Shingle Mill dam
Shingle Mill
Shingle Mill is a state-regulated water resource structure located in Mayfield, Utah, along the Mid South Fork Twelvemile Creek. Managed by the Utah Division of Water Rights, this dam is classified as an Earth dam with a significant hazard potential. Despite lacking specific details on its physical dimensions and storage capacity, Shingle Mill is subject to regular inspections, enforcing state regulations and permitting requirements to ensure its safety and functionality.
The dam's condition assessment is currently marked as "Not Rated," indicating a need for further evaluation. The last inspection took place in July 2020, with an inspection frequency of every two years. With its proximity to Sanpete County and a history of state jurisdiction and enforcement, Shingle Mill serves as a critical infrastructure for water resource management in the region. Its emergency action plan status and risk assessment measures are currently unspecified, suggesting a potential area for improvement and preparedness in the face of climate challenges.
As a key component of the water infrastructure in Utah, Shingle Mill presents an intriguing case study for water resource and climate enthusiasts. Its location, state ownership, and regulatory oversight by the Utah Division of Water Rights highlight the importance of maintaining and monitoring such structures in the face of changing environmental conditions. Further research and assessment of Shingle Mill's operational capacity and risk management strategies could provide valuable insights for sustainable water resource management 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 Shingle Mill
Where does the data for Shingle Mill 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 Significant 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.
