[gallery link="none" columns="4" size="medium" ids="17787,17788,7339,17789"] Addressing these impacts requires a thoughtful, site-specific approach. Our team at Princeton Hydro works to design and implement targeted strategies that promote long-term ecological function. These integrated efforts aid in native habitat recovery, enhance water quality, and support compliance with regulatory frameworks. Let’s take a closer look at how invasive species disrupt our ecosystems, why managing them is so important, and the cutting-edge tools and innovative techniques helping to eradicate invasives and restore balance to delicate ecosystems. Understanding the Impacts of Invasive Species Invasive species are organisms introduced outside their native range that proliferate in new environments, often to the detriment of local ecosystems and biodiversity. Although some introductions happen naturally, most are caused by human activity—through commercial shipping and transport, travel and outdoor recreation, or sometimes deliberate introduction. Once established, invasive species often outcompete native species by growing more aggressively, reproducing more rapidly, and exploiting resources more efficiently. These advantages are amplified by the absence of natural predators and environmental controls that would normally regulate their populations. This can lead to a cascade of ecological consequences:

Once established, invasive species often outcompete native species by growing more aggressively, reproducing more rapidly, and exploiting resources more efficiently. These advantages are amplified by the absence of natural predators and environmental controls that would normally regulate their populations.
This can lead to a cascade of ecological consequences:
Take common reed (Phragmites australis), for example. This fast-growing plant has overtaken many wetlands, meadows, and shorelines, forming dense stands that outcompete native vegetation. These monocultures reduce food sources that native species rely on and block the movement of wildlife between critical habitats. According to the National Invasive Species Information Center (NISIC), Phragmites was most likely introduced during the 1800s in ballast material used on ships. It was initially established along the Atlantic coast and quickly spread across the continent.
Another example of an aggressive invasive species is Eurasian watermilfoil (Myriophyllum spicatum), a submerged perennial aquatic plant that grows in lakes and ponds. Native to Europe, Asia, and North Africa, it was discovered in the eastern U.S. in the early 1900s, likely introduced and spread through the movement of watercraft. It establishes itself very quickly, grows rapidly, and spreads easily, forming dense mats at the water’s surface.
Left unmanaged, aggressive invasives like Phragmites and Eurasian watermilfoil can severely impact the stability of critical environmental systems. Effective control strategies help restore balance, preserve biodiversity, and safeguard the services ecosystems provide to humans and wildlife alike.
At Princeton Hydro, we use a multifaceted approach to invasive species control, employing mechanical, herbicidal, and biological strategies depending on the specific site conditions and project goals. One of our most effective tools is the Marsh Master® 2MX-KC-FH, a fully amphibious machine built to operate with minimal environmental disruption.
Equipped with hydraulic rotary cutting blades, a rear mounted roller/chopper attachment, and a front vegetation plow, the Marsh Master® cuts through dense vegetation like Phragmites, then chops and rolls the stalks, effectively preparing the soil for native seed germination or plug installation, making it ideal for nature preserves, canal banks, and restoration sites. Its light footprint (less than one pound per square inch) means it can traverse sensitive areas without damaging the soil or root layer.
Take a look at the Marsh Master® in the field, tackling Phragmites in tough terrain:
When paired with herbicide treatments and long-term monitoring, this approach has proven very effective in eradicating invasives, restoring wetland biodiversity, improving water quality, and creating wildlife habitat. Each site is carefully analyzed and, when required for optimal non-native plant management, a site-specific USEPA and state-registered herbicide is chosen to control the target plants while preserving the desirable, native vegetation currently populating the site. Application techniques, which are also specific to each site, include machine broadcast spraying, backpack foliar spraying, hand-wiping, basal applications, herbicide injection lances, along with various other techniques.
In partnership with GreenVest and the U.S. Army Corps of Engineers Baltimore District, Princeton Hydro contributed to a tidal marsh restoration project along the Patapsco River in Baltimore, Maryland. This initiative is part of the broader “Reimagine Middle Branch” plan, a community-driven revitalization effort to restore natural habitat and improve public access along 11 miles of Patapsco River shoreline.
