Lake Williams Dam

The York Water Company (Owners)
Gannett Fleming (Designers)
Kinsley Construction (Contractor)

Nestled in the heart of York County, Pennsylvania, the Lake Williams Dam was built by The York Water Company in 1912 to support a growing town's need for manufacturing, fire protection, and drinking water. The original earthen embankment dam was constructed using nascent steam technology and included a concrete core wall, a trailblazing feature for a dam of the time.

In recent years, the Pennsylvania Department of Environmental Protection updated its dam safety regulations, including probable maximum flood (PMF) conditions, which rendered the original dam's spillway undersized. Despite the dam's structural soundness, the requirement to safely pass a PMF of over 107,000 cubic feet per second — an exponential increase to its designed capacity and substantially greater than the 1972 storm of record — prompted a robust engineering response. While addressing the discharge capacity, York Water also seized the opportunity to concurrently improve other elements of the dam, such as the lack of underdrainage in the original spillway, the spillway's foundation on embankment fill as opposed to bedrock, the absence of filters downstream of the spillway, and aging bascule gates.

While working under an expedited schedule, the project team, which included owner York Water, engineer Gannett Fleming, and contractor Kinsley Construction, reimagined a dam that would meet modern design, safety, and performance standards and ensure its continued role in providing essential water services for another century.

Key to the rehabilitation was the introduction of a labyrinth spillway built with a roller-compacted concrete gravity section founded on bedrock and designed to handle significantly higher discharge capacities than the original dam. Other major structural enhancements include a non-overflow gravity section and advanced seepage management features. These improvements were rooted in a design process that valued thorough analysis, ingenuity, and respect for the dam's historical elements, including its original concrete core wall.

The Lake Williams Dam rehabilitation was also designed to minimize environmental impacts, enhancing ecological conservation by creating additional wildlife habitats and aquatic environments. This included introducing a 1-foot pool elevation increase, which added more than 60 million gallons, generating 3 acres of open-water habitat, and forming islands to support diverse and protected species. The project also focused on aesthetic improvements, such as concealing exposed dam armoring with locally sourced topsoil and reshaping the landscape to blend with the natural surroundings, further underscoring York Water's commitment to environmental and visual harmony.

Structurally complete by December 2023, it is one of the few structures of its kind and the only one in Pennsylvania designed to this standard. This project exemplifies how contemporary engineering and proactive planning can transform 20th-century infrastructure into modern models of safety, functionality, and environmental stewardship.

Kingston Water Department
Cooper Lake Dam Rehabilitation

The Cooper Lake Dam is an earthen embankment dam 460-ft long and 45-ft high that impounds a 3,700 acre-foot reservoir. The dam is owned by the City of Kingston Water Department (KWD) and it is the primary water supply source for Kingston, NY. KWD undertook a rehabilitation of Cooper Lake Dam to protect and preserve their water supply source through the 21st century.

Schnabel Engineering and sub-consultant CDM Smith worked with the KWD to develop a comprehensive rehabilitation design to address long-needed operational and dam safety improvements, contributing to compliance with New York state dam safety regulations and planning for future water storage needs. The project addressed spillway capacity limitations and embankment slope stability concerns and would replace and upgrade inoperable water supply and outlet works system components. The project was completed while Cooper Lake continued to serve as the city’s primary water supply source, which required close coordination and detailed sequencing during construction to balance water supply and construction risks. Construction on the project began in July 2021 and reached substantial completion in December 2023.

The rehabilitation project was the largest ever undertaken by the KWD and was completed under budget at a total design and construction cost of $18M. The project was primarily funded with low interest financing obtained through the Drinking Water State Revolving Loan Fund (DWSRF), supplemented by a $3M Water Infrastructure Improvement Act (WIIA) grant, and a $100K FEMA High Hazard Potential Dam (HHPD) grant. This is the first project in New York to receive DWSRF funding for Dam/Reservoir Rehabilitation under the Environmental Protection Agency’s Class Exception for water supply dams. Previously, projects involving the rehabilitation of dams and reservoirs were prohibited from using DWSRF funding mechanisms. The Class Exception established criteria that must be met to make dam and reservoir projects eligible for DWSRF funding and Kingston’s successful application of this exception has opened the opportunity for water supply dam owners across New York and the nation to pursue similar funding for their dam rehabilitation projects. Because of the extraordinary nature of the funding, KWD and Schnabel staff hosted a project site tour for the New York State Environmental Facilities Corporation’s board of directors and other key staff as a visual demonstration of the benefits of the project funding.

