In this edition, we follow Casey Pantaleo, PE, a licensed Professional Engineer and Senior Project Manager on the Engineering Services team as he performs one of his highly specialized roles: dam inspection. Casey meets the New Jersey Department of Environmental Protection (NJDEP)’s criteria for a “qualified engineer,” meaning he is licensed in New Jersey, has more than a decade of relevant experience in dam design, construction, operation, and evaluation, and possesses a deep understanding of the potential causes and consequences of dam failures. He routinely conducts detailed inspections to help ensure the safety and stability of dams across New Jersey and throughout the Northeast. These structures, which play crucial roles in flood control, water supply, and recreation, require routine maintenance and monitoring to protect downstream communities and preserve infrastructure integrity. Spend a day with Casey and you’ll quickly realize that dam safety inspection is anything but routine—it’s equal parts technical expertise, historical context, and regulatory navigation, along with a good pair of waterproof boots. Inspection, Planning & Records Review Before heading into the field, the inspection process begins with reviewing the dam’s existing documentation—and the scope of that review depends on the type of inspection being conducted. For a Formal Inspection, the process requires an in-depth review of all available records on the dam. This typically takes place in person at the NJDEP Bureau of Dam Safety office and should be completed prior to the field visit. For a Regular Inspection, the inspector reviews the most recent inspection report, the dam’s Emergency Action Plan (EAP), and the Operation and Maintenance (O&M) Manual. This step is essential for understanding the dam’s history, known concerns, and any previous recommendations or repairs. Both inspection types involve a detailed on-site visual examination of the dam. The Bureau of Dam Safety provides a standardized inspection checklist that guides this process. The checklist includes specific criteria for earthen embankments, concrete/masonry dams, and their spillway structures. “For earthen embankment dams, we assess the overall alignment, crest, upstream and downstream slopes, and dam abutments,” explains Casey. “We’re looking for signs of settlement, depressions, slope instability, seepage, and other indicators of distress.” For concrete dams, inspectors evaluate the upstream and downstream faces, crest, foundation, abutments, and any interior galleries. The key concerns here are material condition, cracking, seepage, and structural movement. The spillway—often inspected last—requires identification of all structures associated with overflow and release. Depending on the dam’s configuration, this may include primary, secondary, or emergency spillways. Components typically observed include:

“For earthen embankment dams, we assess the overall alignment, crest, upstream and downstream slopes, and dam abutments,” explains Casey. “We’re looking for signs of settlement, depressions, slope instability, seepage, and other indicators of distress.”
For concrete dams, inspectors evaluate the upstream and downstream faces, crest, foundation, abutments, and any interior galleries. The key concerns here are material condition, cracking, seepage, and structural movement.
The spillway—often inspected last—requires identification of all structures associated with overflow and release. Depending on the dam’s configuration, this may include primary, secondary, or emergency spillways.
Components typically observed include:
“Every dam is different,” Casey adds. “Not all structures have every component listed on the checklist, so part of our job is tailoring the inspection to the specific site configuration.”
The Formal Inspections checklist also includes a review and description of previous engineering studies and analyses, which ensures the dam continues to meet regulatory requirements. These formal evaluations are required every six years for Class I (high hazard) dams, and every ten years for Class II (significant hazard) dams.
All findings from both the field inspection and records review are compiled into a detailed inspection report, which includes photographic documentation and a formal condition rating:
The report also outlines a compliance schedule, proposing timelines for maintenance work, additional studies, or other corrective actions. Once complete, the report is signed and sealed by a licensed Professional Engineer (PE) and submitted to both the client and the Bureau of Dam Safety.
With the planning and records review process complete, Casey prepares for the physical site visit. Dam inspections often require a full day in the field, so preparation is key.
The first step before heading to the site is preparing an Activity Hazards Analysis (AHA). This document outlines the specific activities planned during the inspection, identifies potential hazards associated with each task, and defines the control measures used to eliminate or reduce risk. The AHA also includes the location of the nearest hospital or urgent care facility in case of injury.
Common hazards associated with dam inspections include slips, trips, and falls, insect nests, poison ivy, working near water, and occasionally, working on or near active roadways. Seasonal risks are also considered—such as the potential for heat illnesses during the summer months or cold-related injuries in the winter.
