Thurman dam
Thurman
Thurman is a privately owned dam located in Millville, California, along the Slaughter Pole Creek. Built in 1966, this Earth-type dam stands at a height of 62.5 feet and serves primarily as a water supply source, with a storage capacity of 140 acre-feet. The dam also supports irrigation and recreational activities in the area. Despite its low hazard potential, Thurman is regulated by the California Department of Water Resources (DWR) for safety and is subject to regular inspections and enforcement measures to ensure its satisfactory condition.
Situated in Shasta County, Thurman plays a vital role in water management within its 0.44 square mile drainage area. The dam's structure spans 350 feet in length and covers a surface area of 13 acres. With its location in a region prone to climate variability, Thurman serves as a critical infrastructure for maintaining water security and supporting agricultural activities in the surrounding area. The dam's compliance with state regulations and its satisfactory condition underscore its importance in safeguarding water resources and mitigating potential risks associated with dam failures.
Managed by private owners, Thurman's location in the San Francisco District underscores its significance in regional water supply infrastructure. As climate change continues to impact water availability and quality, dams like Thurman play a crucial role in ensuring sustainable water management practices. The dam's low hazard potential, coupled with regular inspections and enforcement measures, highlights its commitment to maintaining water security and resilience in the face of evolving climate challenges.

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 Thurman
Where does the data for Thurman 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.