At the project site near Reed Bird Island, roughly five acres of marsh had been overtaken by dense stands of Phragmites. The goal was to restore hydrologic connections to the Patapsco River and convert the monoculture into a thriving mosaic of native marsh vegetation. Our team used the Marsh Master® to mow and manage the Phragmites, followed by mechanical grading and sediment redistribution to create high and low marsh zones. The restoration plan included planting 5+ acres with a combination of native species and incorporating habitat features like woody debris and unplanted cobblestone patches to facilitate fish passage.
This project demonstrates how targeted invasive species control can support large-scale ecosystem restoration, community-led initiatives, and watershed-wide environmental goals.
Princeton Hydro has worked alongside New Jersey’s Mercer County Park Commission for over a decade to restore and protect some of the region’s most ecologically valuable landscapes. From comprehensive planning to boots-on-the-ground restoration, our efforts have focused on mitigating the spread of invasive species and promoting long-term ecological resilience.
John A. Roebling Memorial Park, part of the Abbott Marshlands, an ecologically rich freshwater tidal ecosystem that contains valuable habitat for many rare species, experienced a significant amount of loss and degradation, partially due to the introduction of Phragmites. In areas where Phragmites had overtaken native wetland communities, our team developed and executed an invasive species management plan tailored to the park’s unique hydrology and habitat types. Seasonal mowing in the winter and early spring with the Marsh Master® and targeted herbicide applications helped suppress invasive growth and enabled the rebound of native species, including Wild rice (Zizania aquatica), a culturally and ecologically significant plant.
Building on that success, we contributed to the development and implementation of the Master Plan for the Miry Run Dam Site 21, a comprehensive roadmap for ecological restoration and public access. We are advancing that vision through mitigating invasive species (primarily Phragmites), leading lake dredging, and executing a variety of habitat uplift efforts. Click here to learn more about this award-winning restoration initiative.
In 2024, Mercer County retained Princeton Hydro under an on-call contract for invasive species management across its park system, enabling our team to respond rapidly to emerging threats and support the county’s ongoing commitment to long-term ecosystem health.
At the Lower Raritan Mitigation Site in central New Jersey, Princeton Hydro has led a multi-year invasive species control effort as part of a larger wetland and stream restoration initiative. Dominated by reed canary grass (Phalaris arundinacea) and Phragmites, the site had lost most (if not all) of its native biodiversity and ecological function.
Our team used a phased approach—mechanical mowing, herbicide treatment, and active planting of native species—to gradually suppress invasives and restore a healthy plant community. Monitoring data over several growing seasons has shown a significant decrease in invasive cover and a measurable increase in native diversity. Ongoing eradication of aggressive species and the promotion of native plant diversity are steadily guiding the site toward a resilient, self-sustaining ecosystem.
Owned and managed by The Nature Conservancy in New Jersey, the South Cape May Meadows Preserve is a 200-acre freshwater wetland and coastal habitat in southern New Jersey that serves as a critical refuge for migratory birds and other native wildlife. The preserve attracts over 90,000 visitors each year and is internationally recognized as a prime birdwatching destination.
Princeton Hydro is collaborating with The Nature Conservancy on a multi-faceted effort to both improve public access and restore the site’s ecological integrity. In 2023 and 2024, our team initiated the mechanical removal of dense stands of Phragmites using the Marsh Master® to suppress monocultures and promote native plant regeneration. Future phases may include targeted herbicide treatments and additional mechanical work.
In addition to the invasive species management component, this project collaboration has led to the construction of 2,675 feet of new elevated boardwalks, a 480-square-foot viewing platform, and enhancements to existing trails. Designing and installing these features across sensitive wetland terrain required a thoughtful, low-impact approach. The result is a more welcoming, species-rich, and resilient landscape that invites people into nature while actively protecting it.
Invasive vegetation doesn’t just affect wild landscapes, it also poses challenges for stormwater infrastructure. Many municipalities struggle with invasives overtaking stormwater basins, reducing their capacity and function, which can lead to violations of Municipal Separate Storm Sewer System (MS4) permits and municipality stormwater management regulatory requirements.
