Catfish Reservoir Report
Nearby: Hillside Pond Spearhead Pond #1
Last Updated: March 4, 2026
Catfish is a privately owned dam located in Converse, Wyoming, on the Fly Draw River.
Summary
Built in 1977 by designer Daniel A. Siek, this earth dam stands at 30 feet high with a hydraulic height of 26 feet and a length of 330 feet. The primary purpose of Catfish is for fire protection, stock, and as a small fish pond, with a storage capacity of 80 acre-feet and a drainage area of 1.5 square miles.
Despite its low hazard potential, Catfish is in poor condition as of its last inspection in June 2017. With a moderate risk assessment rating, the dam is in need of maintenance and potential risk management measures. The dam features an uncontrolled spillway with a width of 25 feet, and a maximum discharge capacity of 425 cubic feet per second.
Located on an unnamed ranch in Converse County, Catfish serves as a vital resource for water storage and wildlife habitat in the region. Enthusiasts of water resources and climate will find Catfish a fascinating structure with a unique blend of functions, serving both practical and ecological purposes in the surrounding area.

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.
