Summary
Windy Point, located in Washakie, Wyoming, is a federal-owned earth dam that serves as a crucial water supply structure along the Grassy Draw river. Standing at 30 feet high and with a length of 210 feet, this dam has a storage capacity of 50 acre-feet, making it an essential resource for maintaining water levels in the region. Despite its low hazard potential and fair condition assessment, the dam is inspected every 5 years to ensure its continued safety and functionality.
Managed by the Omaha District of the US Army Corps of Engineers, Enl. Windy Point is regulated by the Wyoming State Engineer's Office and meets all state permitting and inspection requirements. The dam's uncontrolled spillway has a width of 45 feet, providing a means for excess water to be safely released during high flow events. With a moderate risk assessment rating and a history of fair condition, Enl. Windy Point stands as a reliable water resource structure in the region, playing a vital role in water supply management for the surrounding communities.

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.
