Upper Plaskett dam
Upper Plaskett
Upper Plaskett is a federal-owned dam located in Glenn, California, with a primary purpose of recreation. Built in 1955, this earth dam stands at a height of 28 feet and has a length of 210 feet, impounding Plaskett Creek. Managed by the Forest Service, Upper Plaskett offers a serene escape for water resource and climate enthusiasts, with its low hazard potential and moderate risk assessment rating.
Despite being unregulated by the state, Upper Plaskett is subject to regular inspections by the Forest Service, with the last one conducted in June 2014. While the dam's condition is currently not rated, its emergency action plan status and risk management measures remain unspecified. Situated in the Sacramento District and overseen by federal agencies, Upper Plaskett provides a vital recreational resource while maintaining a cautious approach towards risk and safety.
With its scenic location and historical significance, Upper Plaskett serves as a testament to responsible stewardship of water resources in California. As climate change continues to impact the region, the importance of maintaining and managing dams like Upper Plaskett for both recreational and environmental purposes becomes increasingly evident. Enthusiasts of water resources and climate alike can appreciate the delicate balance of preservation and utilization that Upper Plaskett represents in the face of evolving environmental challenges.
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 Upper Plaskett
Where does the data for Upper Plaskett 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.
