Miller Flat dam
Miller Flat
Miller Flat is a private irrigation dam located in Emery, Utah, along the Miller Flat Creek. This earth dam was completed in 1949 and stands at a height of 73 feet, with a hydraulic height of 68 feet. It serves the primary purpose of irrigation, providing a storage capacity of 6,393 acre-feet and a normal storage of 5,560 acre-feet. The dam has a drainage area of 9 square miles and a maximum discharge capacity of 280 cubic feet per second.
Managed by the Utah Division of Water Rights, Miller Flat dam is considered to have a high hazard potential but is currently in satisfactory condition. It undergoes regular inspections, with the last one conducted in July 2020. The dam is regulated, permitted, and inspected by the state agency, ensuring its safety and compliance with regulations. This crucial infrastructure plays a vital role in supporting agricultural activities in the region, highlighting the intersection of water resources and climate management in sustaining local communities.
With its picturesque location in the Huntington city area and its vital role in providing irrigation water, Miller Flat dam stands as a testament to the importance of water resource management in the face of changing climate conditions. The dam's history, design, and operational characteristics make it a fascinating subject for water resource and climate enthusiasts interested in understanding the complexities of water infrastructure and its impact on local ecosystems and 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 Miller Flat
Where does the data for Miller Flat 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.
