Summary
This private dam, completed in 1950, stands at a height of 17 feet with a hydraulic height of 12 feet. The dam spans 1423 feet in length and has a storage capacity of 125 acre-feet. Despite having a low hazard potential, the dam is regularly inspected and maintained to ensure its structural integrity.
Michaels Dam is situated on Michaels Draw, a river/stream in Edgemont, SD, approximately 36 miles away. The dam is under the jurisdiction of the State of Wyoming and regulated by the State Engineer's Office. It is inspected every five years, with the last assessment conducted in June 2019, indicating a fair condition. The dam's emergency action plan status, risk assessment, and inundation maps are currently unknown, but the dam's overall risk management measures are being continuously evaluated.
Owned privately, Michaels Dam provides essential water resources for fire protection and agricultural purposes in the area. With a primary purpose of providing water for various uses, this earth dam plays a crucial role in supporting local communities and ecosystems. Enthusiasts of water resources and climate will find Michaels Dam a fascinating structure to study and monitor for its impact on the surrounding environment and water availability in the region.

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.
