Tremaine Reservoir dam
Tremaine Reservoir
Tremaine Reservoir, also known as Hay Lake, is a Federal-owned water storage structure located in Coconino County, Arizona. Built in 1952 by the USDA Natural Resource Conservation Service, the primary purpose of the reservoir is irrigation, with additional benefits for fire protection, stock watering, and fish and wildlife habitat. The dam is an earth type structure with a height of 30 feet and a length of 1935 feet, providing a storage capacity of 8000 acre-feet and a surface area of 265 acres.
Situated on the Jacks Canyon Tributary in the Two Guns area, Tremaine Reservoir plays a crucial role in water resource management and conservation efforts in the region. With a low hazard potential and fair condition assessment as of August 2020, the reservoir is maintained and regulated by the Forest Service to ensure safe operations. The risk assessment for the dam is categorized as moderate, indicating the need for ongoing monitoring and risk management measures to protect the surrounding communities and environment.
Despite its relatively small drainage area of 17 square miles, Tremaine Reservoir has a maximum discharge capacity of 7647 cubic feet per second, with an uncontrolled spillway width of 231 feet. Regular inspections every 10 years help to assess the structural integrity and safety of the dam, with the last assessment conducted in August 2020. As a valuable resource for irrigation and conservation in the region, Tremaine Reservoir continues to play a vital role in water management and climate resilience efforts.
Dam data reference
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 Tremaine Reservoir
Where does the data for Tremaine Reservoir 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.
