For the first time in over 200 years, the lower Bushkill Creek is now free-flowing and fully reconnected with the Delaware River and, ultimately, the Atlantic Ocean. This tremendous achievement signals a turning point for the ecological health of the Bushkill Creek watershed, supporting the passage of migratory fish species, bolstering ecologically beneficial freshwater mussel populations, reconnecting river habitats that benefit fish and wildlife, and enhancing water quality across the Delaware River Basin, which provides drinking water to millions of people.
"This significant, yearslong restoration effort exemplifies the power of conservation partnerships to achieve profound ecological impact,” said Princeton Hydro President and Founding Principal Geoffrey M. Goll, PE “The restored Bushkill Creek is more than a reconnected waterway—it is a revitalized natural resource that enhances biodiversity, supports community recreation, and contributes to the local economy in sustainable ways.”




Restoring Bushkill Creek’s Natural Flow
Bushkill Creek begins at the foot of Blue Mountain in Bushkill Township, Pennsylvania, and flows for 22 miles through agricultural and suburban areas, including Easton. The limestone stream supports a thriving wild brown trout population and is designated as a “high-quality, cold-water fishery” cherished by anglers and the local community.
Since 2021, Wildlands Conservancy has led the charge to remove five aging dams along Bushkill Creek. While these structures once served industrial and community functions, they had become barriers to fish migration, disrupted the creek’s natural flow, and contributed to localized flooding and water quality issues. Now, with these obstacles cleared, Bushkill Creek flows freely from its headwaters to its confluence with the Delaware River.
The map below, created by the Wildlands Conservancy, shows the locations of four dam removals on Bushkill Creek:
Along the creek, the removal of Dam #2 signifies a momentous occasion in its restoration journey, representing the most recent advancement in dam removal efforts.

The Power of Partnerships in Restoring Bushkill Creek
Led by the Wildlands Conservancy, the restoration of Bushkill Creek involved more than 20 stakeholders, including the Delaware River Basin Commission, Lafayette College, Pennsylvania Department of Environmental Protection, National Fish and Wildlife Foundation, Pennsylvania Department of Conservation and Natural Resources, and Princeton Hydro.
In a press release from the Wildlands Conservancy, President Christopher Kocher, praised the collaborative effort, stating, “This yearslong effort is a win for clean water for all the communities living in connection with the Bushkill Creek. It’s a wonderful example of the power of partnerships, and what community can do for community when nonprofits, local government, and state and federal agencies pool ideas and resources to invest in our treasured natural areas.”
To celebrate this tremendous accomplishment, Wildlands Conservancy, project partners, funders, and community volunteers gathered on October 15, 2024, at Lafayette College’s Karl Stirner Arts Trail.

The event included a volunteer-powered wildflower planting to complete the restoration work at this site, where Dam #1, formerly owned by Lafayette College, had been removed in 2023 with the support of Princeton Hydro. Spanning 90 feet in length and standing 4 feet high, the dam had severely obstructed fish passage, contributed to local flooding, and impaired water quality over time. The college enthusiastically supported the dam's removal, dedicating substantial resources to see the project to completion.

Princeton Hydro is excited to announce that the Musconetcong Island Park Project received the New Jersey Future 2024 Smart Growth Award. This project, led by the Musconetcong Watershed Association (MWA), transformed a crumbling, long-abandoned laboratory into a vibrant, accessible riparian park space that provides opportunities for fishing, wading, paddling, and viewing wildlife in Bethlehem Township, NJ.

The site, which once housed a two-story concrete block laboratory used by the Asbury Graphite Mill, had become a hazard after decades of disuse. Located on a quarter-acre island in the Musconetcong River, the building was not only structurally unsound but also in the floodway of the River, posing ongoing risks to the surrounding environment. Through a collaborative, multi-year effort, the abandoned building was demolished, the area was restored, and the island was transformed into a welcoming, accessible space for public enjoyment and recreation.
The image below shows the old stairway, laboratory building, and island space with a white outline depicting the project area:

The Musconetcong Island Park Project represents a successful collaboration among numerous partners. Led by MWA, the project involved National Fish and Wildlife Foundation, the Township of Bethlehem, Harrington Construction, and Princeton Hydro.
Princeton Hydro provided engineering and environmental consulting services for the project. Our scientists and engineers completed all necessary permitting, designed both the conceptual and final restoration plans, and oversaw construction throughout the project.

Funding for the project was secured through three primary sources: New Jersey Green Acres Program, National Park Foundation, and U.S. Fish and Wildlife Service’s Delaware Watershed Conservation Fund. These grants were instrumental in facilitating the transformation of an industrial relic into a thriving park space, balancing the preservation of the river's natural resources with the creation of an accessible community destination.

