Summary

1 is a private irrigation dam located in Millard County, Utah, completed in 1948. Managed by the Utah Division of Water Rights, this earth dam stands at a hydraulic height of 18 feet and a structural height of 24 feet, providing irrigation water storage of 17,781 acre-feet from the Fool Creek watershed. With a drainage area of 45.1 square miles, the dam plays a crucial role in water management for agricultural purposes in the region.

Despite its age, Fool Creek No. 1 remains in a condition that has not been rated, with significant hazard potential. Regular inspections are carried out every two years, with the last inspection conducted in May 2020. The dam has not been modified over the years, and it lacks emergency action plans, inundation maps, and risk assessment protocols. As a vital piece of infrastructure for water resource management in the area, it is essential to address any potential risks and ensure the dam's continued safe operation to meet the irrigation needs of the surrounding agricultural community.

Located in the Sacramento District, Fool Creek No. 1 underscores the importance of maintaining and monitoring aging dams for both water resource sustainability and public safety. As climate change impacts water availability and distribution, the proper management of dams like Fool Creek No. 1 becomes increasingly critical in ensuring a reliable water supply for agricultural activities and mitigating potential hazards associated with aging infrastructure. Collaborative efforts between private owners, state agencies, and regulators are essential to address any identified risks and implement necessary measures to safeguard the dam's integrity and functionality for the future.

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.
