Understanding the Role of Floodplain Management Floodplain management is a multidisciplinary practice that integrates planning, engineering, ecological science, and public policy to reduce flood risk while preserving the natural functions of riverine and coastal systems. At its core, it involves understanding how water moves across a landscape, identifying areas vulnerable to flooding, and implementing measures that protect people, infrastructure, and ecosystems. Floodplains provide a range of essential functions. Hydrologically, they convey, store, and infiltrate water during storm events, supporting natural flood attenuation, erosion control, and groundwater recharge. Ecologically, they contribute to biodiversity by providing habitat, migration corridors, and spawning areas for fish and wildlife. From a community perspective, well-managed floodplains can offer recreational value, improve water quality, and enhance the aesthetic and economic vitality of local neighborhoods. Modern floodplain management relies on both structural and non-structural approaches. Structural measures may include engineered solutions such as levees, floodwalls, culvert improvements, or stormwater system upgrades. Non-structural tools often involve land-use planning, flood-resilient building standards, conservation of open space, and community engagement programs that help residents understand risk and adopt best practices. Princeton Hydro works with municipalities, state agencies, nonprofit organizations, and watershed groups to develop and implement comprehensive floodplain management strategies across the region, emphasizing strategies that balance flood risk reduction with ecological enhancement, ensuring that floodplain management supports both resilient communities and healthy, functioning watersheds.

Within the intricate network of aquatic ecosystems, the American shad stands as a captivating enigma. This intrigue was recently explored in a webinar hosted by The Watershed Institute titled “The Mysterious World of the American Shad and Work to Bring Them Back to Our Waterways.” Led by The Watershed Institute’s Executive Director Jim Waltman and Princeton Hydro’s Senior Technical Director in Engineering and American shad expert Dr. Clay Emerson PE, CFM, the webinar explored the complex dynamics surrounding this iconic species, including its historical significance, unique migration patterns, and conservation efforts.
As the American shad embark on their annual upstream journey for spawning, the timing is especially poignant for a closer examination of this vital species and an exploration of strategies to safeguard and revive their populations. We invite you to enjoy our blog, which encapsulates the webinar's key insights, and to watch the full recorded session made available by The Watershed Institute.
American shad (Alosa sapidissima) are the largest members of the herring family. Their closest relatives are herring, sardines, and menhadens. They are an anadromous fish species, like salmon and steelhead (Oncorhynchus mykiss), that live most of their life in the ocean and migrate to freshwater rivers and streams to spawn. The American shad migration routes span vast distances, from the St. Johns River in Florida to the St. Lawrence River in Quebec, showcasing their tenacity and adaptability.
Not only do American shad undertake astonishingly long journeys to spawn, they also showcase distinctive migratory behaviors. Unlike many other anadromous species, these resilient shad can complete multiple round trips from freshwater to the ocean over their lifespan, challenging the conventional notion of 'one and done' spawning observed in Pacific salmon (Oncorhynchus) and sea lamprey (Petromyzon marinus).
Young shad will remain in the rivers where they hatched for several months. Migration out to the ocean typically occurs in late summer in the south, and early fall in the north, typically when the shad are 3-4 inches in size. Then, after 3-6 years of growth at sea, the shad migrate back to fresh water to spawn. Some shad make the journey to their spawning grounds 5-6 times over the course of their lifetime. Shad’s affinity for their birthplace adds a fascinating layer to their story. Approximately 95% of shad return to the rivers where they were hatched, with only 5% straying to unfamiliar waters to spawn.
American shad's unique hearing abilities are another noteworthy aspect. Endowed with specific biological features, shad exhibit exceptional sensitivity to water movements and noise, particularly attuned to sounds like clicks and echolocation. This acute sense plays a vital role in navigating their environment and evading predators such as dolphins.
Such intriguing characteristics make the American shad not only a vital component of aquatic ecosystems but also a subject of admiration and study among enthusiasts and conservationists alike.
