Santa Rosa Creek Reservoir dam
Santa Rosa Creek Reservoir
Santa Rosa Creek Reservoir, also known as Spring Lake, is a local government-owned earth dam located in Santa Rosa, California. Completed in 1963, this reservoir serves multiple purposes including flood risk reduction, recreation, and water supply. With a height of 37 feet and a hydraulic height of 27.5 feet, it has a storage capacity of 3,550 acre-feet and covers a surface area of 154 acres.
Managed by the Natural Resources Conservation Service, Santa Rosa Creek Reservoir is regulated by the California Department of Water Resources for safety and inspection. The dam's hazard potential is categorized as high, but its condition assessment as of September 2017 was deemed satisfactory. The reservoir is situated on Santa Rosa Creek and has a drainage area of 0.55 square miles, highlighting its importance in managing water resources in the region.
Surrounded by picturesque landscapes and offering recreational opportunities such as fishing and boating, Santa Rosa Creek Reservoir is not only a vital infrastructure for flood control but also a popular spot for outdoor enthusiasts. Its strategic location in Sonoma County, coupled with its significant role in water supply management, makes it a noteworthy site for those interested in sustainable water resource 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 Santa Rosa Creek Reservoir
Where does the data for Santa Rosa Creek 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 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.
