Hat Creek No. 2 Diversion dam
Hat Creek No. 2 Diversion
Hat Creek No. 2 Diversion is a privately owned hydroelectric facility located in Big Bend, California, along the Hat Creek river. The dam, completed in 1943, stands at 29 feet high and has a storage capacity of 629 acre-feet. With a controlled spillway and a maximum discharge of 1490 cubic feet per second, this concrete gravity dam plays a vital role in water resource management in the region.
Managed by the Federal Energy Regulatory Commission, Hat Creek No. 2 Diversion is subject to state regulation and inspection, ensuring its safety and compliance with environmental standards. Despite its low hazard potential, the risk assessment for this structure is classified as very high, highlighting the importance of effective risk management measures. The Emergency Action Plan for the dam was last revised in October 2020, indicating a commitment to preparedness and safety.
For water resource and climate enthusiasts, Hat Creek No. 2 Diversion serves as a fascinating example of sustainable energy generation and water storage in California. Its role in providing hydroelectric power and regulating water flow in the Hat Creek river underscores the importance of responsible infrastructure management in the face of changing climate conditions and increasing water demands.
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 Hat Creek No. 2 Diversion
Where does the data for Hat Creek No. 2 Diversion 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.
