Warner Draw dam
Warner Draw
Warner Draw is a private water resource in Washington, Utah, designed by USDA NRCS and regulated by the Utah Division of Water Rights. Completed in 1975 for flood risk reduction, this earth dam stands at a hydraulic height of 51 feet and a structural height of 67 feet, with a length of 630 feet. With a storage capacity of 2300 acre-feet and a drainage area of 4.4 square miles, Warner Draw plays a crucial role in managing water levels and mitigating flood risks in the region.
Situated in a critical location that drains into the Virgin River, Warner Draw has a high hazard potential but is currently in satisfactory condition. The dam undergoes inspections every two years, with the last assessment conducted in November 2020. While emergency action plans and risk assessments are not specified in the data, the structure meets regulatory guidelines and serves as a vital infrastructure for water resource management in the area. With its strategic design and operational efficiency, Warner Draw stands as a testament to effective flood risk reduction measures in the region.
Managed by the Natural Resources Conservation Service, Warner Draw is a key component of water resource infrastructure in Utah. With a focus on flood risk reduction, this earth dam provides essential storage capacity and drainage area coverage to safeguard against potential inundation events. As a privately owned structure with state jurisdiction and regulatory oversight, Warner Draw exemplifies the collaborative efforts between government agencies and private entities in ensuring the resilience of water resources in the face of climate challenges.

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 Warner Draw
Where does the data for Warner Draw 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.