Throughout history, American shad have held a vital place in the cultural heritage and economic prosperity of the United States, earning them the esteemed title of "America's Founding Fish.” Within the Delaware River region, these fish were not merely sustenance but also integral to the fabric of indigenous Lenape culture. During the annual shad migration, rivers and streams overflowing with these prized fish provided essential nourishment and served as valuable fertilizer. Interestingly, in various Native American tribes, folklore depicts the shad as originating from the porcupine, likely owing to the fish's notably bony structure.
In later American history, the significance of shad persisted. Renowned painter Thomas Eakins immortalized the tradition of shad fishing in his iconic 1881 masterpiece "Shad Fishing at Gloucester on the Delaware River," while the state of Connecticut elevated the shad to the status of state fish, further cementing its place in American heritage.
Fishing for American shad was among the earliest established industries on the coast of North America, once providing abundant and affordable nutrition to the populace. However, the shad population peaked in the 1940s before experiencing a dramatic decline to its current depleted state.
Despite these challenges, the American shad perseveres as a symbol of resilience. Festivals along the Atlantic Coast, such as the Annual ShadFest in Lambertville, New Jersey, celebrate these fish while also advocating for their protection. Recognizing the historical importance of shad underscores the pressing responsibility to safeguard and preserve our natural heritage for future generations.
The construction of dams, historic overfishing, and pollution have all played significant roles in the decline of American shad populations.
Dams along the East Coast block access to vital spawning grounds. Currently, a staggering 40% of American shad habitat is obstructed by these barriers, resulting in the loss of more than a third of the population. By removing outdated dams that have outlived their usefulness, we not only improve water quality and natural habitat for myriad species but also reconnect shad to their historic spawning grounds.
Additionally, shad fall victim to inadvertent bycatch in various ocean fisheries. Pollution in our rivers and water quality issues emerge as another critical concern along with fluctuating water temperatures and dissolved oxygen levels that disrupt shad behavior and crucial life cycle events such as migration and spawning. Compounding these issues are the menacing presence of invasive species, which outpace shad in numbers and deplete food resources, posing a significant obstacle to their recovery efforts.
Amidst these challenges, there is hope. River restoration efforts, dam removals, and fish passage projects throughout the East Coast stand as beacons of progress.
Removing obsolete dams, culverts, and other man-made barriers; the implementation of fish passage projects; and river habitat restoration initiatives have shown promising results in directly aiding shad and other migratory aquatic species populations. Highlighted below are a few examples of dam removal initiatives that immediately yielded positive results:
The Nature Conservancy in New Jersey and Princeton Hydro are leading the removal of three outdated dams on the Paulins Kill River: the Columbia Lake Main and Remnant Dams (completed 2019), the County Line Dam (completed 2021), and Paulina Dam (slated for completion 2024). This collaborative effort will reconnect 45 miles of mainstream and tributaries for migratory fish species like American shad. The Columbia Lake Dam removal, New Jersey's largest to date, began in July 2018 and showed promising results even before 100% completion. By April 2019, American shad were spotted 10 miles upstream from the former dam site for the first time in over a century, showcasing the resilience of this incredible species and the success of conservation initiatives.
In November 2016, the Musconetcong Watershed Association (MWA) and Princeton Hydro completed the Hughesville Dam Removal, opening up six miles of the Musconetcong to migratory fish. In the Spring of 2017, schools of American shad were observed above the dam, five miles from the river's confluence with the Delaware River. After an absence of over 250 years, American shad made a triumphant return to the Musconetcong River sparking hope for the future.
Shad serve as a crucial benchmark species, offering valuable insights into the ecological health and diversity of our waterways. Conservation endeavors that facilitate the resurgence of the American shad not only represent a thrilling triumph but also stand as proof-positive of our capacity to assist migratory fish in reclaiming their natural habitats. In doing so, we safeguard their future and preserve the places they call home.
