Summary
The dam, designed by Adam Bedard of Applied Hydrology Associates, stands at 22 feet high with a hydraulic height of 19 feet and a structural height of 28 feet. It has a storage capacity of 39 acre-feet and covers a surface area of 3.55 acres, serving as a vital resource for fish and wildlife in the area.
With a low hazard potential and fair condition assessment as of August 2017, T55nr75w22nwne is regulated by the State of Wyoming with inspection, enforcement, and permitting conducted by the SEO and DEQ. The dam spans 574 feet in length and has an uncontrolled spillway with a width of 10 feet. In the event of an emergency, the dam is equipped with a single valve outlet gate for water release. The risk assessment for T55nr75w22nwne is moderate, indicating a need for ongoing monitoring and management measures to ensure the safety and integrity of the structure.
Overall, T55nr75w22nwne plays a crucial role in maintaining water resources in the region, providing essential fire protection, livestock water supply, and habitat for small fish and wildlife. With its strategic location along an unnamed draw in Campbell County, this dam represents a balanced approach to water management, supporting both human and ecological needs while adhering to state regulatory standards for dam safety and operation.

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.
