Summary
Built in 1973 by the USDA NRCS, this earth dam stands at a hydraulic height of 19 feet and a structural height of 24 feet, with a length of 520 feet. The reservoir has a storage capacity of 435 acre-feet and serves as a vital water resource for the surrounding agricultural community.
Managed by the Utah Division of Water Rights, Deep Lake is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. The dam is situated on Cottonwood Creek, contributing to a drainage area of 0.2 square miles. Although the condition assessment is not rated, the hazard potential is considered significant, prompting regular inspections every two years to mitigate risks and ensure the reservoir's integrity for irrigation purposes.
Deep Lake (Sevier) plays a crucial role in sustaining agricultural activities in the region, with a normal storage capacity of 285 acre-feet. The dam's location in the city of Annabella, Utah, and its association with the Natural Resources Conservation Service highlight its importance as a key water management infrastructure in the area. Climate and water resource enthusiasts would find interest in the reservoir's construction details, regulatory oversight, and its impact on the local ecosystem and economy.

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.
