Volo Mining Company dam
Volo Mining Company
The Volo Mining Company, located in Folsom, California, operates a privately owned dam on Indian Creek, completed in 1958 for flood risk reduction and water supply purposes. This earth dam stands at a height of 35 feet with a hydraulic height of 26.2 feet, providing a storage capacity of 148 acre-feet. The dam is under state regulation by the California Department of Water Resources and Safety of Dams, ensuring regular inspections, permitting, and enforcement measures are in place.
With a hazard potential categorized as high, the Volo Mining Company dam has been assessed as satisfactory in condition as of September 2017. The last inspection in January 2021 indicated a frequency of every one year for assessments. The dam's location in El Dorado County, within the San Francisco District, underscores its importance in managing water resources and mitigating flood risks for the local community. As a key infrastructure in the region, the dam plays a crucial role in safeguarding against potential inundation events and ensuring the safety of downstream areas.
Despite the lack of associated structures or modifications over the years, the Volo Mining Company dam remains a vital asset in water resource management. The involvement of state regulatory agencies, along with the satisfactory condition assessment, underscores the commitment to maintaining the dam's integrity and functionality. As climate change continues to impact water resources and weather patterns, the Volo Mining Company dam serves as a critical infrastructure for flood protection and water supply reliability 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 Volo Mining Company
Where does the data for Volo Mining Company 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.
