Summary
This Earth-type structure stands at a height of 25 feet, with a hydraulic height of 22 feet and a structural height of 25 feet. It spans 315 feet in length and has a storage capacity of 38 acre-feet, providing essential water resources for the area. The dam is regulated and inspected by the State of Wyoming, ensuring its safety and compliance with state standards.
The dam's spillway, with a width of 33 feet, is uncontrolled, and the hazard potential is rated as low, with a moderate risk assessment score of 3. Despite its importance for water resource management, the condition assessment of Gates is marked as poor, indicating a need for maintenance and potential improvements to enhance its longevity and functionality. The last inspection was conducted in August 2017, with an inspection frequency of 5 years, highlighting the ongoing monitoring and management of this crucial water infrastructure.
While Gates serves as a vital resource for the surrounding area, its condition and risk assessment underscore the importance of continued oversight and maintenance to ensure its continued effectiveness. With its location on the South Fork Prairie Dog Creek, the dam plays a significant role in water supply and protection, emphasizing the need for proactive management and potential upgrades to address any identified deficiencies. As climate change impacts water resources, the proper regulation and maintenance of dams like Gates become increasingly critical for long-term water security and sustainability.

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.