With safety protocols in place, Casey reviews the inspection schedule, checks the weather forecast, prints site maps, and gathers all the necessary personal protective equipment—waders, hard hat, and high-visibility vest—along with essential tools like a tape measure, measuring wheel, tile probe, field notebook, and camera.
Each tool plays a specific role. The tape measure is used for small-scale assessments, such as measuring cracks or depressions. The measuring wheel helps determine distances between notable features onsite. The tile probe allows Casey to gauge the density and consistency of embankment soils and to investigate for voids in concrete structures. It also comes in handy for checking the depth of animal burrows or the extent of subsurface voids within the dam.
“Having the right measuring tools is absolutely essential,” Casey explains. “We aim to collect the most detailed measurements possible so future inspections can determine whether a condition is getting worse. We also try to anticipate every potential hazard and ensure we have everything we might need before leaving the office. Sometimes we’re hiking through thick brush to reach a spillway or crawling into an outlet conduit—so having a solid plan and the right gear isn’t just helpful, it’s critical.”
Today’s inspection takes place at Assunpink Dam #6, an earth embankment dam located in Robbinsville Township, Mercer County, New Jersey. Built in 1975, the dam is part of a flood control system designed to reduce risks along Assunpink Creek. The structure stands 31 feet high and stretches 2,500 feet long, with a total storage capacity of 12,653 acre-feet. It features a concrete spillway and an upstream water control structure. Owned by the New Jersey Division of Fish & Wildlife, the dam is regulated by the state and classified as a high-hazard structure—meaning its failure could result in significant downstream impacts, making regular inspections essential.
To begin the inspection, Casey walks the full length of the embankment, conducting a detailed visual assessment. He looks for telltale warning signs: animal burrows, seepage, erosion, settlement, slope instability, and woody vegetation that could damage the dam face or block visibility during future inspections. One of the most common and problematic issues he encounters is overgrown vegetation, which can significantly hinder the ability to properly evaluate the structure. Keeping the dam clear is critical for spotting early warning signs and maintaining long-term safety.
“Each dam tells its own story,” Casey explains. “Some may show signs of movement, others are perfectly stable. One site might have seepage issues, while another remains completely dry. It all depends on the structure and how it’s aged.”
He carefully inspects the embankment and associated structures for signs of movement, depressions, sloughing, cracking, and uncontrolled seepage—any of which could indicate an underlying issue that requires remediation.
“We follow a standard checklist during every inspection, but each dam is unique,” he adds. “Part of the job is understanding how these systems were built—some decades or even over a century ago—and how they’ve changed over time.”
After completing the full inspection—including the downstream toe, abutments, and emergency spillway—Casey wraps up his field notes, double-checks measurements, and ensures that all required photos have been captured. Before leaving the site, he often debriefs with the site representative, noting any immediate maintenance needs and outlining the next steps in the reporting process.
Back in the office, Casey begins transcribing his notes into a formal inspection report. He uploads and labels photos, updates GIS data where applicable, and reviews the dam’s historical inspection records to identify long-term trends or recurring issues. These records often help tell a broader story about the structure’s condition over time—highlighting vegetation growth, erosion patterns, or the effectiveness of past repairs.
Safety is always the top priority. If the inspection reveals anything that could pose an immediate risk to people or property downstream—such as uncontrolled seepage, excessive settlement, or slope instability—Casey contacts the dam owner and the NJDEP right away to recommend prompt action. Beyond urgent concerns, the inspection report also includes recommendations for routine maintenance and identifies any outdated analyses or studies that should be updated.
In many cases, the findings involve standard upkeep: clearing overgrown vegetation, reseeding disturbed areas, monitoring minor cracks or depressions, or maintaining access to critical features. One frequently emphasized point is the importance of operating the dam’s low-level outlet—if one is present—on a regular basis. Doing so helps ensure the outlet remains free of sediment or debris and functions properly in an emergency when water levels need to be lowered quickly.
New Jersey is home to more than 1,700 dams, according to data from NJDEP Bureau of Dam Safety. These regulated structures range from low-hazard to high-hazard classifications—the latter being dams whose failure could result in significant property damage or loss of life. Regular inspections are not only a regulatory requirement, but a frontline defense against catastrophic failure. They help identify small problems before they become serious, support safe operation, and guide critical maintenance and repair decisions that protect both people and ecosystems.
