Summary
This gravity dam, completed in 1977, serves primarily for recreational purposes and boasts a structural height of 16 feet and a storage capacity of 1500 acre-feet. With a surface area of 130 acres and a drainage area of 2.5 square miles, this lake offers a picturesque setting for outdoor activities such as boating, fishing, and birdwatching.
Managed by the Wisconsin Department of Natural Resources, Half Moon Lake is regulated, inspected, and enforced to ensure its safety and sustainability. Despite its low hazard potential, the lake is considered to have a very high risk due to its critical importance to the local community and environment. The dam's controlled spillway and maximum discharge capacity of 2082 cubic feet per second contribute to its efficient water management system, while its location as a tributary to Sherman Creek adds to the overall ecological significance of the area.
With its serene surroundings, recreational opportunities, and strategic management, Half Moon Lake stands as a testament to the harmonious coexistence of water resources and climate sustainability. Whether you're a water sports enthusiast, a nature lover, or a climate advocate, this picturesque destination in Eau Claire, Wisconsin, offers a captivating blend of beauty and functionality for all to enjoy.

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.
