Denmark Wash dam
Denmark Wash
Denmark Wash, a federally-owned structure located in Sevier, Utah, serves as a crucial flood risk reduction measure along the tributary to the Sevier River. Completed in 1935, this earth dam stands at a structural height of 11 feet and a hydraulic height of 6 feet, with a dam length of 900 feet. With a storage capacity of 50 acre-feet, it plays a vital role in managing water flow and mitigating potential flooding in the surrounding areas.
Managed by the Utah Division of Water Rights, Denmark Wash is subject to state regulation, inspection, and enforcement to ensure its functionality and safety. Despite being classified as having a low hazard potential, the structure has not been assessed for its current condition. Its last inspection in May 2016 revealed no significant issues, and the dam is deemed to meet regulatory guidelines. With its primary purpose being flood risk reduction, Denmark Wash continues to play a crucial role in protecting the local community from potential water-related disasters.
Located in the city of Aurora, Denmark Wash is situated within the Los Angeles District and falls under the jurisdiction of Congressman Chris Stewart. With a drainage area of 25 square miles, this earth dam serves as a vital piece of infrastructure for water resource management in the region. As a key component of the water network in Sevier County, Denmark Wash stands as a testament to the importance of effective water resource management in mitigating the impacts of climate change and ensuring the safety and well-being of local communities.

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 Denmark Wash
Where does the data for Denmark Wash 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.
