Jackson Creek Spillway dam
Jackson Creek Spillway
Jackson Creek Spillway, also known as Jackson Creek Dam, is a significant water resource structure located in Buena Vista, California. Operated by a Public Utility, this dam is crucial for water supply purposes and serves various other functions like Fish and Wildlife Pond, Hydroelectric, Recreation, and Water Supply. With a height of 37 feet and a storage capacity of 198,000 acre-feet, Jackson Creek Spillway plays a vital role in managing water resources in the region.
Managed by the Federal Energy Regulatory Commission, Jackson Creek Spillway has a high hazard potential and is subject to state regulations for safety. The dam, primarily made of earth with concrete elements, spans a length of 1360 feet and covers a surface area of 2200 acres. While it does not have a spillway, the dam is designed to withstand high water pressures and ensure the safety of the surrounding areas in case of emergencies.
Despite lacking recent condition assessments, Jackson Creek Spillway remains a critical infrastructure for water management in Amador County. With its high risk assessment rating and the absence of detailed risk management measures, ongoing monitoring and maintenance are essential to ensure the safety and efficiency of this important water resource structure.

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 Jackson Creek Spillway
Where does the data for Jackson Creek Spillway 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.
