Summary

Managed by the USDA NRCS, this structure serves primarily for irrigation purposes and was completed in 1918. With a hydraulic height of 40 feet and a structural height of 45 feet, Oak Creek has a storage capacity of 1000 acre-feet, with a normal storage level of 915 acre-feet.

Situated in the city of Hanksville, Oak Creek spans a length of 457 feet and has a drainage area of 2.5 square miles. The dam has a high hazard potential and is classified as being in fair condition. The Utah Division of Water Rights regulates and inspects Oak Creek, ensuring its safe operation and compliance with state regulations. With a maximum discharge capacity of 68 cubic feet per second, Oak Creek plays a crucial role in providing water for agricultural activities in the region.

Despite its age, Oak Creek continues to be a vital water resource for the community, contributing to the sustainability of local agriculture. With its long history and significant storage capacity, Oak Creek stands as a testament to the importance of water management in the face of changing climate conditions. Enthusiasts of water resources and climate will find Oak Creek to be a fascinating example of how infrastructure can adapt and endure over the years to meet the needs of its users.

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.