“Dam inspection doesn’t always get the spotlight, but it’s essential,” says Casey. “We’re helping communities prevent disasters before they happen by keeping a close eye on structures that quietly serve very big purposes.”

On April 12, Princeton Hydro President Geoffrey M. Goll, PE along with the Lower Makefield Township Environmental Advisory Council led a free community workshop on how to build a rain garden. As part of the Advisory Council’s Environmental Lecture Series, Geoffrey demonstrated the environmental benefits of rain gardens and provided practical tips on how to build one.
The New York State Federation of Lake Associations (NYSFOLA) 42nd Annual Conference was held on May 2 and 3 at the the Fort William Henry Hotel and Conference Center in Lake George. In the theme “Back to the Future: Old Lake Issues and New Solutions,” the event featured panel discussions, workshops, networking opportunities, and an exhibitor hall. Princeton Hydro sponsored, exhibited and led two workshops: Chris Mikolajczyk, CLM, Senior Manager of Aquatics, presented “Old Lake Issues? The EPA National Lakes Assessment (2000s) and Funding New Experimental Solutions.” And, Dr. Fred Lubnow, Senior Technical Director of Ecological Services, presented “Internal Loading: Updated Solutions for an Old and Increasing Problem for Lakes.”
Earlier this month, lake advocates, environmental professionals, researchers, and community leaders gathered for the 42nd Annual New York State Federation of Lake Associations (NYSFOLA) Conference. Held at the Fort William Henry Hotel and Conference Center, overlooking beautiful Lake George, the event brought together individuals from across the region to reexamine longstanding lake and watershed challenges through the lens of innovation, collaboration, and science.
With this year’s theme, “Back to the Future: Old Lake Issues and New Solutions,” the conference emphasized how new policies, technologies, and strategies can be applied to address persistent water quality issues. The two-day program featured a robust lineup of educational sessions, workshops, an exhibitor hall, and networking opportunities, all designed to inspire fresh ideas and collective action.
The conference kicked-off with a keynote from Greg Michel, Executive Director of Onondaga Earth Corps, a youth and community development organization headquartered in Syracuse, New York that engages young adults in environmental service projects. Michel and his team inspired attendees with stories of empowering the next generation of conservationists while tackling real-world ecological needs.
As a proud sponsor, event exhibitor, and long-time member of NYSFOLA, Princeton Hydro led two educational workshops, both focused on bringing data-driven insights and practical funding strategies to lake communities.
Chris L. Mikolajczyk, CLM, Senior Manager of Aquatics shared insights from the most recent EPA’s National Lakes Assessment (NLA), which offers a statistically valid snapshot of lake health across the US. Using data from the NLA’s recurring five-year surveys, he illustrated how the findings help identify ecological conditions, long-term trends, and stressors impacting our lakes.
While the Clean Lakes Program (Section 314 of the Clean Water Act) once provided federal funding for in-lake restoration, it hasn’t been funded since 1995. Chris emphasized how large-scale assessments like the NLA can still play a crucial role in shaping effective lake management strategies and strengthening funding proposals. He spotlighted current funding opportunities from the New Jersey Highlands Council, the National Fish and Wildlife Foundation, and the U.S. Army Corps of Engineers Environmental Research and Development Center. Through real-world case studies, he illustrated how data-driven planning can translate into on-the-ground results for lake restoration and protection.
Dr. Fred Lubnow, Senior Technical Director of Ecological Services, tackled internal phosphorus loading—a growing concern for lakes already struggling with nutrient enrichment and harmful algal blooms (HABs). Unlike external sources of pollution, internal loading arises from within the lake itself, particularly in sediment layers that continue to release nutrients long after the original source has been addressed.
Fred provided detailed case studies from lakes across the Northeast and Mid-Atlantic, including Lake Mohawk and Lake Hopatcong in New Jersey, Harveys Lake in Pennsylvania, and Smith Mountain Lake in Virginia. He demonstrated how targeted in-lake and watershed strategies—when backed by proper assessment and data—can successfully reduce internal phosphorus levels and improve long-term lake health.