Princeton Hydro designs and implements comprehensive stormwater basin maintenance programs that include invasive species management. Removing Phragmites, broadleaf cattail (Typha latifolia), and other aggressive species from stormwater infrastructure helps to restore hydrologic flow and ensures the basins perform as designed. These maintenance programs also help maintain MS4 compliance, protect downstream water quality, and reduce flooding risks—while enhancing habitat value where possible.
The fight against invasive and aggressive non-native species is ongoing, and success requires a combination of science, strategy, and stewardship. Each effort implemented and every acre reclaimed is a step toward protecting the ecosystems we all depend on.
Each year on March 3rd, World Wildlife Day offers an opportunity to celebrate the incredible biodiversity of our planet and raise awareness about the importance of protecting and restoring critical habitats. In that spirit, we’re highlighting a transformative project that turned degraded wetlands into a thriving wildlife sanctuary: The Pin Oak Forest Stream, Wetland, and Upland Enhancement Project in Woodbridge, New Jersey, stands as a testament to the power of restoration and the lasting impact of ecological stewardship.
Located in a highly developed region of Middlesex County, the Pin Oak Forest Conservation Area is a rare ecological gem—a 97-acre open space containing a critical wetland complex at the headwaters of Woodbridge Creek. Before restoration efforts began, the area suffered from habitat fragmentation, wetland degradation, and the encroachment of invasive species, all of which had significantly reduced biodiversity and threatened native wildlife.
Recognizing the urgency of intervention, a diverse coalition of government agencies, NGOs, and private industry, including Middlesex County Office of Parks and Recreation, Woodbridge Township, Woodbridge River Watch, New Jersey Freshwater Wetlands Mitigation Council, GreenTrust Alliance, GreenVest, and Princeton Hydro, came together to design and implement a comprehensive restoration plan aimed at revitalizing the area’s natural functions.
The project converted nearly 29 acres of degraded wetlands, over 1,000 feet of channelized streams, and disturbed uplands into a vibrant, species-rich ecosystem. By reconnecting the stream to its floodplain and incorporating microtopography techniques, the restoration team created a varied landscape that supports multiple habitat communities and improves groundwater infiltration—essential elements for sustaining wildlife.
The transformation of Pin Oak Forest into a high-functioning wetland complex has had profound impacts. The site now provides critical habitat for a range of species, including the state-threatened Black-crowned Night-Heron (Nycticorax nycticorax) and Red-headed Woodpecker (Melanerpes erythrocephalus). The reestablishment of native vegetation, such as pin oak (Quercus palustris), swamp white oak (Quercus bicolor), and swamp rose (Rosa palustris), has further enhanced the ecosystem, creating food sources and nesting areas for birds, amphibians, and pollinators.
By managing invasive species and allowing native flora to flourish, biodiversity has significantly increased. The restored headwater wetland system supports a delicate balance of aquatic and terrestrial life, creating a vital refuge for countless species amid an otherwise urbanized landscape.
This success story highlights how thoughtful ecological restoration can bring degraded environments back to life, providing a lasting benefit for wildlife and the surrounding community alike.
On this World Wildlife Day, the Pin Oak Forest project serves as an inspiring reminder of what’s possible when partnerships, science, and dedication converge to protect and restore critical habitats. The work done here is not just about the past—it’s about shaping a future where wildlife and people can thrive together.
At Princeton Hydro, we remain committed to advancing ecological restoration, ensuring that more landscapes like Pin Oak Forest can be revitalized for generations to come. We hope that by reflecting on the success of this project, more communities and organizations will be inspired to take action in preserving and restoring the natural world and pledge to protect the wildlife that makes our planet so extraordinary.

An ambitious project is underway to eradicate the invasive Silty Pond Mussel (formerly known as the Chinese pond mussel, Sinanodonta woodiana) from the Wickecheoke Creek Preserve in New Jersey. This critical initiative seeks to protect local ecosystems, safeguard native aquatic species, and prevent the spread of these aggressive invaders into the broader Delaware River ecosystem.
The Silty Pond Mussel was first discovered in the United States in 2010 at a former fish farm in Hunterdon County, now part of NJ Conservation Foundation’s Wickecheoke Creek Preserve. It is believed the mussels arrived as glochidia (a microscopic larval stage of some freshwater mussels) attached to the gills of bighead carp, another invasive species imported from China by the farm's previous owners. Initially overlooked and undocumented in North America, the mussels quickly established a foothold in the Preserve's ponds, threatening local ecosystems.
