Rivers that swell during rainy seasons can separate families from schools, healthcare, and markets, making daily routines unpredictable and sometimes unsafe. In the three years before the Imphumelelo Footbridge was completed, five people tragically lost their lives and ten were injured attempting to cross during floods. To help address this challenge, volunteers from the Engineers in Action chapter at Rutgers University joined with other students from the University of Iowa, Hofstra University, and Northwestern University, during the summer of 2025, living and working alongside local communities to build the Imphumelelo Footbridge. Each student chapter is responsible for raising the funds needed to purchase construction materials, making the project both a test of resourcefulness and commitment. For Rutgers students, the experience offered not only the chance to apply technical skills in the field, but also invaluable hands-on learning that deepened their understanding of engineering in practice. At 108 meters long, the Imphumelelo Footbridge is the second longest bridge completed by the Rutgers Chapter in Eswatini, a small, landlocked country in Southern Africa, funded in part by the Microprojects Programme and constructed through the nonprofit Engineers in Action. Now providing safe, year‑round access for more than 1,320 people, the bridge drastically reduces travel distances to healthcare and schools, while standing as a testament to Rutgers students’ commitment to connecting communities and expanding opportunity. This video offers a glimpse into the construction process itself, showing how the Rutgers Engineers in Action Chapter worked alongside community members in Eswatini to bring the bridge to life. Viewers can see the challenges that arose, the teamwork that solved them, and the collaborative spirit that carried the project from planning to completion: Strength in Collaboration: Building the Imphumelelo Footbridge The Imphumelelo Footbridge was the result of four months of careful preplanning and two months of intensive construction in southern Eswatini. This was the farthest site Engineers in Action has worked on, located nearly three hours by car from the nearest city. The remote setting added complexity to the project, but it also underscored the importance of building a reliable crossing for the communities who would depend on it. Construction was not without its challenges. When hoisting the suspension cables, the team’s winch broke because it was old and rusted. With the guidance of local masons, students improvised solutions, even resorting to manually knocking the cables to adjust their height. On anchor pouring day, when several batches of concrete were poured to secure the massive blocks through which the cables run, shifting wood supports forced the team to pause, reassess, and slightly reduce the bearing load to ensure stability. Concrete mixing also presented difficulties, since batches sometimes contained too much water. Rutgers Engineers in Action Co-President, Ula Sokolowski devised a practical solution: mixing gravel, sand, and cement without water, then combining it with the wetter batch to achieve the correct ratio. Reflecting on the experience, Ula noted, "Much of engineering happens behind a desk, but being on site and contributing directly to the build was a completely different experience. Learning how to do every part of the process was not only valuable, but genuinely fun." Aito Sterle, who served as a Quality Control Manager on Rutgers project in the previous year, the project was equally transformative. Aito explained, “The experience completely changed my engineering mindset. Traveling gave me a new perspective on life and exposed me to a whole variety of problems that required creative solutions. As a quality control manager, I was able to dive into the nitty‑gritty of bridge building and really understand the ins and outs of the process. Even though we weren’t part of the initial design, we felt connected to it on site — documenting each step, taking precise measurements, and ensuring everything was engineered to a T. It opened my eyes to how engineering truly works in the real world.” [gallery columns="2" link="none" ids="18956,18959"] The process was a full collaborative effort between students and community members: mixing concrete, sifting sand, moving rocks, and passing buckets of concrete down long human chains. Local masons built walls from stone, while students documented each step and checked measurements to ensure precision. For many community members, the project offered not only a chance to contribute to lasting infrastructure, but also meaningful daily work in a region where jobs are scarce. The bridge’s completion was celebrated not only by the Rutgers team and local residents, but also by community leaders. At the handover ceremony, MP David Ngcamphalala of Qomintaba emphasized the power of collaboration, stating, “Nothing is impossible when people work together.” Engineers in Action Program Manager Ana Jovanovic echoed this sentiment, describing the Imphumelelo Footbridge as “a promise of safety, opportunity, and connection. It will save lives, open access to healthcare, and help the next generation reach their classrooms without fear.” Local leaders also looked ahead to future development. Bucopho of Sigwe expressed gratitude to the Microprojects Programme and appealed for continued support, noting that the dedication of Members of Parliament, Indvuna Yenkhundla, and community leaders gave him confidence that more projects would follow in Qomintaba and Matsanjeni South. These reflections, reported in the Africa-Press – Eswatini, highlight how the Imphumelelo Footbridge was not only a technical achievement but also a symbol of partnership, resilience, and hope for the communities it serves. [gallery columns="2" link="none" ids="18964,18961,18960,18962"] Life with the Community Beyond construction, the Rutgers Engineers in