About this dam

Philbrook Main

Philbrook Main is a privately-owned dam located in Stirling City, California, along Philbrook Creek. Built in 1926, this Earth dam stands at a height of 87 feet and stretches 850 feet in length, with a storage capacity of 5009 acre-feet. The primary purpose of this structure is for hydroelectric power generation, making it an essential resource for renewable energy in the region.

Managed by the Federal Energy Regulatory Commission, Philbrook Main is subject to state regulation and inspection, ensuring its safety and compliance with dam standards. With a high hazard potential and a very high risk assessment, emergency preparedness measures are crucial for the surrounding area. Despite its age, the dam's condition assessment is not available, highlighting the need for continued monitoring and maintenance to mitigate potential risks.

Overall, Philbrook Main serves as a vital component of California's water resource infrastructure, providing both hydroelectric power and water storage benefits. As climate change impacts water resources, the proper management and upkeep of dams like Philbrook Main are crucial for ensuring a sustainable and resilient water supply for the region. Enthusiasts in water resources and climate change will find this dam's history, design, and operational details intriguing as they study the intersection of water management and environmental sustainability.

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.

FAQ

About Philbrook Main

Where does the data for Philbrook Main 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.