The two-story concrete block building that once stood on Musconetcong Island was originally the Asbury Graphite Mill laboratory, constructed between 1925 and 1940. It was built on the foundation of a woolen factory that had been destroyed by fire in 1881. The laboratory was used for testing graphite, an inert and non-toxic mineral primarily used for lubrication and other industrial applications. Graphite refining began in Asbury in 1895, when Harry M. Riddle purchased the existing mills and converted them for this specialized purpose.
By the early 1980s, the laboratory was abandoned due to frequent flooding and a lack of modern plumbing. Despite its industrial history, the building had become a safety and environmental concern due to its floodway location and deteriorating condition. In 1999, the laboratory building was donated to the Musconetcong Watershed Association, who then initiated efforts to restore the site and transform it into a valuable public resource.
Today, the island has been transformed into a place where residents and visitors can enjoy the Musconetcong River. With improved access, new stairways, and interpretive signage sharing the history of the area, Musconetcong Island Park is a prime example of how thoughtful design can blend environmental restoration with community-focused development.

“We are honored to have contributed to the transformation of Musconetcong Island Park and proud to see this project recognized with a New Jersey Future Smart Growth Award for its role in enhancing the Musconetcong River Watershed. It reflects our commitment to sustainable design and the power of collaboration in creating lasting, positive impacts for both the environment and the community. It’s truly a win-win — removing an obstruction from the floodway while providing public access to the river,” said Geoffrey M. Goll PE, President of Princeton Hydro.
Since 2002, the New Jersey Future Smart Growth Awards have celebrated the best examples of sustainable planning and development across the state. The Musconetcong Island Park Project exemplifies these values by enhancing public access to nature, improving resilience to flooding, and fostering sustainable recreation opportunities in the heart of Bethlehem Township. The project showcases the importance of balancing environmental restoration with community needs, creating a space where people can connect with nature while preserving and protecting it for future generations.
The 2024 New Jersey Future Smart Growth Awards recognize six outstanding projects that exemplify innovative and sustainable development. This year’s award ceremony and celebration took place yesterday at the New Brunswick Performing Arts Center.

In a momentous occasion for environmental conservation, a dam removal on Bushkill Creek is underway, building upon a new era for this cherished limestone stream.
This dam removal marks another important milestone in restoring Bushkill Creek back to its natural, free-flowing state; connecting migratory fish species like alewife and American shad with upstream spawning grounds; and helping to revitalize ecologically-beneficial freshwater mussels colonies and populations of trout and other residential fish species.




Freeing Bushkill Creek One Dam at a Time
Bushkill Creek begins at the foot of Blue Mountain in Bushkill Township, Pennsylvania and flows 22 miles before its confluence with the Delaware River. The limestone stream flows through agricultural and suburban areas, as well as Easton, and supports a large wild brown trout population. It is designated as a “high quality, cold-water fishery” and treasured by anglers and the surrounding community as an important resource in an urban environment.
In 2022, Wildlands Conservancy contracted Princeton Hydro to design, permit, and oversee construction for the removal of four dams along Bushkill Creek. The Crayola Dam, also called Dam #4, was the first of the four dam removal projects to be completed.
The map below shows the location of the next three Bushkill Creek dams being removed:

The demolition and removal of Dam #1 commenced on July 7, 2023 and is scheduled for completion in August. The site labeled as Dam #3 is scheduled for demolition and removal later this year. And, the site labeled as Dam #2, is scheduled for removal in the summer of 2024.
Removing nonfunctional, outdated dams from the Bushkill and allowing the creek to return to a natural, free-flowing state will have myriad ecological benefits.




Removing the Bushkill’s First Barrier
Dam #1, the first barrier on the Bushkill, is located directly upstream from the Creek’s confluence with the Delaware River. Previous to this removal process, Dam #1 was the upstream limit for migratory fish like alewife, striped bass, and shad.
Dam #1 is owned by Lafayette College in Easton, Pennsylvania. It spans an impressive length of 90 feet, width of 14 feet, and stands 4-feet high. Having been constructed in 1793, the dam had fallen into a state of disrepair, with crumbling concrete impacting the integrity of the streambank retaining wall. Consequently, the dam and associated impoundment have had detrimental effects on the creek's ecosystem, obstructing fish passage, exacerbating local flooding, and degrading water quality. Professors and students of the College have tried for years to effectuate Bushkill Creek dam removals to improve the aquatic environment.

