Summary
The earth dam stands at a height of 43 feet, providing a storage capacity of 1800 acre-feet for the surrounding area. Despite its critical role in supporting local wildlife, the dam's condition remains unrated, raising concerns about its long-term stability.
Located in Blaine County, Cow Creek serves as a vital resource for the region, offering essential support for fish and wildlife populations. However, with no recent inspection date recorded and limited information on risk management measures, there is a pressing need for increased monitoring and maintenance to ensure the dam's continued functionality. As climate change impacts water resources, proactive steps must be taken to safeguard Cow Creek and its surrounding ecosystem for future generations.
As water resource and climate enthusiasts, it is imperative to advocate for the proper care and oversight of structures like Cow Creek to mitigate potential hazards and ensure the sustainability of vital habitats. By promoting responsible management practices and investing in regular inspections and maintenance, we can help protect these essential resources and support the resilience of our changing environment.

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.