Thank you to NYSFOLA for another outstanding conference and the opportunity to support the mission of protecting New York’s lakes. Princeton Hydro is proud to be part of this dynamic community advancing innovative, science-based solutions. We enjoyed the engaging conversations, insightful presentations, and opportunities to collaborate with lake professionals from across the region — and we had a blast at trivia night!
On April 9, experts and stakeholders from across the country gathered virtually for the New Jersey Department of Environmental Protection’s (NJDEP) 6th Annual Harmful Algal Bloom (HAB) Summit. Held via Microsoft Teams and free to attend, this year’s summit embraced the theme “Kicking the HAB-it Together: Collaborating to Get Ahead of HABs”—a fitting reflection of the event’s focus on moving away from crisis-driven responses and toward proactive, long-term solutions for managing HABs.
The summit brought together a diverse audience of local, state, and federal government representatives, environmental commissions, watershed associations, nonprofits, academic researchers, lake management professionals, and community members united by a shared goal: to better understand, prevent, and manage the impacts of HABs. With presentations spanning public health, policy, science, and on-the-ground solutions, the program set the stage for a day of insightful discussion and knowledge-sharing.
The day kicked off with opening remarks and presentations from NJDEP representatives and the Montgomery Township Health Department, who provided updates on state-level HAB response efforts and local public health perspectives. The morning session also featured a technical keynote address from Dr. Wayne Carmichael, Professor Emeritus at Wright State University and a nationally recognized pioneer in HAB research. Dr. Carmichael offered a comprehensive national overview of the current HAB landscape, emerging threats, and the evolving science behind bloom detection, health risk assessment, and mitigation strategies. His presentation underscored the importance of cross-sector collaboration in tackling this growing environmental challenge.
In the afternoon, the focus shifted to collaboration and preparedness. A panel discussion titled “Getting Ahead of the Crisis: Prevention vs. Response” included a range of voices, including NJDEP leadership, municipal representatives, and advocacy groups like The Watershed Institute. Panelists discussed how coordinated efforts, regulatory tools, and community engagement can help prevent the conditions that lead to HABs, rather than merely responding after blooms occur.
The final portion of the summit highlighted innovative management strategies. Presentations covered topics like choosing practical solutions for HABs and restoration case studies. Princeton Hydro’s own Pat Rose, Aquatics Project Manager and Environmental Scientist, was among the expert speakers. Pat presented on a cutting-edge research and development initiative funded by the U.S. Army Corps of Engineers' Engineer Research and Development Center (ERDC). His talk explored both proactive and reactive treatment strategies designed to control near-shore HABs at Lake Hopatcong, New Jersey's largest lake, in a cost-effective and sustainable manner.
If you weren’t able to attend the summit live, don’t worry—you can now watch the full recording on the NJDEP YouTube channel:
HABs are rapid, large overgrowths of cyanobacteria. Cyanobacteria, also known as blue-green algae, aren’t actually algae, they are prokaryotes, single-celled aquatic organisms that are closely related to bacteria and can photosynthesize like algae. These microorganisms are a natural part of aquatic ecosystems, but, under the right conditions (e.g., heavy rains followed by hot, sunny days), these organisms can rapidly increase to form HABs. Climate change is leading to more frequent, more intense rainstorms that drive run-off pollutants into waterways, coupled with more hot days that increase the water temperature, creating the ideal environment for HABs to proliferate. In recent years, HABs have begun to appear in more places, earlier in the summer.
The New Jersey Governor’s HABs Initiative was launched in 2019 after lakes throughout NJ (and the entire Continental U.S.) suffered from HAB outbreaks, which caused local and county health agencies to close off all beaches and issue advisories. These unprecedented conditions had significant negative impacts on lake-related ecological, recreational, and economic resources. The Governor’s initiative designated $13 million in funding to local communities for HABs reduction/prevention; established the HABs expert team, which includes Princeton Hydro Senior Technical Director, Ecological Services Dr. Fred Lubnow; and coordinated annual HABs summits in order to encourage continued community education and discussion.

The Bucks County Conservation District, in collaboration with Bucks County Planning Commission and Princeton Hydro, has launched an interactive ArcGIS StoryMap showcasing the Lake Luxembourg Conservation Pool Restoration Project. This engaging web application weaves together interactive storytelling, multimedia, charts, diagrams, and dynamic web maps to provide an in-depth look at the decade-long journey to restore Lake Luxembourg's Conservation Pool.
