Sargent No 1 dam
Sargent No 1
Sargent No 1 is a privately owned irrigation dam located in Coalville, Utah, along the Elkhorn Ditch. Constructed in 1956 by the USDA NRCS, this earth dam stands at a hydraulic height of 31 feet and a structural height of 36 feet, with a length of 600 feet. It serves the primary purpose of irrigation, storing 120 acre-feet of water with a normal storage capacity of 90 acre-feet. Despite its low hazard potential, the dam is regulated by the Utah Division of Water Rights and undergoes state inspection, enforcement, and permitting.
The dam's location in Summit County, Utah, makes it a vital resource for water management in the region, with a drainage area of 0.3 square miles and a maximum discharge of 5 cubic feet per second. While the dam's condition assessment is currently not rated, it has a regular inspection frequency of every 5 years, with the last inspection conducted in July 2016. Sargent No 1's emergency action plan status, risk assessment, and management measures are not fully documented, but its low hazard potential suggests a relatively low level of risk associated with the structure.
Overall, Sargent No 1 plays a crucial role in supporting agricultural activities in the area through irrigation water storage. Its design by the USDA NRCS and regulation by the Utah Division of Water Rights ensure that it meets safety standards and operational requirements. With its modest scale and low hazard potential, the dam serves as a significant yet manageable component of the local water resource infrastructure, contributing to the sustainable management of water in the region.

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.

About Sargent No 1
Where does the data for Sargent No 1 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 Low 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.