Action team immersed themselves in local life. Prior to travel, students studied language and cultural traditions with the help of a Cultural Relationships Manager, preparing them to build genuine connections. Once in Eswatini, those connections flourished. Community members welcomed the students warmly, eager to share experiences and perspectives. Every Saturday, soccer matches and games brought students and residents together. Music often filled the downtime at the construction site, with dance becoming a universal language that bridged cultural and linguistic gaps. Families opened their homes to the volunteers, with one household affectionately adopting the students for the duration of their stay. For Rutgers students, these relationships were as impactful as the bridge itself. The project was not only about engineering a structure, but also about building trust, friendship, and mutual respect across cultures. How You Can Help Support Engineers in Action Chapter at Rutgers Engineers in Action began in 2009 as an international nonprofit dedicated to connecting isolated communities to essential resources through sustainable infrastructure projects. Originally linked with the Bridges to Prosperity program, Engineers in Action has expanded its mission to include not only footbridges, but also water and sanitation systems that empower underserved communities. Student chapters across the United States and Canada have played a vital role in advancing this mission, gaining hands-on engineering experience while helping communities overcome barriers to education, healthcare, and economic opportunity. To continue building bridges and expanding access to vital resources, Engineers in Action relies on donations. Contributions directly fund materials, logistics, and training that make future projects possible. Supporting Engineers in Action means helping students like those from Rutgers bring their skills to communities in need, while ensuring that families around the world can safely reach schools, hospitals, and markets.

On Saturday, American Littoral Society, in partnership with Princeton Hydro, Borough of Point Pleasant, New Jersey Nature Conservancy, New Jersey Corporate Wetlands Restoration Partnership, and the Point Pleasant Rotary Club, organized dozens of volunteers to restore the shoreline and prevent further erosion at the Slade Dale Sanctuary using recycled Christmas trees. As one of only a few areas of open space left in Point Pleasant, the 13-acre Slade Dale Sanctuary is an important part of the local ecosystem and is home to a number of unique animals and plants. This waterfront preserve along the North Branch Beaver Dam Creek is predominantly tidal marsh, which provides habitat for various birds, including osprey, as well as passive recreation opportunities for the community. Unfortunately, the Slade Dale Sanctuary is disappearing. Since 1930, the shoreline of Slade Dale Sanctuary has retreated approximately 300 feet, equal to the length of a football field, and the channels into the marsh have increased in number and size, according to a study we conducted on behalf of American Littoral Society, for which we provide engineering and natural resources management consulting services. In order to stabilize the shoreline, restore the marsh, and enhance the ecological function and integrity of the preserve, Princeton Hydro developed a conceptual and engineering design using living shoreline features to enhance ecological value and reduce erosion. The final conceptual plan for restoration uses tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion along the coast. To implement this vision and begin building back marsh, the project team is constructing several Christmas tree breakwaters and Christmas tree vanes that mimic naturally occurring debris structures in tidal systems and enhance habitat opportunity and shelter for aquatic life. Volunteers came together on Saturday, May 11 to help with the construction. The Mayor of Point Pleasant Robert A. Sabosik also attended the event, "The Barnegat Bay is an attribute that we all enjoy, and it's something we have to protect." After the 2018 holiday season, the Good Sheppard Lutheran Church in Point Pleasant provided space to collect and store donated Christmas trees, which were then moved to the marsh a few days before the event. On the day of the event, recycled Christmas trees were transported from their staged locations on the marsh to the breakwater sections that were previously installed in the water. To transport them across the water to the pilings, volunteers used two methods: by walking a skiff boat loaded with trees through the water to the pilings or by forming assembly line from the shore to pilings to guide floating trees through the water (check out the album below!). Then, they stuffed the Christmas trees between the pilings, securely tied them down, and staked Christmas trees directly into the creek bottom. For extra assurance, the placed and tied heavy bags of used oyster shells on top of the tree line. Oyster shells were donated by local Monmouth County restaurants in an effort to reduce waste streams. "We really enjoyed participating in this event with American Littoral Society and so many wonderful volunteers,” Christiana L. Pollack, GISP, CFM, Princeton Hydro's Project Manager for this restoration effort. “It is so wonderful to see this project coming to fruition. We’re so proud of our partnership with American Littoral Society and our combined efforts to revitalize and rehabilitate our precious coastal habitats.” Members of the media were invited to attend the volunteer event. News 12 New Jersey covered the event and aired a story on it during their Sunday news broadcast, and NJTV News will be airing the story in the near future. Many thanks to everyone who came out in support of this important restoration effort at Slade Dale Sanctuary American Littoral Society hosts volunteer events throughout the year.