Designed as a publicly accessible resource, the StoryMap allows users to explore project details in an intuitive, interactive format—zooming and panning through specific project areas, viewing site attributes, and navigating restoration initiatives without the need for specialized GIS software or training. Its goal is to connect the community with its watershed, showcase the significance of restoration efforts, and inspire environmental stewardship.
Let’s take a closer look at the restoration project and how the StoryMap brings it to life.
In the summer of 2024, the Bucks County Conservation District in collaboration with Bucks County government completed the Conservation Pool Restoration Project, the culmination of a decade-long effort to improve water quality in the Core Creek watershed.
The Conservation Pool is an upstream section of Lake Luxembourg, a 174-acre reservoir that serves as the final major stop for Core Creek before it flows into Neshaminy Creek. Located northeast of the Woodbourne Road bridge, the Pool accounts for one-tenth of the lake’s total area. Surrounded by wetlands, forests, and agricultural fields, it also receives water from two smaller tributaries in addition to Core Creek.
The project, with engineering and design beginning in 2016, focused on enhancing the Conservation Pool’s ability to filter pollutants by reducing sediment and nutrient buildup. To achieve this, the project team created a sediment forebay—an upstream settling basin designed to capture sediment before it enters the main lake—by dredging 15,000 cubic yards of phosphorus-rich sediment from the Pool’s upstream section. Native vegetation was planted along the shallow banks to stabilize the shoreline, filter excess phosphorus, and establish an emergent wetland system that supports native wildlife.
Over the course of a month, approximately 36,000 live plugs were planted at the Lake Luxembourg Conservation Pool. Wooden stakes, construction fencing, and twine was installed around planting areas to deter geese from eating the young plants:
This long-term management approach enhances pollution control in the watershed while ensuring future maintenance and sediment removal can be carried out efficiently. Princeton Hydro continues to work with watershed stakeholders to improve Lake Luxembourg’s water quality, including partnering with BCCD to reassess and update stabilization practices in areas affected by the changing climate and invasive species.
Now, thanks to the ArcGIS StoryMap, the entire restoration process can be explored in an interactive and engaging way!

Soil analysis is an essential part of environmental science, providing key insights into land composition, hydrology, and ecological health. In this installment of our "Field Notes" blog series, where we explore essential tools used by Princeton Hydro’s team, we take a deep dive into the Munsell Soil Color Chart—a standardized system that allows professionals to classify and communicate soil characteristics with accuracy. This tool is particularly useful in wetland delineations, where soil color helps determine whether an area meets the criteria for wetland classification.
What if the ground beneath your feet could tell a story? Soil isn’t just dirt—it’s a dynamic, living record of the landscape’s history, composition, and ability to sustain life. One of the most revealing clues in soil analysis is color, which reflects key properties such as drainage, organic matter content, and oxidation levels.
One key application of the Munsell Soil Color Chart is in wetland delineation, a process that determines whether a particular area meets the hydrologic, vegetative, and soil criteria for wetland classification. Soil scientists use an auger to extract a sample from the ground, where the first 6 to 12 inches, also known as the upper part, of the soil profile is the most important for determining whether the soils are hydric.
Hydric soils are defined as those that form under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part of the soil. The landscape of the site also plays a crucial role in hydric soil development. Factors such as hydrology, slope, landform, soil materials, and vegetation influence how these conditions emerge. These environmental factors trigger biogeochemical processes that lead to the development of distinct hydric soil indicators, including:
Once a scientist identifies a hydric soil, they refer to the Munsell Soil Color Chart to classify its matrix color and any hydric soil indicators present. This classification helps determine whether the area qualifies as a wetland under regulatory guidelines.
Before conducting a wetland delineation, Princeton Hydro Environmental Scientist Ivy Babson, PWS, first determines which United States Army Corps of Engineers (USACE) Wetland Delineation Region her site is located in—an essential step for ensuring proper classification. For a recent wetland delineation, Ivy identified her site as being within the Northcentral and Northeast Region and conducted pre-delineation research, which revealed that the area was characterized by shallow bedrock and exposed boulders.
