Summary
Built in 1970, this earth dam stands at a height of 22 feet and serves multiple purposes including fire protection, stock, and a small fish pond. With a storage capacity of 68 acre-feet, it covers a surface area of 6 acres and has a spillway width of 50 feet.
Despite being regulated and inspected by the Wyoming State Engineer's Office, Mullen is classified as having a low hazard potential and poor condition assessment. Its last inspection in September 2016 revealed the need for improvements. With a moderate risk assessment level, there is a call for enhanced risk management measures to ensure the safety and functionality of this vital water structure.
The location of Mullen, near Liz Cheney's congressional district, highlights the importance of maintaining and upgrading water resources in the face of changing climate patterns. As enthusiasts in water resource and climate issues, it is crucial to advocate for the necessary investments and policies that will safeguard structures like Mullen and ensure a sustainable water future for Wyoming and beyond.

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.
