Shaver Dike dam
Shaver Dike
Shaver Dike, located in Shaver Lake, California, is a private structure primarily used for hydroelectric purposes. Built in 1982, this concrete dam stands at a height of 8 feet and has a total length of 409 feet. With a storage capacity of 135,568 acre-feet and serving as a multipurpose reservoir, Shaver Dike not only generates hydroelectric power but also provides recreational opportunities for visitors.
Managed by the Federal Energy Regulatory Commission, Shaver Dike is subject to state regulations and inspections to ensure its safety and compliance with environmental standards. Despite being classified as having a high hazard potential, the dam's condition assessment remains unavailable, highlighting the need for ongoing risk management measures. In case of emergencies, an Emergency Action Plan is in place, with the last revision dated in December 2020 to meet safety guidelines and ensure preparedness in the event of a crisis.
Overall, Shaver Dike represents a vital infrastructure for water resource management and energy production in the region, showcasing the intersection of engineering innovation and environmental stewardship. As a key component of the Stevenson Creek watershed, this concrete dam plays a crucial role in sustaining water supply, supporting wildlife habitats, and enhancing the recreational experience for residents and visitors alike. With its strategic location and operational efficiency, Shaver Dike continues to be a cornerstone of sustainable development in the area, serving as a model for responsible water resource management in a changing climate.
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 Shaver Dike
Where does the data for Shaver Dike 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 High 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.