These invasive mussels, which can grow to the size of a small football, form high-density colonies that pose a severe threat to native organisms. This aggressive species outcompetes native mussels for nutrients and habitat, altering water chemistry in the process and drastically depleting the local ecosystem of resources essential to native plants and animals. Additionally, once the Silty Pond Mussel glochidia attach to the gills of native fish, a biological reaction occurs that ultimately kills the host fish thus preventing native mussels from completing their own life cycle on these fish hosts. This dual impact — monopolizing food and habitat resources as adults while denying native mussels access to necessary host fish — makes the Silty Pond Mussel especially harmful to local ecosystems.
Following the initial discovery, DNA testing conducted by the NJ Invasive Species Strike Team, New Jersey Endangered & Nongame Species Program, and the North Carolina State Museum of Natural Sciences confirmed the presence of this invasive species, marking the first documentation of the Silty Pond Mussel in North America. Early eradication efforts began shortly thereafter.
Since 2019, a coalition of partners has expanded these efforts and remained committed to the complete eradication of the Silty Pond Mussel species. Led by NJDEP Fish & Wildlife and including organizations such as tthe U.S. Fish & Wildlife Service, NJ Conservation Foundation, Rutgers University, NJ Water Supply Authority, U.S. Department of the Interior's Office of Restoration and Damage Assessment (ORDA) and Princeton Hydro, the project has focused on surveying waterways using SCUBA, snorkel and physical analysis; utilizing environmental DNA (eDNA) testing to detect the presence of mussels in a waterbody; and applying targeted treatments. Community engagement and education are also central to these efforts, emphasizing the importance of collaboration in tackling this ecological threat.
Geoffrey M. Goll, P.E., President of Princeton Hydro, emphasized the collaborative nature of the efforts: "This initiative exemplifies the power of partnership and innovation in tackling environmental challenges. Together, we are making significant strides in preserving our state's rich biodiversity."
The Wickecheoke Creek Preserve, home to nearly 400 native plant species and a wide variety of wildlife, includes 14 miles of streams and flows directly into the D&R Canal, which supplies clean drinking water to one million New Jersey residents. New Jersey is also home to 12 native freshwater mussel species, nine of which are classified as Endangered, Threatened, or of Special Concern, further underscoring the the urgency of preventing this aggressive invasive species from spreading. Left unchecked, the Silty Pond Mussel could disrupt one of the most biodiverse freshwater regions in the country and cause significant ecological harm. Swift action to address this invasive species is essential to protecting the Wickecheoke Creek Preserve, safeguarding native species, and preserving the health of the Delaware River watershed.
Each project partner plays an essential roles in the eradication process. Rutgers University is performing the environmental DNA (eDNA) monitoring and analyzing the results. Princeton Hydro is applying targeted treatments to the ponds where the mussels were initially detected, and, if eDNA or physical sampling reveals signs of the mussels in other water bodies, the team will extend these treatments accordingly. Using a highly specialized approach, Princeton Hydro’s licensed applicators have partnered with SePRO to apply Natrix, an EPA-registered pesticide developed specifically for managing invasive mollusk populations. The 2024 phase of the project has incorporated significant advancements in treatment design. The team’s strategy is both preventative and responsive. The project has garnered financial support from the U.S. Fish and Wildlife Service and the Delaware River Greenway Partnership through the Lower Delaware Wild and Scenic Program.
In addition to treatment, Princeton Hydro is focused on rigorous documentation and educational outreach. “It’s important for us to record every aspect of this project, not only from a scientific perspective but also for public education,” said the Princeton Hydro Director of Marketing & Communications Dana Patterson Grear. “We want to ensure this species is contained here and prevented from spreading throughout New Jersey or, worse, across the United States.” As part of these efforts, Princeton Hydro aims to share detailed information on the Silty Pond Mussel’s characteristics and identification markers. “By educating communities and environmental stakeholders on what to look for, we hope to empower rapid responses in other areas, should the species appear elsewhere,” said Patterson Grear.