According to American Rivers, “more than 90,000 dams in the country are no longer serving the purpose that they were built to provide decades or centuries ago.” Dam removal has increasingly become the best option for property owners who can no longer afford the rising cost of maintenance and repair work required to maintain these complex structures. Dams can also cause environmental issues such as blocking the movement of fish and other aquatic species, inundating river habitat, impairing water quality, and altering the flow necessary to sustain river life. Removing nonfunctional, outdated dams can bring a river back to its natural state and significantly increase biodiversity for the surrounding watershed. [caption id="attachment_2620" align="alignleft" width="268"] A view from the site of the Heminway Pond Dam removal on July 19, 2018.[/caption] Currently, work is underway in Watertown, Connecticut to remove the Heminway Pond Dam, which restricts fish passage in Steele Brook, creates a pond with increased water temperatures and high bacterial levels due to high geese populations, and encourages deposition of iron precipitate in the stream channel just downstream of the dam. Princeton Hydro designed the engineering plans, managed permitting and is now overseeing construction for the removal project. The removal of the Heminway Pond Dam is identified as an integral component in addressing water quality impairment between the dam and Echo Lake Road. CT DEEP recently published this piece encapsulating the Heminway Pond Dam removal project: REMOVAL OF HEMINWAY POND DAM ON STEELE BROOK IN WATERTOWN UNDERWAY After almost 15 years of discussion and planning with the Town of Watertown and other partners, removal of Heminway Pond Dam on Steele Brook in Watertown finally got underway in early July. Though no longer functional, the dam and pond were originally constructed to supply water for a former thread/string mill. The Town acquired the dam and pond from the Siemon Company, the most recent owner, in 2007 with an eye towards removing the dam, restoring the river and converting the dewatered impoundment area into a passive recreation area, including an extension of the Steele Brook Greenway. With these goals in mind, the Town approached CT DEEP for help with removal of the dam. As it turns out, CT DEEP, has also had a strong interest in seeing this dam removed. It is anticipated that dam removal will improve the hydrology in this section of Steele Brook and eliminate a water quality impairment which manifests itself during hot weather and low flow conditions, as an orange-colored plume of water (due to iron precipitate) immediately downstream of the dam that impacts aquatic life. Dam removal would also benefit fisheries by restoring stream connectivity and habitat. Working towards these mutual goals, CT DEEP was able to provide federal CWA 319 nonpoint source grant funding to USDA NRCS to develop a watershed-based plan for Steele Brook to address nonpoint source impairments that includes a dam removal feasibility analysis for Heminway Pond Dam. Based on the recommendations in this plan, CT DEEP subsequently provided additional 319 grant funds to the Town of Watertown to hire a consultant to develop a dam removal design package, and assist with permitting and preparation. With the Town of Watertown as a strong and vested partner, CT DEEP is now helping this project over the finish line by providing a combination of 319 and SEP funds to accomplish the actual dam removal and restoration of Steele Brook. Dayton Construction Company is performing the construction and Princeton Hydro is the consultant overseeing the project on behalf of the Town. The Northwest Conservation District is also assisting with the project. It is anticipated that the majority of the work will be completed by this Fall. U.S. EPA, ACOE and CT DEEP have all played active roles with regard to permitting the project. Princeton Hydro has designed, permitted, and overseen the reconstruction, repair, and removal of dozens of small and large dams in the Northeast.

