Summary
Built in 1953, this earth dam stands at 25 feet high and 400 feet long, with a storage capacity of 161 acre-feet. The primary purpose of Fields is for irrigation, although it also serves fire protection, stock, and small fish pond needs. The dam is regulated by the State of Wyoming and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating.
Although Fields has not been rated for its condition, it is equipped with a slide (sluice gate) outlet gate and an uncontrolled spillway with a width of 50 feet. The dam is in Congressional District 00 of Wyoming, represented by Liz Cheney (R), and falls under the jurisdiction of the US Army Corps of Engineers Omaha District. Despite its low hazard potential, Fields presents a moderate risk due to its location and characteristics, emphasizing the importance of ongoing monitoring and management to ensure its safety and functionality for irrigation and other purposes in the region.

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.
