About this dam

Lower Sardine Lake

Lower Sardine Lake, located in Sierra City, California, is a state-regulated water supply reservoir completed in 1965 with a primary purpose of providing water for various uses. The dam, standing at a height of 17 feet with a hydraulic height of 9 feet, holds a storage capacity of 280 acre-feet and covers a surface area of 38 acres. The reservoir is fed by Sardine Creek and serves as a critical resource for both recreation and water supply in the region.

With its low hazard potential and satisfactory condition assessment, Lower Sardine Lake offers a safe and reliable water source for the surrounding community. The dam is under the jurisdiction of the California Department of Water Resources and is subject to regular inspections, permitting, and enforcement to ensure its structural integrity and operational effectiveness. Despite its modest size, the reservoir plays a significant role in managing water resources and supporting the ecological balance of the area.

For water resource and climate enthusiasts, Lower Sardine Lake presents a fascinating case study of sustainable water management in California. As a vital piece of infrastructure in the region, the reservoir exemplifies the careful balance between water supply needs, recreational opportunities, and environmental stewardship. Its role in providing essential services while maintaining a low-risk profile underscores the importance of responsible dam construction and operation in mitigating the impacts of climate change on water resources.

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 Lower Sardine Lake

Where does the data for Lower Sardine Lake 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.
