Folsom Right Wing dam
Folsom Right Wing
Folsom Right Wing is a crucial water resource structure located in Sacramento, California, along the American River. Owned and operated by the Bureau of Reclamation, this earth dam was completed in 1955 primarily for flood risk reduction. With a height of 145 feet and a storage capacity of 1,120,000 acre-feet, it plays a significant role in managing water resources in the region. The dam also serves multiple purposes including hydroelectric power generation, irrigation, recreation, and water supply.
The dam has a high hazard potential and a risk assessment rating of 2, indicating the importance of its maintenance and oversight. While the condition assessment is not available, regular inspections by the Bureau of Reclamation ensure its structural integrity and safety. Although the dam does not have a spillway, its design and operational protocols are carefully managed to mitigate any potential risks. Furthermore, the Emergency Action Plan (EAP) for Folsom Right Wing was last revised in January 2020, highlighting the commitment to preparedness for any emergency situations.
Overall, Folsom Right Wing stands as a crucial infrastructure for water management and flood control in the region. With its strategic location on the American River and its multi-purpose functionalities, it is a key asset for ensuring water supply reliability, flood protection, and environmental sustainability. The Bureau of Reclamation's continued oversight and management of this dam demonstrate a commitment to safeguarding the surrounding communities and water resources for future generations.
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 Folsom Right Wing
Where does the data for Folsom Right Wing 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.