As part of the project's commitment to transparency and education, New Jersey DEP Fish & Wildlife created a detailed video to showcase the silty pond mussel eradication and identification efforts. This video delves deeper into the techniques and collaborative approaches being used to address the invasive species. We encourage you to watch the video to gain a comprehensive understanding of the challenges faced and the innovative strategies employed in this groundbreaking effort.

Invasive species may be impacting your backyard without you even realizing it. These non-native plants, animals, and organisms can harm ecosystems, the economy, and even human health when they take root in areas where they don’t naturally belong.
If you missed our recent Facebook Live presentation on this important topic, don’t worry — the recording is now available for on-demand viewing! In the webinar, experts from the Princeton Hydro team - Michael McGraw, CSE, QAWB, ACE, Senior Project Manager and Senior Wildlife Biologist of Regulatory Compliance & Wildlife Surveys, and Jesse Smith, Aquatic Ecologist - provide practical tips on how to identify and manage invasive species, helping to keep your backyard and local environment thriving.
Invasive species are organisms that are not native to an area but thrive and spread aggressively, often causing harm to native ecosystems. They compete for resources, disrupt habitats, and can introduce diseases, leading to the decline of native species. Unlike exotic species, which may be non-native but do not necessarily cause harm, invasive species tend to simplify ecosystems by outcompeting native plants and animals.
A well-known example is the Emerald Ash Borer, a beetle responsible for the widespread death of ash trees across North America. Another, Phragmites australis, also known as Common Reed, is a highly invasive grass that dominates wetlands, lowering biodiversity and displacing native species. The spread of these and other invasive species can be exacerbated by human activity and even by climate change.
In their natural environment, invasive species have predators and environmental checks that keep their populations under control. However, when introduced to new habitats, they lack these natural controls, allowing them to spread rapidly. Invasive species can alter ecosystems by:
Freshwater ecosystems and wetlands are particularly vulnerable because it’s hard to contain the spread of invasives in these environments. Once established, invasive species are difficult to remove and can cause long-term damage.
The good news is that there are steps we can take to help prevent and manage invasive species in our communities. Here’s what you can do:
Educate and Share: Education is one of the most powerful tools in fighting invasives. Learn about which plants are native and beneficial to your specific region. Talk with your neighbors, community organizations, and local land managers about the importance of managing invasive species. And consider sharing educational resources like this blog and our on-demand webinar.
Reduce the Spread: Prevention is the best strategy. By planting native species, removing invasives, and avoiding the release of invasive species into the environment, you can help stop the spread.
Monitor Your Property: Routinely checking your property for invasive species is key to early detection. Reach out to local watershed organizations to get involved in monitoring efforts. Get involved with organizations focused on monitoring and protecting local lakes and waterways. In Virginia, the Smith Mountain Lake Association has launched “Dock Watch,” a community science program where volunteers collect water samples from select docks to monitor harmful algal blooms, track cyanobacteria levels, and report invasive aquatic species.
Document and Report: Learn to identify common invasive species in your area and report them to local authorities, such as your county extension office or an invasive species management team. In New Jersey, the Invasive Species Strike Team works to control the spread of these harmful organisms.
Here are some methods to consider when removing Invasive Species:

We are thrilled to announce the newest addition to our fleet: The Marsh Master® 2MX-KC-FH! This multi-functional, eco-friendly, and fully amphibious machine is specifically designed to work in wetland environments with minimal disruption to the delicate ecosystem.
One of the Marsh Master®'s primary roles is combating invasive and nuisance plant species, including the notorious non-native Phragmites australis, also known as Common Reed. Utilizing its innovative leveling and cutting mechanisms, this powerhouse of a machine efficiently knocks down and chops up sprayed or winter-weakened vegetation. Equipped with two powerful rotary blades, it effortlessly cuts through dense underbrush and tall marsh grasses, effectively controlling invasive weeds and problematic plant growth.
"We are committed to offering more non-chemical alternatives for aquatic invasive species control. The Marsh Master® 2MX-KC-FH is the second marsh buggy in our fleet," said Geoffrey M. Goll, President of Princeton Hydro. "This model is larger and more powerful, allowing us to cover more ground in a shorter period of time. Adding this machine to our fleet is an important investment in achieving our firm's environmental stewardship goals."
