Summary

Built in 2002, this dam stands at 28 feet high and has a hydraulic height of 23 feet, with a structural height of 34 feet. It has a storage capacity of 49 acre-feet and a normal storage level of 30 acre-feet, covering a surface area of 3.38 acres.

The dam, situated on an unnamed draw, is regulated by the State of Wyoming and is inspected and enforced by the State Regulatory Agency. With a low hazard potential and fair condition assessment as of August 2017, T55nr75w23swne has a moderate risk assessment rating of 3. The dam has a spillway width of 10 feet and an uncontrolled spillway type, with a maximum discharge capacity of 690 cubic feet per second. Overall, this dam plays a crucial role in water resource management and wildlife conservation in the region.

Despite its relatively low hazard potential, the dam at T55nr75w23swne remains an essential asset for fire protection and water supply in the area. With its strategic location on County Road and its multiple purposes including serving as a fish and wildlife pond, this earth dam contributes to the overall water infrastructure in Wyoming. As climate change continues to impact water resources, the proper maintenance and regulation of dams like T55nr75w23swne become increasingly important for sustainable water management and environmental protection in the region.

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.