Upon arriving at the site, Ivy observed that the wetland had formed within an old basin. The sloped basin floor supported hydrophytic vegetation, including cattails, sedges, and rushes, with visible drainage patterns and hummock-hollow microtopography indicating prolonged wet conditions.
Once Ivy selected a suitable location for a soil boring, she used a Dutch auger to extract a soil sample. The first 6 inches of the profile revealed very dark mineral soils with a high amount of decomposed organic material. Using the Munsell Soil Color Chart, she classified the sample as 10YR 2/1—a black, saturated mucky loam.
She also identified strong brown (7.5YR 4/6) redoximorphic features along plant root pore linings, indicating iron reduction due to prolonged saturation:
The next six inches of soil maintained a similar composition before transitioning at nine inches to a gray clay layer (10YR 5/1) with many yellowish-brown (10YR 5/6) redoximorphic features occurring as reduced iron soft masses, another clear indicator of prolonged saturation:
By 15 inches, Ivy hit bedrock, confirming that groundwater was perched above the rock layer, creating the saturated conditions necessary for hydric soil development.
To determine whether the site met wetland criteria, Ivy referred to the USACE’s Regional Supplement to the Wetland Delineation Manual, which provides region-specific hydric soil indicators. She identified several key indicators in her soil profile:
The combination of these four hydric soil indicators proves that the area is a wetland and is subject to conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part of the soil—a conclusion supported by the area's shallow bedrock, high water table, and saturated soil conditions.
Ivy draws a unique parallel between soil analysis and Vincent van Gogh’s Starry Night, transforming scientific observation into an artistic analogy:
"Looking at the Starry Night painting, my eyes are immediately drawn to the bright yellow stars and white moon against the dark blue night sky. In soil analysis, the dark blue sky represents the matrix of the soil, while the bright stars and moon resemble hydric soil indicators that ‘pop’ out. The streaking cypress tree in the painting? That’s like a redoximorphic concentration of manganese forming around a plant root. Just as these elements make Van Gogh’s painting unique, hydric soil indicators reveal the unique story of the land beneath our feet."
Beyond wetland delineation, soil classification is a key component of environmental restoration, conservation planning, and land management. The ability to analyze and interpret soil properties helps scientists understand long-term landscape changes, assess soil health, and develop strategies for sustainable land use.
The Munsell Soil Color Chart is particularly valuable in tracking environmental shifts. Subtle variations in soil color can indicate changes in moisture levels, organic content, or chemical composition—factors that influence everything from erosion control to habitat restoration. Soil analysis can reveal how a site has responded to past land use or whether a conservation area is recovering as expected.
By decoding soil characteristics with precision, environmental professionals can make informed decisions that support healthy ecosystems, improve water management, and guide responsible development. The Munsell Soil Color Chart remains a trusted resource in this process, providing a universal language for soil classification and environmental assessment.
Princeton Hydro President Geoffrey M. Goll, PE, recently traveled to Durban, South Africa, to participate in a symposium focused on “Dam Management and Restoration of River Connectivity.”
Organized by the Ruben Rocha of the Dam Removal South Africa initiative of the former World Fish Migration Foundation (WFMF) and the Institute of Natural Resources (INR), this inaugural event brought together international experts, local researchers, and representatives from government agencies and environmental organizations to explore the complex challenges of balancing water security with ecosystem protection in South Africa. The dynamic two-day program featured on-site exploration, expert-led presentations, and collaborative “World Cafe” workshops aimed at advancing sustainable water management practices across South Africa.
The workshop kicked off with a visit to two weirs on the lower uMkhomazi River: the Goodenough Weir and the Department of Water and Sanitation Weir. Participants gained a firsthand perspective on the intricate and difficult balance between infrastructure development and ecosystem function preservation. At the Goodenough Weir, construction efforts to upgrade the structure were underway, incorporating a fish passage designed to support the upstream migration of native fish species. In contrast, just upstream, the outdated Department of Water and Sanitation Weir presented a stark example of the challenges posed by aging infrastructure. Its obsolete design continues to block river connectivity and disrupt natural habitats, impeding the broader success of restoration efforts downstream. The success of the Goodenough Weir’s fish passage structure will be evaluated for its effectiveness once in operation.
