Summary

Completed in 2012, this earth dam stands at a structural height of 65 feet and has a hydraulic height of 60 feet, providing a maximum storage capacity of 1843 acre-feet. The reservoir, regulated by the Utah Division of Water Rights, plays a crucial role in managing water resources in the region.

With a high hazard potential and a satisfactory condition assessment, Adobe Wash Regulating Reservoir has undergone regular inspections and enforcement by the state regulatory agency. The reservoir has a maximum discharge capacity of 299 cubic feet per second and a spillway width of 60 feet. Despite not having associated structures or locks, the reservoir serves as a vital component in the water infrastructure of the area, contributing to the irrigation needs of the community.

As a significant water resource in the region, Adobe Wash Regulating Reservoir demonstrates a commitment to water management and conservation. Through state permitting, inspection, and enforcement, this reservoir ensures the safe and efficient storage of water for irrigation purposes. With its strategic location and design, Adobe Wash Regulating Reservoir stands as a testament to the importance of sustainable water practices in the face of changing climatic conditions.

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.