What sets the Marsh Master® apart is its versatility and low environmental impact. With its lightweight construction and advanced weight distribution system, it exerts low ground pressure and boasts high floating capacity. This allows the Marsh Master® to operate seamlessly on water, in deep or shallow depths, and on dry land without disturbing sensitive environments like nature preserves, wetlands, and canal banks. Its highly maneuverable design ensures easy passage through narrow channels and around hazards, making it the ideal choice for a wide range of applications.
But the Marsh Master® is not just a one-trick pony. With a wide array of tools and accessories, it can perform a variety of functions, from weed cutting and harvesting to debris removal to excavation to soil sampling.
During a recent project in Middlesex County, we put the Marsh Master® to the test to clear an area overrun with Phragmites australis. These invasive weeds not only create dense thickets unsuitable for native fauna but also outcompete local vegetation, leading to a decrease in plant diversity. Thanks to the Marsh Master®'s efficient cutting and rolling capabilities, we were able to expose the marsh plain and get it ready for planting of native vegetation in the Spring. This is just one example of how the Marsh Master is making a tangible difference in restoring delicate ecosystems.
Through a combination of prevention, early detection, eradication, restoration, research and outreach, we can protect our native landscapes and reduce the spread of invasive species. Learn more about our invasive species removal and restoration services.
In Warrington Township, Pennsylvania, an innovative ecological uplift initiative is underway at Lion's Pride Park. This project aims to transform a stagnant pond, overrun with invasive species and plagued by water quality issues, into a thriving wetland mosaic. This endeavor, a collaborative effort between Warrington Township, Princeton Hydro, and other stakeholders, promises to not only revitalize the natural environment but also enhance community access and education within the park.
Spanning 47 acres, Lion's Pride Park serves as a green oasis within the Township, offering a range of recreational and educational opportunities for visitors of all ages and abilities.
The pond within the park was in urgent need of restoration - heavy storm events caused the pond to overflow, which created flooding conditions in the park. The local native biodiversity was being threatened by nusiance and invasive species like water chestnut (Trapa natans). The photos below were taken in April 2020.
Princeton Hydro began in 2020 with site investigation and field surveys, including:
The most substantial component for the restoration project was the conversion of the existing pond to an emergent wetland complex to provide habitat for a wide variety of native species. Using the completed existing conditions reports and surveys, Princeton Hydro prepared the conceptual design plan that informed the entire restoration process.
Princeton Hydro Regulatory Compliance & Wildlife Surveys Project Manager Emily Bjorhus, PWS spearheaded the regulatory program for the project, navigating approvals from the Pennsylvania Department of Environmental Protection (PADEP), the U.S. Army Corps of Engineers (USACE), and the Bucks County Conservation District. The permitting process laid the groundwork for the smooth implementation of this design-build restoration project.
The restoration work encompassed various stages, from earthwork and vegetation planting to the installation of ADA-compliant pathways and informational signage. Some of the key project elements, include:
Channel stabilization: Stabilizing the channels within the park, addressing erosion issues, enhancing water flow dynamics, and promoting the establishment of diverse aquatic habitats.
Berm construction: Installing berms to enhance wetland habitat and promote natural floodplain connectivity, contributing to the resilience of the ecosystem to flooding events.
Native vegetation planting: Reintroducing native wetland and riparian plant species to enhance biodiversity and create habitat corridors for wildlife within the park. Planting is expected to take place in the Spring.
Boardwalk installation: Constructing a 6-foot-wide ADA-compliant boardwalk that spanned approximately 230 linear feet, providing visitors with accessible pathways to explore the restored wetland areas.
Through these strategic interventions, the Lion's Pride Park Ecological Restoration Project aims to not only rejuvenate the ecological integrity of landscape but also enrich the recreational and educational experiences of the community. The project, which is slated for 100% completion this Spring, will totally transform the landscape into a diverse wetland complex that fosters native wildlife habitat, mitigates water quality concerns, reduces nonpoint source pollutants discharged to downstream waters, and provides accessible pathways and observation platforms so all community members may enjoy and learn from this restored aquatic setting.
