Lake Suzanne dam
Lake Suzanne
Lake Suzanne, located in Montague, California, is a private recreational lake managed by the USDA NRCS. Built in 1962, this earth dam structure stands at 18 feet high and spans 1966 feet in length, with a storage capacity of 169 acre-feet. The primary purposes of Lake Suzanne include flood risk reduction, irrigation, and recreation, making it a valuable resource for the local community.
With a surface area of 17 acres and a drainage area of 1.7 square miles, Lake Suzanne is fed by the Tr- Shasta River and has a maximum discharge capacity of 1300 cubic feet per second. Despite its low hazard potential, the condition assessment of the dam is currently not available, indicating a need for further inspection and maintenance. While the emergency action plan status is also unknown, the recreational opportunities and environmental benefits provided by Lake Suzanne make it an important water resource for both residents and visitors in the Siskiyou County area.
Overall, Lake Suzanne serves as a vital recreational and water management asset in California, offering opportunities for outdoor activities and contributing to flood risk reduction and irrigation needs in the region. As a privately owned facility, it remains under the management of the USDA NRCS, ensuring its continued operation and maintenance for the benefit of the community. Further assessments and monitoring may be needed to ensure the long-term safety and effectiveness of this important water resource.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Lake Suzanne
Where does the data for Lake Suzanne 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.
