Summary

Built in 1961, this earth dam stands at a height of 25 feet and has a storage capacity of 124 acre-feet. The primary purpose of the dam is for irrigation, serving the surrounding area with water from Pinto Creek.

Despite its age, Pinto Dam is considered to have a low hazard potential, but its condition has been assessed as poor. The last inspection in August 2021 revealed the need for improvement, emphasizing the importance of regular maintenance and upkeep. With a moderate risk assessment rating of 3, there is a potential for increased risk if necessary risk management measures are not implemented.

Situated in the Omaha District within Congressional District 00 in Wyoming, Pinto Dam plays a crucial role in water resource management in the region. With its uncontrolled spillway and one slide gate for outlet control, the dam provides vital irrigation water while posing manageable risks that must be addressed to ensure its continued functionality and safety for the community.

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.