The study, which included 12,000 adults, children between 8 and 12, and parents, reveals an alarming disconnection to nature, but also uncovers widespread opportunities for reconnecting and provides actionable recommendations to open the outdoors for all. One key finding of the study was that many people reported having meaningful social experiences in nature, but that many people feel "authentic” nature is too far away, expensive, and inaccessible. However, connecting with nature, along with family or friends, can be as simple as going on a walk in the neighborhood or planting flowers together. As David emphasized in his presentation, if used effectively, the findings from this study can push everyone towards a better relationship with nature, which will in turn create a better tomorrow for future generations. Scroll down to learn more about David. Princeton Hydro, a proud sponsor of the rally, gave two presentations during the conference: “Recognizing The Power of Dam Removal To Reconnect & Restore Our Ecosystem” and “Nonprofit Social Media Hacks.” “Recognizing The Power of Dam Removal To Reconnect & Restore Our Ecosystem" This presentation, which was given by The Nature Conservancy’s River Restoration Manager Beth Styler Barry and Princeton Hydro’s Director of Engineering Services Mary Paist-Goldman, P.E., posed a critical and complicated question to workshop participants: As the dams in our country age, should we continue to repair and maintain the dams or should we remove them? The decision for dam owners and communities often comes down to several factors: current use, cost, and the potential environmental impacts and/or ecological benefits of removal. Dam removal can help restore the river and reconnect the floodplain, yet it’s often a complicated process. Beth and Mary, who are experts in dam removal and restoration, shared with workshop participants the most effective ways to approach a comprehensive, all-inclusive dam removal in New Jersey, with particular emphasis on the Musconetcong Watershed. The presentation reflected the presenters' deep understanding of how to best restore complexity and dynamic function to river systems while incorporating the community’s concerns. Scroll down learn more about the presenters. “Nonprofit Social Media Hacks” Designed for social media beginners and experts alike, this presentation, by NJ Land Rally Planning Committee member Lindsay McNamara and Princeton Hydro’s Communication Strategist Dana Patterson, covered cross-channel techniques to help organizations increase engagement, event attendance, and social buzz. The 30 participants attending the workshop received recommendations on thorough, but free social media management tools, and learned how to efficiently measure social media analytics on a regular basis, utilize apps for creating polished graphics and content for social media, develop strategies for curating content from supporters and volunteers, and the no-hassle way to add Instagram takeovers to a communications calendar.

