Summary
Built in 1950, this earth dam stands 16 feet tall with a hydraulic height of 13 feet, providing recreational opportunities in the area. With a storage capacity of 165 acre-feet and a normal storage level of 149 acre-feet, the dam spans 480 feet in length and covers an area of 10 acres.
Situated on the Little Rockfish Creek, Lake Williams Dam serves as a low hazard structure with a satisfactory condition assessment as of November 2013. While not regulated by the state, the dam undergoes regular inspections to ensure its safety and integrity. With a maximum discharge capacity of 150 cubic feet per second, the dam contributes to the local drainage area of 9408 acres, making it a significant water resource in Cumberland County.
Managed by private owners, Lake Williams Dam plays a vital role in providing recreational opportunities for the community while also serving as a source of water storage. Its strategic location and design highlight the importance of maintaining dam safety and monitoring its condition to mitigate any potential risks associated with its operation. Climate and water resource enthusiasts can appreciate the unique features and significance of Lake Williams Dam in the local ecosystem.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
