Summary

Constructed in 1957, this earth dam stands at a structural height of 29 feet with a hydraulic height of 23 feet. The reservoir has a storage capacity of 1230 acre-feet, providing essential water for agricultural purposes in the region. Managed by a private entity, the dam is regulated by the Utah Division of Water Rights, ensuring proper inspection, enforcement, and permitting processes are in place to maintain its functionality.

With a drainage area of 2.7 square miles and a maximum discharge of 63 cubic feet per second, Whiterocks Lake plays a vital role in water resource management for the surrounding community. The dam's hazard potential is classified as high, highlighting the importance of regular inspections and maintenance to uphold its structural integrity. Despite the potential risks, the dam's condition assessment remains satisfactory, ensuring its continued operation for irrigation purposes.

As a key feature along the Whiterocks River, this earth dam not only supports agricultural activities but also contributes to the broader water infrastructure of the region. Its strategic location and storage capacity make Whiterocks Lake a significant asset in water resource management and climate resilience efforts in Uintah, Utah. With proper oversight and maintenance, this reservoir will continue to play a crucial role in sustaining water supplies for the local 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.
