Summary

Completed in 1975 by the US Army Corps of Engineers, the dam serves primarily for flood risk reduction while also providing benefits for fish and wildlife, recreation, and water storage. With a structural height of 67 feet and a hydraulic height of 56 feet, the dam has a maximum storage capacity of 14,000 acre-feet and a surface area of 392 acres.

The dam poses a high hazard potential and is subject to regular inspections and risk management measures by the US Army Corps of Engineers. To address flood risks associated with the dam, the Corps monitors its condition, prioritizes maintenance activities, and collaborates with local emergency managers and the public to ensure preparedness in case of a dam-related emergency. The emergency action plan for the dam is regularly updated, and maintenance and repairs are conducted as needed to ensure the dam's functionality and structural integrity. Despite the dam's mitigation efforts, the Corps acknowledges that dams do not eliminate all flood risks, and issues may arise during severe weather events or when water levels exceed storage capacity.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
