Summary
Managed by the Utah Division of Water Rights, this dam serves the primary purpose of irrigation along the Santa Clara River. Completed in 1970, Gunlock stands at a structural height of 117 feet and has a hydraulic height of 103 feet, with a storage capacity of 15,041 acre-feet. Its location in Washington County makes it a vital asset for water management in the region.
With a high hazard potential, Gunlock dam is subject to regular inspections and enforcement by state regulators to ensure its safe operation. The last inspection in October 2020 deemed its condition as satisfactory, highlighting the importance of ongoing maintenance and risk management measures. Despite its age, Gunlock continues to play a crucial role in providing water for irrigation and other purposes in the area, showcasing the resilience of water infrastructure in the face of changing climatic conditions.
As climate enthusiasts and water resource advocates, the data on Gunlock dam serves as a reminder of the vital role that such structures play in ensuring water security and sustainable resource management. By understanding the details of its design, storage capacity, and regulatory oversight, we can appreciate the complex interplay between human engineering and natural forces in safeguarding our water supply. Gunlock stands as a testament to the ongoing efforts to balance water needs with environmental considerations, making it a fascinating subject for further study and appreciation.

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.
