Summary
1, located in Converse County, Wyoming, is a state-owned Fish and Wildlife Pond that was completed in 1954. The dam, primarily made of earth with stone core types and soil foundations, stands at a height of 28 feet and spans a length of 1155 feet. The reservoir has a normal storage capacity of 100 acre-feet and serves as a vital habitat for aquatic life in the area.
Sitting on Six Mile Creek, the dam, managed by the State of Wyoming, is regulated, permitted, inspected, and enforced by the state regulatory agency (SEO). With a spillway width of 192 feet and a maximum discharge capacity of 3466 cubic feet per second, the dam has a significant hazard potential and an unsatisfactory condition assessment as of its last inspection in June 2018. Despite these challenges, the reservoir provides essential recreational opportunities and water resources for the local community.
As climate change continues to impact water resources and ecosystems, the management and maintenance of dams like Douglas Fishing Lake No. 1 become increasingly crucial. With a moderate risk assessment rating, there is a need for ongoing monitoring, risk management measures, and emergency preparedness to ensure the safety and sustainability of this important water infrastructure in Wyoming.

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.
