busters webinar led by Geoffrey M. Goll, PE, President of Princeton Hydro and an internationally recognized expert in dam removal and river restoration.
During the session, Geoff shared insights on how sediment behaves during dam removal projects, how it accumulates behind dams, and how different materials such as sand, silt, and organic matter respond once the dam is removed. He also discussed the methods practitioners use to estimate how much sediment is likely to move, how quickly it will travel, and the risks it may pose downstream, along with the practical decisions project teams face, including when to rely on natural processes, when intervention is needed, and how to design a strategy that balances ecological benefits, cost, and potential impacts.
During the webinar, Geoff highlighted a real-world example of a dam removal project that required careful sediment management: the Paulina Lake Dam removal on the Paulins Kill River in New Jersey. For this project, the team implemented a phased dam breach, gradually lowering water levels to control the release of sediment and allow the river to begin forming its new channel. A portion of the sediment, particularly the highly organic material near the dam, was actively removed to prevent downstream impacts, while the rest was allowed to mobilize naturally.

The Town of Greenwich, Connecticut worked with Princeton Hydro, in partnership with Ecopolitan Design and BRS, to assess vulnerabilities to coastal flooding and sea level rise and develop a comprehensive coastal resilience strategy. With 27 miles of shoreline along Long Island Sound and numerous critical assets in low-lying areas, the Town sought to better understand climate-related risks and establish priorities for adaptation.
As part of the Greenwich Coastal Resiliency Assessment and Plan, Princeton Hydro developed a StoryMap that translates technical analyses into a detailed, accessible overview of the Town’s vulnerability to coastal flooding and sea level rise, including impacts to public facilities, infrastructure, and areas served by on-site septic systems. Users can explore sea level rise risk assessments, projected flooding scenarios, tidal pond evaluations, recommended resilience strategies, and community perspectives, along with helpful resources. By presenting complex climate data in a clear and interactive format, the StoryMap serves as a planning resource and increases awareness of coastal risks and resilience strategies as Greenwich prepares for future conditions.
To support the development of the 2025 D&R Canal Master Plan update, Princeton Hydro partnered with Clarke Caton Hintz to create a comprehensive geospatial dataset that reflects current physical, environmental, and social conditions through the park and surrounding region. The previous Master Plan, last updated in 1989, predated many of the advancements in geospatial data that are now available to inform planning and decision-making.
Princeton Hydro curated a selection of datasets covering a wide range of topics, including land use and development, topography, hydrology and water resource protection, flood risk, threatened and endangered species, demographics, and environmental justice, creating a detailed and consistent data foundation for the master planning process. These datasets were integrated into an ESRI geodatabase and made accessible through an interactive, user-friendly dashboard. Users can refine their exploration by selecting specific geographies, including Delaware and Raritan Canal Commission review zones, counties, and municipalities. This flexibility allows planners and stakeholders to better understand spatial patterns and relationships across the region, supporting more informed, data-driven decision-making.
Across each of these projects, StoryMaps serve as a bridge between technical analysis and public understanding. By turning complex information into interactive experiences, StoryMaps help support informed decisions and build stronger connections to the environment.
Welcome to our “A Day in the Life” blog series, where we highlight the expertise and experiences of our team members as they work to advance Princeton Hydro’s mission of improving ecosystems, quality of life, and communities. In this edition, we take to the skies with Ryan Eno, EIT, a Staff Engineer in our Geosciences group and an FAA-certified drone operator whose work blends engineering, technology, and creativity to support our projects.
Ryan’s role offers a unique perspective (quite literally) on how drones are shaping environmental restoration and monitoring efforts. Let’s get a bird’s-eye view of a day in the life of a Princeton Hydro drone operator:
Ryan’s day often starts well before he steps onto a project site. Drone operation requires careful pre-flight planning, especially when working across varied landscapes and within regulated airspace. Ryan uses mapping tools and satellite imagery to identify safe launch points and ensure he can maintain a clear line of sight with the drone throughout the flight, a requirement set by the FAA. “For any project, the first step is checking airspace restrictions,” Ryan explains. “There are limitations around government facilities, state lands, and, without much advanced notice, no-fly zones that can be implemented around high-profile locations.”
Operating drones professionally comes with even more regulatory and logistical considerations. “There are a lot of airspace restrictions to keep track of,” Ryan explains. “For example, drones cannot be flown in New Jersey State Parks without permission, and temporary flight restrictions can change depending on circumstances.” Balancing these requirements with field conditions requires flexibility, attention to detail, and constant awareness. “It is all about planning, safety, and making sure we are operating responsibly and within the law.”
Once on site, Ryan is focused on safety, positioning, and capturing the right visuals. “In many cases, just getting the drone to a safe takeoff location is the first challenge,” he says. “You need a clear opening in the tree canopy and enough space to launch and land safely.”
Operating in natural environments introduces additional complexity. Dense vegetation, uneven terrain, and changing weather conditions require constant awareness and adaptability. “Even though our drone has obstacle-avoidance sensors, they are not perfect, especially with moving tree branches,” Ryan notes. “I have to stay focused and anticipate how the drone will move through the environment.”
Ryan also remains mindful of wildlife and ecological sensitivity during drone operation, “Drones usually fly high enough as to not disturb animals on the ground, but we always pay close attention to birds, especially during nesting seasons."
