Summary

Constructed in 1914, this structure stands at a height of 13 feet and has a hydraulic height of 11 feet, providing storage of up to 684 acre-feet of water. The dam spans a length of 1,221 feet and covers a surface area of 93 acres, serving as an offstream source for Sage Creek.

Despite being categorized as having a low hazard potential and fair condition assessment, Sage Creek dam is subject to state regulations and inspections, with enforcement and permitting conducted by the Wyoming State Engineers Office. With Liz Cheney as the Congressional Representative for the area, the dam's uncontrolled spillway and single outlet gate serve as critical components for managing water flow. Although the risk assessment indicates a moderate level of risk, the structure meets regulatory guidelines and is monitored for any necessary risk management measures.

Water resource and climate enthusiasts intrigued by the historical significance and operational details of dams will find Sage Creek to be a fascinating example of early 20th-century irrigation infrastructure in Wyoming. With its modest size and functional design, this dam represents a valuable resource for the surrounding agricultural community, highlighting the importance of sustainable water management practices in the region. As stakeholders continue to prioritize safety and efficiency in water resource management, Sage Creek serves as a noteworthy case study in the ongoing efforts to balance water supply needs with environmental stewardship.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
