Summary
Built in 1943, this earth dam stands at a height of 29 feet and serves multiple purposes including fire protection, stock watering, and small fish pond maintenance. With a storage capacity of 157 acre-feet, Brewer plays a crucial role in providing water supply for various needs in the area.
Despite its low hazard potential, Brewer's condition assessment is marked as poor, indicating a need for maintenance and potential upgrades. The dam has a spillway width of 30 feet and is equipped with a single valve as its outlet gate. The last inspection in August 2021 revealed the need for improvements, highlighting the importance of regular monitoring and upkeep to ensure the safety and effectiveness of the structure.
Climate and water resource enthusiasts interested in the management and maintenance of dams like Brewer in Wyoming can find valuable insights in the data provided. Understanding the regulatory framework, inspection frequency, and potential risks associated with aging infrastructure like Brewer is crucial for ensuring the sustainable use of water resources and maintaining the safety of communities that rely on these structures for various purposes.

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.