Representative John Thomas Lamar III
District 8, Mississippi

As an active representative for his district, Rep. Trey Lamar (R) met with multiple owners of high hazard dams and heard a common theme — dam owners wanted to meet the required safety standards, but the cost of rehabilitation to bring those dams into compliance was not something they could handle without assistance. The FEMA Rehabilitation of High Hazard Potential Dam Grant Program had just been implemented, but the challenges related to eligibility requirements and the small amount of funding coming into the states were just not enough to trickle to these smaller high hazard dams.

Recognizing the challenge, Lamar brought forth House Bill HB1730 for formation of the Mississippi Dam Safety Fund. As the Mississippi House Ways and Means Chairman, Lamar championed the proposal which passed on May 28, 2020. In the first year, the bill passed through legislature with an allocation of $1,000,000. In 2021, Lamar pressed for more funding, bringing another $1,000,000 to the program, followed by $2,000,000 in 2022 and $2,000,000 in 2024.

Lamar's efforts led to the rehabilitation of 15 high hazard dams during the 2021 funding cycle and another 14 in the 2022 funding cycle, taking those 29 dams from poor or unsatisfactory condition to satisfactory and in full compliance with the Mississippi High Hazard Dam standards. The long-term impacts of this program will continue to bolster efforts to protect downstream lives and property for years to come.

City of Pelican Rapids, Minnesota

The City of Pelican Rapids completed removal of the Pelican Rapids Dam, a high hazard dam in poor condition, in the fall of 2023. However, the decision to remove the dam was not easy.

The Pelican Rapids Dam, along with the massive statue "Pelican Pete" (known as the "world's largest pelican") has been a focal point in town for decades. The dam has been in place in some form since the 1870's. In 2016, failure of a portion of a masonry wall on the downstream side of the dam caused the City of Pelican Rapids to start the process of deciding what to do with the aging structure. The reservoir was drawn down using the old hydropower infrastructure to inspect the dam and reduce the risk due to the collapsed masonry wall, but the drawdown resulted in sinkholes developing next to the powerhouse.

In 2017, a traditional state dam safety grant requiring a 50/50 cost-share kick-started the pre-design work. Over the next two years, the city and Minnesota Department of Natural Resources held public meetings to present ecologically friendly alternatives to dam repair. During the first few public meetings, community members expressed objections to the proposition but as the community was provided information and time, they became more receptive to the idea of dam removal. In 2019, the city decided to remove the dam, and in 2020, the city of 2,600 people received a large, no cost-share grant related to the restoration and enhancement of fish habitat. The grant was sourced from a state-wide three-eighths cent sales tax used to protect, enhance, and restore Minnesota's lakes, rivers, streams, and groundwater. The City of Pelican Rapids worked closely with the Minnesota Department of Natural Resources to develop a project meeting the goals of the grant.

The goals of the project included providing safety to downstream residents from dam failure, restoring critical habitats in the Pelican River for aquatic species, improving the biodiversity and species richness within the Pelican River, minimizing dam maintenance and other associated costs, providing more recreational opportunities to the public, and improving the overall aesthetics of the area. The completed project provides tourism, scenic views, fishing opportunities, and kayaking/canoeing capabilities to locals and the surrounding area. The project also provided fish passage that was previously obstructed by the dam.

Pocatello, Idaho

In the Spring of 2023, the National Weather Service (NWS) was instrumental in helping to provide information regarding runoff for the winter’s abnormally heavy snowpack in Southeast Idaho and Northern Utah. The NWS Pocatello Office communicated to first responders and emergency personnel the urgency of erosion that was occurring in the spillway at the Portneuf Dam (Chesterfield Reservoir) during the early morning hours of May 31, 2023. Despite the dam’s existing Emergency Action Plan containing outdated and inaccurate contact information, the NWS successfully notified individuals and organizations of the severity of the situation. Through their combined efforts, a catastrophic breach of the dam and uncontrolled release of 20,000 acre-feet of water was successfully averted.

Accepting this year’s award on behalf of the NWS Pocatello Office are Vernon Preston (Meteorologist-in-Charge) and Tim Axford (Warning Coordination Meteorologist). On that May morning, they contacted the state dam safety program, noting that continued undercutting of the dam’s concrete spillway would likely develop into a complete dam breach without an immediate response. Through their office’s communication efforts and direct onsite support with state officials and emergency managers, changes in flows into the reservoir averted a catastrophe. Thanks to the collaborative approach, officials and emergency managers could exercise their emergency action plans and make adjustments in case a future situation arises.
