Summary
Situated on the Hi-Water Draw river, this earth dam stands at a height of 25 feet and spans 258 feet in length, providing a storage capacity of 20 acre-feet. Classified as having a low hazard potential and fair condition assessment, this structure has undergone inspections every 5 years, with the last assessment conducted in May 2019.
Managed by the U.S. Army Corps of Engineers' Omaha District, Hi-Water's spillway type is uncontrolled, with a width of 30 feet. The dam is regulated and permitted by the Wyoming State Engineer's Office, showcasing the state's commitment to ensuring the safety and functionality of water resource infrastructure. Despite being labeled as moderate risk level (3), the dam's risk management measures and emergency preparedness status are not explicitly indicated in the data, hinting at potential areas for improvement and future development in enhancing the dam's safety and resilience.
Water resource and climate enthusiasts will find Hi-Water an intriguing case study, highlighting the intersection of federal and state regulations in safeguarding water supply infrastructure. With its location in a picturesque natural setting in Wyoming, the dam serves as a vital component in the region's water management system, emphasizing the importance of proactive risk assessment and emergency planning for sustainable water resource management in the face of changing climate conditions.

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.