Rivers that swell during rainy seasons can separate families from schools, healthcare, and markets, making daily routines unpredictable and sometimes unsafe. In the three years before the Imphumelelo Footbridge was completed, five people tragically lost their lives and ten were injured attempting to cross during floods. To help address this challenge, volunteers from the Engineers in Action chapter at Rutgers University joined with other students from the University of Iowa, Hofstra University, and Northwestern University, during the summer of 2025, living and working alongside local communities to build the Imphumelelo Footbridge. Each student chapter is responsible for raising the funds needed to purchase construction materials, making the project both a test of resourcefulness and commitment. For Rutgers students, the experience offered not only the chance to apply technical skills in the field, but also invaluable hands-on learning that deepened their understanding of engineering in practice. At 108 meters long, the Imphumelelo Footbridge is the second longest bridge completed by the Rutgers Chapter in Eswatini, a small, landlocked country in Southern Africa, funded in part by the Microprojects Programme and constructed through the nonprofit Engineers in Action. Now providing safe, year‑round access for more than 1,320 people, the bridge drastically reduces travel distances to healthcare and schools, while standing as a testament to Rutgers students’ commitment to connecting communities and expanding opportunity. This video offers a glimpse into the construction process itself, showing how the Rutgers Engineers in Action Chapter worked alongside community members in Eswatini to bring the bridge to life. Viewers can see the challenges that arose, the teamwork that solved them, and the collaborative spirit that carried the project from planning to completion: Strength in Collaboration: Building the Imphumelelo Footbridge The Imphumelelo Footbridge was the result of four months of careful preplanning and two months of intensive construction in southern Eswatini. This was the farthest site Engineers in Action has worked on, located nearly three hours by car from the nearest city. The remote setting added complexity to the project, but it also underscored the importance of building a reliable crossing for the communities who would depend on it. Construction was not without its challenges. When hoisting the suspension cables, the team’s winch broke because it was old and rusted. With the guidance of local masons, students improvised solutions, even resorting to manually knocking the cables to adjust their height. On anchor pouring day, when several batches of concrete were poured to secure the massive blocks through which the cables run, shifting wood supports forced the team to pause, reassess, and slightly reduce the bearing load to ensure stability. Concrete mixing also presented difficulties, since batches sometimes contained too much water. Rutgers Engineers in Action Co-President, Ula Sokolowski devised a practical solution: mixing gravel, sand, and cement without water, then combining it with the wetter batch to achieve the correct ratio. Reflecting on the experience, Ula noted, "Much of engineering happens behind a desk, but being on site and contributing directly to the build was a completely different experience. Learning how to do every part of the process was not only valuable, but genuinely fun." Aito Sterle, who served as a Quality Control Manager on Rutgers project in the previous year, the project was equally transformative. Aito explained, “The experience completely changed my engineering mindset. Traveling gave me a new perspective on life and exposed me to a whole variety of problems that required creative solutions. As a quality control manager, I was able to dive into the nitty‑gritty of bridge building and really understand the ins and outs of the process. Even though we weren’t part of the initial design, we felt connected to it on site — documenting each step, taking precise measurements, and ensuring everything was engineered to a T. It opened my eyes to how engineering truly works in the real world.” [gallery columns="2" link="none" ids="18956,18959"] The process was a full collaborative effort between students and community members: mixing concrete, sifting sand, moving rocks, and passing buckets of concrete down long human chains. Local masons built walls from stone, while students documented each step and checked measurements to ensure precision. For many community members, the project offered not only a chance to contribute to lasting infrastructure, but also meaningful daily work in a region where jobs are scarce. The bridge’s completion was celebrated not only by the Rutgers team and local residents, but also by community leaders. At the handover ceremony, MP David Ngcamphalala of Qomintaba emphasized the power of collaboration, stating, “Nothing is impossible when people work together.” Engineers in Action Program Manager Ana Jovanovic echoed this sentiment, describing the Imphumelelo Footbridge as “a promise of safety, opportunity, and connection. It will save lives, open access to healthcare, and help the next generation reach their classrooms without fear.” Local leaders also looked ahead to future development. Bucopho of Sigwe expressed gratitude to the Microprojects Programme and appealed for continued support, noting that the dedication of Members of Parliament, Indvuna Yenkhundla, and community leaders gave him confidence that more projects would follow in Qomintaba and Matsanjeni South. These reflections, reported in the Africa-Press – Eswatini, highlight how the Imphumelelo Footbridge was not only a technical achievement but also a symbol of partnership, resilience, and hope for the communities it serves. [gallery columns="2" link="none" ids="18964,18961,18960,18962"] Life with the Community Beyond construction, the Rutgers Engineers in Action team immersed themselves in local life. Prior to travel, students studied language and cultural traditions with the help of a Cultural Relationships Manager, preparing them to build genuine connections. Once in Eswatini, those connections flourished. Community members welcomed the students warmly, eager to share experiences and perspectives. Every Saturday, soccer matches and games brought students and residents together. Music often filled the downtime at the construction site, with dance becoming a universal language that bridged cultural and linguistic gaps. Families opened their homes to the volunteers, with one household affectionately adopting the students for the duration of their stay. For Rutgers students, these relationships were as impactful as the bridge itself. The project was not only about engineering a structure, but also about building trust, friendship, and mutual respect across cultures. How You Can Help Support Engineers in Action Chapter at Rutgers Engineers in Action began in 2009 as an international nonprofit dedicated to connecting isolated communities to essential resources through sustainable infrastructure projects. Originally linked with the Bridges to Prosperity program, Engineers in Action has expanded its mission to include not only footbridges, but also water and sanitation systems that empower underserved communities. Student chapters across the United States and Canada have played a vital role in advancing this mission, gaining hands-on engineering experience while helping communities overcome barriers to education, healthcare, and economic opportunity. To continue building bridges and expanding access to vital resources, Engineers in Action relies on donations. Contributions directly fund materials, logistics, and training that make future projects possible. Supporting Engineers in Action means helping students like those from Rutgers bring their skills to communities in need, while ensuring that families around the world can safely reach schools, hospitals, and markets.