The reclaimed wetland provides additional bird and pollinator habitat and offer visitors a diverse ecosystem to learn from within the park. By fostering a deeper connection to nature and promoting environmental stewardship, this project exemplifies the transformative power of ecological restoration in creating vibrant, sustainable communities.
On March 23, at the 2024 Watershed Congress hosted by the Delaware Riverkeeper Network, Emily will be presenting about the Lion's Pride Park Ecological Restoration Project. Her presentation will offer insights into the regulatory approval and permitting process, takes a deeper dive into the restoration strategies, and showcases the ecological significance of the project.

The Lake Champlain Basin encompasses 8,000 square miles of mountains, forests, farmlands, and communities with 11 major tributaries that drain into Lake Champlain, ranging from 20 miles to 102 miles in stream length. The Vermont and New York portions of the Lake Champlain basin are home to about 500,000 people, with another 100,000 people in the Canadian portions of the watershed. At least 35% of the population relies on Lake Champlain for drinking water.
The Lake Champlain basin is threatened by a large number of non-native aquatic invasive plant and animal species and pathogens. The Champlain Canal, a 60-mile canal in New York that connects the Hudson River to the south end of Lake Champlain has been identified by natural resources scientists and managers as a major pathway by which non-native and invasive species can invade Lake Champlain.
Aquatic invasive species that are present in the surrounding Great Lakes, Erie Canal, and Hudson River (e.g. hydrilla, round goby, Asian clam, quagga mussel, Asian carp, and snakehead) are a threat to Lake Champlain.
Once these harmful aquatic invasive species enter the lake and become established, they compete with and displace native species, severely impacting water quality, the lake ecosystem and the local economy. Infestations of these non-native invasive organisms cost citizens and governments in New York, Vermont, and Quebec millions of dollars each year to control and manage.
Aquatic invasive species (AIS) infestations reduce the recreational and economic health of communities in the Basin by choking waterways, blocking water intake pipes, outcompeting native species, lowering property values, encrusting historic shipwrecks, and ruining beaches. Additionally, they are known to decrease biodiversity and change the structure and function of ecosystems by displacing native species, transporting pathogens, and threatening fisheries, public health, and local or even regional economies.
A study of the Champlain Canal was completed by the U.S. Army Corps of Engineers, New York District, in partnership with the Lake Champlain Basin Program (LCBP), New York State Department of Environmental Conservation (NYSDEC), and New York State Canal Corporation (NYSCC), the non-Federal sponsor, New England Interstate Water Pollution Control Commission (NEIWPCC), HDR Inc, and Princeton Hydro. The main purpose of the "Champlain Canal Aquatic Invasive Species (AIS) Barrier Phase 1 Study" was to compare the costs, benefits, and effectiveness of different management alternatives that could best prevent the spread of aquatic invasive species between the Hudson and Champlain drainages via the Champlain Canal.
The primary focus of this study was located at the summit canal between locks C-8 and C-9, as this location is the natural point of separation for the watersheds. This is where (the summit) the Glens Falls Feeder Canal supplies Hudson River water to the height of the Champlain Canal to maintain water levels for navigability that flows south back to the Hudson, but also north and into the Champlain drainage.
The scope of the study included analyzing alternatives for a dispersal barrier on the Champlain Canal and evaluating options to prevent the spread of AIS, including fish, plants, plankton, invertebrates, and pathogens. The study examined potential physical and mechanical modifications to separate the two basins to prevent movement of aquatic nonnative and invasive species between the Hudson River and Lake Champlain. Physically and mechanically modifying the canal was evaluated to be the most effective at reducing the inter-basin transfer of invasives that might swim, float, or be entrained through the system, and it was found to be the most effective protection against all taxa of aquatic nonnative and invasive species.
Princeton Hydro’s main role was the initial administration of the project and development of a species inventory. This species inventory of the Champlain Canal included native and non-native aquatic species and potential aquatic invasive species that are threatening to become invasive to the Canal. Dispersal methods of the species were also evaluated to inform an Alternative Analysis. The overall study includes a Cost Benefit Analysis and Final Recommendations report of the Alternatives.