By removing the dam, the project team aims to improve water quality, restore the creek back to its natural flowing state, reconnect river habitats that benefit fish and wildlife, and significantly increase biodiversity for the surrounding watershed. The project work also includes stabilizing the streambank, expanding riparian buffers, planting native trees and shrubs to filter runoff, and installing in-stream structures to restore fish habitat, which has numerous and far-reaching ecological benefits. It is important to note that the project's scope involves minimal disturbance, impacting less than one acre of land surrounding the dam.

Collaborative Efforts Yield Success
The continued effort to restore Bushkill Creek with the removal of Barrier #1, which has been 10-years in the making, serves as a testament to the unwavering dedication displayed by a diverse array of 20+ stakeholders, including Delaware River Basin Commission, Lafayette College, Pennsylvania Department of Environmental Protection, National Fish and Wildlife Foundation (NFWF), Pennsylvania Department of Conservation and Natural Resources, and Princeton Hydro.
According to the Wildlands Conservancy, the initial natural resource damage assessment funding came following a fly ash spill from the Martins Creek Power Plant in 2005. The settlement, which was reached in 2016, totaled $1.3 million, with $902,150 going to the Delaware River Basin Commission for dam removal projects and $50,000 going to the Commission to manage mussel restoration. Additional funding for the overall project came from NFWF's Delaware Watershed Conservation Fund ($2,049,200), and Northampton County's Livable Landscapes program ($100,000).



Princeton Hydro has designed, permitted, and overseen the reconstruction, repair, and removal of 80+ small and large dams in the Northeast. For over a decade, Princeton Hydro has partnered with Wildlands Conservancy to remove dams in the Lehigh River Valley.

For the first time in over 200 years, the lower Bushkill Creek is now free-flowing and fully reconnected with the Delaware River and, ultimately, the Atlantic Ocean. This tremendous achievement signals a turning point for the ecological health of the Bushkill Creek watershed, supporting the passage of migratory fish species, bolstering ecologically beneficial freshwater mussel populations, reconnecting river habitats that benefit fish and wildlife, and enhancing water quality across the Delaware River Basin, which provides drinking water to millions of people.
"This significant, yearslong restoration effort exemplifies the power of conservation partnerships to achieve profound ecological impact,” said Princeton Hydro President and Founding Principal Geoffrey M. Goll, PE “The restored Bushkill Creek is more than a reconnected waterway—it is a revitalized natural resource that enhances biodiversity, supports community recreation, and contributes to the local economy in sustainable ways.”




Restoring Bushkill Creek’s Natural Flow
Bushkill Creek begins at the foot of Blue Mountain in Bushkill Township, Pennsylvania, and flows for 22 miles through agricultural and suburban areas, including Easton. The limestone stream supports a thriving wild brown trout population and is designated as a “high-quality, cold-water fishery” cherished by anglers and the local community.
Since 2021, Wildlands Conservancy has led the charge to remove five aging dams along Bushkill Creek. While these structures once served industrial and community functions, they had become barriers to fish migration, disrupted the creek’s natural flow, and contributed to localized flooding and water quality issues. Now, with these obstacles cleared, Bushkill Creek flows freely from its headwaters to its confluence with the Delaware River.
The map below, created by the Wildlands Conservancy, shows the locations of four dam removals on Bushkill Creek:
Along the creek, the removal of Dam #2 signifies a momentous occasion in its restoration journey, representing the most recent advancement in dam removal efforts.

The Power of Partnerships in Restoring Bushkill Creek
Led by the Wildlands Conservancy, the restoration of Bushkill Creek involved more than 20 stakeholders, including the Delaware River Basin Commission, Lafayette College, Pennsylvania Department of Environmental Protection, National Fish and Wildlife Foundation, Pennsylvania Department of Conservation and Natural Resources, and Princeton Hydro.
In a press release from the Wildlands Conservancy, President Christopher Kocher, praised the collaborative effort, stating, “This yearslong effort is a win for clean water for all the communities living in connection with the Bushkill Creek. It’s a wonderful example of the power of partnerships, and what community can do for community when nonprofits, local government, and state and federal agencies pool ideas and resources to invest in our treasured natural areas.”
To celebrate this tremendous accomplishment, Wildlands Conservancy, project partners, funders, and community volunteers gathered on October 15, 2024, at Lafayette College’s Karl Stirner Arts Trail.

The event included a volunteer-powered wildflower planting to complete the restoration work at this site, where Dam #1, formerly owned by Lafayette College, had been removed in 2023 with the support of Princeton Hydro. Spanning 90 feet in length and standing 4 feet high, the dam had severely obstructed fish passage, contributed to local flooding, and impaired water quality over time. The college enthusiastically supported the dam's removal, dedicating substantial resources to see the project to completion.