To prevent further erosion at the Slade Dale Sanctuary in Point Pleasant, dozens of volunteers helped stabilize the shoreline using a technique that has never been done before in New Jersey. On Saturday, American Littoral Society, in partnership with Princeton Hydro, Borough of Point Pleasant, New Jersey Nature Conservancy, New Jersey Corporate Wetlands Restoration Partnership, and the Point Pleasant Rotary Club, organized dozens of volunteers to restore the shoreline and prevent further erosion at the Slade Dale Sanctuary using recycled Christmas trees.
As one of only a few areas of open space left in Point Pleasant, the 13-acre Slade Dale Sanctuary is an important part of the local ecosystem and is home to a number of unique animals and plants. This waterfront preserve along the North Branch Beaver Dam Creek is predominantly tidal marsh, which provides habitat for various birds, including osprey, as well as passive recreation opportunities for the community.
Unfortunately, the Slade Dale Sanctuary is disappearing. Since 1930, the shoreline of Slade Dale Sanctuary has retreated approximately 300 feet, equal to the length of a football field, and the channels into the marsh have increased in number and size, according to a study we conducted on behalf of American Littoral Society, for which we provide engineering and natural resources management consulting services.
In order to stabilize the shoreline, restore the marsh, and enhance the ecological function and integrity of the preserve, Princeton Hydro developed a conceptual and engineering design using living shoreline features to enhance ecological value and reduce erosion. The final conceptual plan for restoration uses tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion along the coast.
To implement this vision and begin building back marsh, the project team is constructing several Christmas tree breakwaters and Christmas tree vanes that mimic naturally occurring debris structures in tidal systems and enhance habitat opportunity and shelter for aquatic life. Volunteers came together on Saturday, May 11 to help with the construction. The Mayor of Point Pleasant Robert A. Sabosik also attended the event, "The Barnegat Bay is an attribute that we all enjoy, and it's something we have to protect."
After the 2018 holiday season, the Good Sheppard Lutheran Church in Point Pleasant provided space to collect and store donated Christmas trees, which were then moved to the marsh a few days before the event. On the day of the event, recycled Christmas trees were transported from their staged locations on the marsh to the breakwater sections that were previously installed in the water. To transport them across the water to the pilings, volunteers used two methods: by walking a skiff boat loaded with trees through the water to the pilings or by forming assembly line from the shore to pilings to guide floating trees through the water (check out the album below!). Then, they stuffed the Christmas trees between the pilings, securely tied them down, and staked Christmas trees directly into the creek bottom. For extra assurance, the placed and tied heavy bags of used oyster shells on top of the tree line. Oyster shells were donated by local Monmouth County restaurants in an effort to reduce waste streams.
"We really enjoyed participating in this event with American Littoral Society and so many wonderful volunteers,” Christiana L. Pollack, GISP, CFM, Princeton Hydro's Project Manager for this restoration effort. “It is so wonderful to see this project coming to fruition. We’re so proud of our partnership with American Littoral Society and our combined efforts to revitalize and rehabilitate our precious coastal habitats.”
Many thanks to everyone who came out in support of this important restoration effort at Slade Dale Sanctuary American Littoral Society hosts volunteer events throughout the year. Go here to get involved.
