Leigh Hill Reservoir dam
Leigh Hill Reservoir
Located in Cedar City, Utah, Leigh Hill Reservoir is a privately owned water storage facility primarily used for irrigation purposes. Managed by the Utah Division of Water Rights, this reservoir was completed in 2008 and has a storage capacity of 142 acre-feet, with a normal storage level of 111 acre-feet. With a hazard potential classified as high but a satisfactory condition assessment, the reservoir plays a crucial role in supporting agricultural activities in the region.
Situated in Iron County, Leigh Hill Reservoir has a hydraulic height of 29 feet and a structural height of 32 feet. The dam is of earth type construction, serving as a vital water resource for the surrounding area. The reservoir's maximum discharge capacity is 6.7 cubic feet per second, ensuring a reliable supply of water for irrigation needs. Despite its high hazard potential, the reservoir's condition remains satisfactory, ensuring its continued functionality for the local community.
With its strategic location and importance for irrigation, Leigh Hill Reservoir stands as a key water resource in the region. Its completion in 2008 marked a milestone in water management in Cedar City, providing a reliable source of water for agricultural activities. As a regulated facility under the Utah Division of Water Rights, the reservoir undergoes regular inspections and enforcement measures to ensure its safe operation and contribution to the local economy.

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.
- 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.
- 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.
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, environmental 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.
Plan around the weather

About Leigh Hill Reservoir
Where does the data for Leigh Hill Reservoir come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