The project team utilized a standard, three-step approach for developing alternatives: 1) gather general information about measures that may contribute to a solution to the problem, 2) narrow the list of measures through application of project-specific constraints, and 3) develop alternatives by combining measures that reduce or eliminate the cross-basin transfer of invasive species.
The alternative to construct a physical barrier across the canal was identified as the most effective approach to limiting the transfer of non-native AIS, and would address all taxa – plants, animals, plankton, viruses and pathogens. This alternative would include the installation and management of a large boat lift, a boat access ramp, a boat cleaning station, and repairs to the existing lock seals.
At the Glens Falls Feeder Canal cleaning station and boat lift area, small and large boats would be cleaned prior to being placed back in the water on the other side, and the wash water would be captured and stored to be sent to a treatment plant. This alternative provides the most effective protection from AIS crossing between the Hudson River and Lake Champlain Watersheds, but it does remove the possibility of large commercial barges traveling the full length of the canal. A larger loading/offloading and cleaning facility would be required for commercial shipping vessels to be granted continued access along the canal.
In a press release from the U.S. Army Corps of Engineers announcing the completion of the Phase I Study, Colonel Matthew Luzzatto, Commander, U.S. Army Corps of Engineers, New York District was quoted as saying, “This is an important milestone in moving forward towards a more healthy ecosystem for the Lake Champlain and Hudson River Watersheds. These two watersheds are vital to the lives and wellbeing of millions of residents of New York and Vermont. This study will have a positive impact on the overall economic and ecological health of the Lake Champlain Region, this is a win-win-win for all interested parties."
Following the completion of the Phase I portion of the study, the Phase II portion of the study will consist of detailed analyses of alternatives including engineering studies such as hydrologic evaluation for stream capacities / canal makeup water, geotechnical investigations at the location of the proposed concrete berm, topographic / utility survey as well as boundary / easement survey, vessel traffic studies through the canal, detailed cost estimates, and NEPA compliance. Once Phase II is complete and funding is appropriated, the Canal Barrier Project will be closer to construction.
Before you go, always do your research, educate yourself on fishing laws and regulations, and make sure your fishing license and boat registration is current. Check your local area for information on season dates, size requirements, possession limits, permit requirements, area closures, and other guidelines. These laws protect fish and other aquatic species to ensure that the joys of fishing can be shared by everyone well into the future. The New York State Department of Conservation publishes a very informative Freshwater Fishing Regulations Guide every year. Click here to review the 2022 guide.
Check out this interactive map from TakeMeFishing.org to find great fishing and boating spots in your area, including fish species you can expect to find, logged catches and fishing forecasts.
Reduce the spread of invasive species by thoroughly washing your gear and watercraft before and after your trip. Invasives come in many forms – plants, fungi, and animals – and even those of microscopic size can cause major damage. To learn more about invasive species, read our blog:
Use artificial lures or bait that is native to the area you’re fishing in. Live bait that is non-native can easily introduce invasive species to water sources and cause serious damage to the surrounding environment. Always do your part to keep our precious waterbodies clean and fisheries healthy! Opt for biodegradable fishing lures, properly dispose of your lures, make sure your lure is secure, and check your bait often. Click here for more info on eco-friendly bait and fishing gear.
Before you head out for a day of fishing, familiarize yourself with catch and release best practices. Always keep the health of the fish at the forefront of your activities by using the right gear and employing proper techniques.
NOAA Fisheries says, "Catch and release is a great conservation strategy, but simply letting a fish go does not guarantee it will live. The actions you take before, during, and after you land a fish can improve its chances of survival, keep fish stocks healthy, and keep fishermen fishing." Visit their website for more info and helpful tips.
Stay on designated paths to avoid disrupting sensitive and protected areas, like wetlands, shorelines, stream banks, and meadows. Disturbing and damaging these sensitive areas can jeopardize the health of the many important species living there. We recently worked with the Watershed Institute to present a workshop about stream bank restoration in communities and backyards; click below to watch.
Always, pack out your trash! Bring a bag with you to easily carry out your trash and any litter you may find. Never leave behind fishing line, fish entrails, or bait. Before a fishing trip or any outdoor adventure, familiarize yourself with the seven principles of Leave No Trace and spread the good word to others!
