Coon Camp dam
Coon Camp
Coon Camp is a privately owned dam located in Lassen, California, specifically near the Swickard Ranch house. This earth dam, completed in 1900, stands at a height of 23 feet and serves primarily for water supply purposes, including irrigation. It holds a storage capacity of 548 acre-feet and covers a surface area of 79 acres, drawing water from the Tr Horse Lake river or stream.
Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Coon Camp has been classified as a low hazard potential structure with a satisfactory condition assessment as of September 2017. Despite its age, regular inspections are conducted, with the last one taking place in October 2019. The dam is designed to handle normal discharges and is equipped with necessary safety features, although specific spillway details are not provided in the data. The surrounding area is deemed to be at a low risk, with no emergency action plan (EAP) currently in place.
Coon Camp serves as a vital water resource infrastructure in the region, ensuring a stable water supply for agricultural and domestic needs. Its historical significance and ongoing maintenance efforts underscore the importance of managing such structures to safeguard water resources and mitigate potential risks associated with aging infrastructure. For water resource and climate enthusiasts, Coon Camp represents a piece of California's water management history, intertwining engineering ingenuity with environmental stewardship for a sustainable future.

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 Coon Camp
Where does the data for Coon Camp 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.