This field visit provided an immersive learning experience, sparking meaningful discussions among attendees. Participants explored strategies for harmonizing ecological priorities with critical infrastructure needs, emphasizing the importance of collaboration and adopting a holistic, big-picture approach to sustainable water management and river connectivity.
The second day of the workshop was packed with impactful presentations and interactive discussions, offering both local and international perspectives on sustainable water management and river restoration.
South African representatives shared innovative strategies and real-world examples from their work:
Navashni Govender of SANParks highlighted South Africa's groundbreaking efforts in Kruger National Park, where dam removals—the first of their kind on the African continent—have restored natural river flow and enhanced biodiversity.
Nkosinjani Mkhize of the Pongola-Umzimkhulu Catchment Management Agency discussed strategies for balancing social and ecological demands.
Futhi Vilakazi of uMngeni-uThukela Water addressed the dual challenge of securing water supplies and protecting ecosystems, with a focus on catchment interventions.
Dr. Andrew Blackmore of KZN Wildlife provided a detailed exploration of South Africa’s complex regulatory framework for dam removal, shedding light on how to navigate environmental legislation effectively.
The program also welcomed two international experts who enriched the conversation with perspectives from their respective regions:
Princeton Hydro President Geoffrey M. Goll, PE delivered a presentation titled “Sediment Management Before, During, and After Dam/Weir Removal,” emphasizing the critical role of sediment in maintaining river health. Through case studies and strategies from the United States, he demonstrated how proactive sediment management can enhance both the ecological and social benefits of barrier removal. His insights underscored the interconnected challenges of sedimentation, water quality, and dam removal—issues South Africa must address to achieve sustainable water resource management.
Mr. Hamish Moir of Scotland’s CBEC Eco-Engineering shared success stories from Europe, including projects in Scotland, the UK, and Iceland. His presentation on reconnecting rivers through selective barrier removal showcased how nature-based solutions can improve ecosystem dynamics and mitigate flood risks, offering valuable lessons for South Africa.
The day concluded with interactive "World Café" workshop sessions focused on key themes such as stakeholder involvement, governance mechanisms, water scarcity, biodiversity, socio-economic impacts, and funding models. Participants explored solutions for integrating ecological, social, and economic priorities into river restoration projects.
Together, the presentations and workshops provided actionable knowledge and innovative approaches to advancing river connectivity and sustainable dam management.
After the conference, Geoff had the honor of being invited by Dr. Matthew Burnett to tour the University of KwaZulu-Natal’s hydraulics lab. Dr. Burnett, who serves as Principal Scientist at the Institute of Natural Resources, Honorary Freshwater Ecology Researcher at the University of KwaZulu-Natal, and coordinator of the “Dam Management and Restoration of River Connectivity” symposium, introduced Geoff to the research being conducted at the University. Researchers there are developing sediment transport models and fish passage testing methods. The emerging program reflects South Africa’s growing commitment to tackling water scarcity, sedimentation, and ecosystem health.
Geoff noted that South Africa is at a pivotal stage in balancing water security with ecological protection. Many dams, while designed for long-term water availability, struggle with sedimentation that reduces reservoir capacity and leads to water quality issues like harmful algal blooms, in addition to creating barriers for diadromous and potamodromous fish, prawn, and crab species. These challenges highlight the need for integrated solutions that address human, agricultural, and biodiversity needs, ensuring sustainable outcomes.
“It was an honor to be invited to South Africa to participate in this important workshop and collaborate with so many talented individuals, all while gaining a deeper understanding of the country’s water resource challenges,” said Geoff. “By exchanging knowledge and ideas from around the world, we can foster innovative approaches and shape balanced solutions.”
Geoff’s participation exemplifies Princeton Hydro’s commitment to advancing global river restoration efforts. By sharing expertise and fostering collaborative dialogue, the workshop in Durban marked a meaningful step toward reconnecting South Africa’s rivers and creating a more sustainable future for its communities and ecosystems.
Before the workshop, Geoff and his wife, Amy, began the trip in Cape Town immersing themselves in South Africa’s rich culture and natural beauty. They explored the city, took part in a guided history tour, and visited the Cape of Good Hope where they admired the stunning coastal landscape, vibrant flora, and fascinating wildlife—including African penguins!