As dams age and decay, they can become public safety hazards, presenting a failure risk and flooding danger. According to American Rivers, “more than 90,000 dams in the country are no longer serving the purpose that they were built to provide decades or centuries ago.” Dam removal has increasingly become the best option for property owners who can no longer afford the rising cost of maintenance and repair work required to maintain these complex structures.
Dams can also cause environmental issues such as blocking the movement of fish and other aquatic species, inundating river habitat, impairing water quality, and altering the flow necessary to sustain river life. Removing nonfunctional, outdated dams can bring a river back to its natural state and significantly increase biodiversity for the surrounding watershed.
Currently, work is underway in Watertown, Connecticut to remove the Heminway Pond Dam, which restricts fish passage in Steele Brook, creates a pond with increased water temperatures and high bacterial levels due to high geese populations, and encourages deposition of iron precipitate in the stream channel just downstream of the dam.
Princeton Hydro designed the engineering plans, managed permitting and is now overseeing construction for the removal project. The removal of the Heminway Pond Dam is identified as an integral component in addressing water quality impairment between the dam and Echo Lake Road.
REMOVAL OF HEMINWAY POND DAM ON STEELE BROOK IN WATERTOWN UNDERWAY After almost 15 years of discussion and planning with the Town of Watertown and other partners, removal of Heminway Pond Dam on Steele Brook in Watertown finally got underway in early July. Though no longer functional, the dam and pond were originally constructed to supply water for a former thread/string mill. The Town acquired the dam and pond from the Siemon Company, the most recent owner, in 2007 with an eye towards removing the dam, restoring the river and converting the dewatered impoundment area into a passive recreation area, including an extension of the Steele Brook Greenway. With these goals in mind, the Town approached CT DEEP for help with removal of the dam. As it turns out, CT DEEP, has also had a strong interest in seeing this dam removed. It is anticipated that dam removal will improve the hydrology in this section of Steele Brook and eliminate a water quality impairment which manifests itself during hot weather and low flow conditions, as an orange-colored plume of water (due to iron precipitate) immediately downstream of the dam that impacts aquatic life. Dam removal would also benefit fisheries by restoring stream connectivity and habitat. Working towards these mutual goals, CT DEEP was able to provide federal CWA 319 nonpoint source grant funding to USDA NRCS to develop a watershed-based plan for Steele Brook to address nonpoint source impairments that includes a dam removal feasibility analysis for Heminway Pond Dam. Based on the recommendations in this plan, CT DEEP subsequently provided additional 319 grant funds to the Town of Watertown to hire a consultant to develop a dam removal design package, and assist with permitting and preparation. With the Town of Watertown as a strong and vested partner, CT DEEP is now helping this project over the finish line by providing a combination of 319 and SEP funds to accomplish the actual dam removal and restoration of Steele Brook. Dayton Construction Company is performing the construction and Princeton Hydro is the consultant overseeing the project on behalf of the Town. The Northwest Conservation District is also assisting with the project. It is anticipated that the majority of the work will be completed by this Fall. U.S. EPA, ACOE and CT DEEP have all played active roles with regard to permitting the project.

“It was fascinating to discuss a topic, such as the removal of dams, right as Brazil is focusing on building more hydro capacity,” said Laura. “Hopefully it is a sign that the hydro industry in Brazil, along with all the great Brazilian fisheries researchers, are quite forward thinking and are determined to maintain their country's rich species diversity while also enhancing their energy options.”
The workshop, hosted by CEMIG and held at UFMG, involved many universities, including our workshop host Paulo Pompeu from UFLA, Dr. Paul Kemp from University of Southhampton, Dr. Jesse O'Hanley of Kent Business School, and many others.
The gathering inspired a lot of interesting dialogue around dam removal, optimizing locations for new hydro facilities, and how to best sustain connectivity and species diversity. Laura’s presentation entitled "Dam removal in the United States" along with the other conference presentations will be available on the CEMIG website soon or check back here on the Princeton Hydro blog for presentation links.
