Summary

1 is a privately owned earth dam located in Sheridan, Wyoming, along Baker Creek. Completed in 1981, this dam serves primarily for irrigation purposes, with a storage capacity of 39 acre-feet and a surface area of 5 acres. With a maximum discharge of 426 cubic feet per second, the dam stands at 25 feet high and has a spillway width of 40 feet for uncontrolled releases.

Despite being categorized with a low hazard potential and fair condition assessment, Fletcher No. 1 is regulated by the Wyoming State Engineer's Office and undergoes regular inspections. The dam, designed by Elmer Kuball, is situated in a picturesque setting with a drainage area of 1.8 square miles. Its risk assessment is deemed moderate, highlighting the importance of ongoing risk management measures to ensure the safety and integrity of the structure for the surrounding community and environment.

As a key feature in the local water resource infrastructure, Fletcher No. 1 plays a vital role in supporting agricultural activities and maintaining ecological balance in the area. With Liz Cheney as the Congressional Representative for the region, the dam stands as a testament to the careful planning and construction that went into meeting the water needs of the community while prioritizing safety and sustainability for future generations of water resource and climate enthusiasts in Wyoming.

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.