One of the most valuable aspects of Ryan’s work is documenting the transformation of our project sites. Using Princeton Hydro’s DJI Phantom 4 Pro V2, a high-resolution aerial photography drone, Ryan captures imagery that helps tell the story of a project from start to finish. “I really enjoy projects where I can capture a site before and after construction,” he says. “The drone really helps tell the story and provide a complete perspective. It captures the entire transformation in a single frame, which is much harder to convey from the ground.”
The aerial drone images and videos are often used to:
This type of imagery is especially powerful for Princeton Hydro’s ecosystem restoration projects. A recent example is Princeton Hydro’s work on the Paulina Lake Dam removal and Paulins Kill River restoration in Warren County, New Jersey. Led by The Nature Conservancy and funded by the NJDEP Division of Fish and Wildlife, the project reconnected 7.6 miles of river habitat, building on an additional 10 miles restored through the earlier Columbia Lake Dam removal. From the ground, it can be challenging to grasp the full extent of change following a dam removal. Aerial imagery captured before, during, and after construction provides a comprehensive view of how the river system responds. When the site was revisited a year later, the transformation was clear. The river had re-established its natural flow and reconnected habitats that had been fragmented for generations.
Drone footage captured by The Nature Conservancy, Renova Environmental Company, and Princeton Hydro played a key role in documenting this process. Drawing on aerial imagery collected before demolition and throughout construction, the resulting video illustrates the full progression of the project, from initial notching to full restoration. It highlights how careful sequencing, sediment management, and adaptive design allow rivers to recover rapidly once barriers are removed.
Drones at Princeton Hydro are used in a wide range of applications. “They allow us to access remote areas and collect data much faster than traditional methods,” Ryan says. “Applications like wildlife surveys and large-scale monitoring are being transformed by drone technology." Drones equipped with multispectral, thermal, and LiDAR sensors can generate detailed datasets that support habitat mapping, vegetation analysis, and long-term monitoring. These tools help project teams better understand site conditions, identify degraded areas, measure restoration success over time, and conduct comprehensive scientific studies.
A notable example is Princeton Hydro’s involvement in a groundbreaking drone-based research initiative to monitor harmful algal blooms (HABs) in the Delaware River Watershed. This effort, done in partnership with Friends of Hopewell Valley Open Space with funding from the National Fish and Wildlife Foundation's (NFWF) Delaware Watershed Conservation Fund (DWCF), in partnership with the U.S. Fish & Wildlife Service, 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.
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. Drone flights and data collection began in Fall 2025 and will continue through 2026, with a final report anticipated in 2027. Click here to read more about this initiative.

Gloucester County’s Scotland Run Nature Preserve is a place where education, recreation, and ecological diversity come together. As the largest park in the county system, spanning more than 1,300 acres, Scotland Run offers visitors a chance to explore a wide range of habitats including woodlands, open fields, streams, and lakeside environments. Situated along the boundary of New Jersey’s Inner and Outer Coastal Plains, the park reflects features of both Piedmont and Pine Barrens landscapes, supporting a remarkable variety of wildlife.
At the center of the park is Wilson Lake, an 80-acre man-made lake created by a historic dam built for Fries Mill on Scotland Run. Today, the lake provides passive recreation opportunities such as fishing, canoeing, and nature observation. An ADA-accessible fishing pier near the boat launch ensures that these experiences are available to everyone. The park is also highly family friendly, with maintained walking trails, picnic areas, a playground, restrooms, and a Nature Center that serves as a hub for learning and discovery.
This winter, the Nature Center hosted Nature at Night, a popular exploration series that invites community members to engage with the natural world through hands-on presentations led by environmental professionals. Held on the 3rd Thursday of the month from January to April, topics throughout the series included mammals, fossils, insects, birds, reptiles, and amphibians, offering something for nature lovers of all interests.
Princeton Hydro Senior Wildlife Biologist Mike McGraw, CSE, QAWB, ACE led an engaging and energetic program focused on reptile and amphibian evolution, morphological adaptations, and the incredible diversity found right here in New Jersey. To bring these concepts to life, he introduced a mix of his personal pets and rescue animals, creating meaningful, up-close learning experiences with the audience members.
The turnout was outstanding, with a packed room of participants ranging in age from 4 to 74. Guests were curious and enthusiastic, asking thoughtful questions and sharing their own stories, which helped create an inclusive and lively learning environment. It was clear that hands-on outreach like this sparks curiosity and builds lasting connections to local ecosystems.
This year marked Mike’s fifth consecutive year leading a Nature at Night session at Scotland Run, a milestone that only begins to reflect his commitment to environmental education. Mike is deeply involved in a wide range of educational and outreach programs, sharing his passion and expertise with audiences of all ages. His enthusiasm is contagious, his knowledge runs deep, and his ability to connect people to the natural world makes every program memorable. Educators like Mike play a vital role in inspiring curiosity, fostering stewardship, and strengthening human connection to the natural world. Click here to learn more about Mike.
Experiences like these are especially important for young people, helping them build curiosity, confidence, and a lasting appreciation for the landscapes around them. That same approach carries through other interactive, place-based learning efforts at Princeton Hydro, including recent work with local students that explores how science, community, and the built and natural environment intersect.
Scotland Run Nature Preserve provides a welcoming space for learning and discovery, where thoughtful programs help spark interest in the natural world for visitors of all ages. To learn more about their Nature at Night series and other outdoor education opportunities, click here.
