Walker Creek dam
Walker Creek
Walker Creek, located in Marin County, California, is a crucial water resource managed by local government for irrigation purposes since 1976. This earth dam stands at a height of 25 feet and has a storage capacity of 66 acre-feet, serving the surrounding area with a drainage area of 0.39 square miles. The dam, situated on Tr Walker Creek, has a low hazard potential and is regularly inspected and maintained to ensure its structural integrity.
Despite its primary purpose for irrigation, Walker Creek also provides recreational opportunities for the community. The dam's satisfactory condition assessment in 2017 reflects the diligent efforts of the state regulatory agency and local government in ensuring the safety and functionality of the structure. With its proximity to Marshall and the San Francisco District, Walker Creek serves as a vital asset in water management and climate resilience efforts in the region.
As a key component of the state's water infrastructure, Walker Creek plays a significant role in water resource management and climate adaptation strategies. With its low hazard potential and satisfactory condition, the dam stands as a reliable source of water for irrigation and recreational activities, highlighting the importance of maintaining and monitoring such critical infrastructure in the face of changing climate conditions. Walker Creek exemplifies the collaborative efforts between local government and state agencies in safeguarding water resources for the benefit of the community and the environment.
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 Walker Creek
Where does the data for Walker Creek 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 Low 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.
