Jeff Davis dam
Jeff Davis
Jeff Davis is a public utility dam located in Glencoe, California, serving as a vital water supply source for irrigation and general water supply purposes. Built in 1973, this earth dam stands at a height of 114 feet, with a hydraulic height of 109 feet, and a storage capacity of 2059 acre-feet. Situated on Tr Wet Gulch Creek, Jeff Davis Dam plays a crucial role in water management in Calaveras County, California.
Managed by the Department of Water Resources (DWR) and regulated for safety by the Safety of Dams agency, Jeff Davis Dam has a high hazard potential but is currently assessed as satisfactory in condition. The dam spans 102 feet in length, covering a surface area of 62 acres and draining a 0.4 square mile area. Despite its age, Jeff Davis Dam continues to fulfill its primary purpose of providing water to the surrounding areas, with regular inspections conducted to ensure its operational integrity.
Representing a significant piece of water infrastructure in the region, Jeff Davis Dam is closely monitored for any potential risks or hazards. With its emergency action plan regularly updated and inspections conducted at a frequency of one year, the dam remains a critical component of water resource management in the area. As climate change impacts water availability, the importance of structures like Jeff Davis Dam in ensuring water security for communities becomes increasingly evident.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Jeff Davis
Where does the data for Jeff Davis 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.