By understanding the biology, historical significance, and primary challenges of the American shad, we can work towards sustainable solutions that benefit both shad populations and the broader ecosystem. We invite you to delve deeper into the fascinating world of American shad by watching the full webinar:

The Watershed Institute's next "Technical Friday" webinar, which is free to attend, will focus on "Stormwater Design: Myths and Misconceptions." One of the most complicated aspects of a new development application is designing the stormwater management infrastructure. It is also one of the most complex parts of reviewing applications before New Jersey’s land use boards. While stormwater management is a difficult and complex issue, it is vital to the health and wellbeing of New Jersey communities and residents. The state's 2023 Municipal Separate Storm Sewer System (MS4) permit puts front and center New Jersey's obligation to review the stormwater issues caused by land development. Better design submissions will assist in reaching this goal and may speed up the process of review and approval.
On December 8 from 10 am - 12 pm, join Gabriel Mahon, PE, Bureau Chief of the Bureau of NJPDES Stormwater permitting and Water Quality Management and Dr. Clay Emerson, PhD, PE, CFM from Princeton Hydro as they examine some of the common issues they uncover in stormwater management proposals and provide guidance on incorporating best practices and submitting designs that successfully address New Jersey's stormwater management goals.

March 2, 2021 is the deadline for New Jersey’s municipalities to comply with the new stormwater management ordinances laid out in the New Jersey Stormwater Management Rule (N.J.A.C. 7:8).
The New Jersey Department of Environmental Protection (NJDEP) revised the rule last year to now require construction projects to include green infrastructure in order to meet the three performance criteria that NJDEP sets forth for stormwater management. The new rule gives local governments an opening to revise their existing stormwater management ordinances to better manage flooding and improve compromised water quality.
The rule defines green infrastructure as, “a stormwater management measure that manages stormwater close to its source by: treating stormwater runoff through infiltration into subsoil; treating stormwater runoff through filtration by vegetation or soil; or storing stormwater runoff for reuse.”
The pre-existing rule required that major developments incorporate nonstructural stormwater management BMPs/strategies to the “maximum extent practicable” to meet their criteria. The amended rule not only gives specific suggestions for the kind of BMPs it’s looking for by adding a definition of green infrastructure, but it also makes those BMPs/strategies a requirement for compliance with the rule’s minimum standards. Also included in the rule are tables outlining the application of each type of stormwater BMP.
Another update to the rule is that motor vehicle surfaces are now incorporated into the definition of major development. The amended rule requires these motor vehicle surfaces to have 80% total suspended solids (TSS) removal in order to maintain water quality. These surfaces include standard pavement drive/parking areas and gravel and dirt drive/parking areas, according to the rule. However, the rule does not require water quality control for runoff from other impervious surfaces that are not traveled by automobiles, such as rooftops and sidewalks, or other paved walkway areas.
New Jersey municipalities need to comply with the new standards and the ordinances must be in effect by March 2nd, 2021. To make this transition a bit smoother, NJDEP released a revised Model Ordinance in Appendix D of the NJ Stormwater BMP Manual to act as a sample for municipalities to follow when adopting these new regulations.
The Watershed Institute also drafted its own Model Ordinance to help municipalities go beyond the updated rule and strengthen protections to benefit the environment. The Model Ordinance builds on the state’s baseline requirements with the following enhancements:
At the end of last year, The Watershed Institute held a webinar about the state’s new Green Infrastructure rule. The webinar, attended by 240 people, included three presentations that provided a detailed look at the NJDEP’s rule updates and the steps needed for local governments to comply. Click below to watch the full webinar:
The presentations, given by the following green infrastructure experts, are also available to view in full:
At Princeton Hydro, we recognize the benefit of green infrastructure and we’ve been incorporating it into our engineering designs since before the term was regularly used in the stormwater lexicon. We’ve been following the rule amendments very closely, and, last year, we developed the following blog to help folks garner a deeper understanding of green infrastructure, interpret the rule updates, and break down the complexities of the stormwater guidelines:
