Cloak Lake dam
Cloak Lake
Cloak Lake, located in Grenada, California, is a privately owned water supply reservoir regulated and inspected by the Department of Water Resources and the Safety of Dams agency. The dam, constructed in 1955, stands at 13 feet tall and has a storage capacity of 123 acre-feet. With a primary purpose of water supply for irrigation and domestic use, Cloak Lake plays a vital role in providing water resources to the surrounding area.
Despite its satisfactory condition assessment, Cloak Lake has been classified as having a significant hazard potential, indicating the importance of regular inspections and maintenance to ensure the safety of the structure. The last inspection, conducted in February 2020, highlighted the need for ongoing monitoring and risk management measures to mitigate any potential threats. With its location on the Tr Shasta River and close proximity to Siskiyou, California, Cloak Lake serves as a critical water source for the region and underscores the importance of sustainable water resource management in the face of changing climate conditions.
As a key component of the water infrastructure in the area, Cloak Lake represents the intersection of human ingenuity and natural resources. With ongoing regulatory oversight and a focus on maintaining its integrity, this earth dam continues to play a vital role in supporting agriculture and water supply needs in the region. For water resource and climate enthusiasts, Cloak Lake serves as a fascinating case study in the importance of balancing human needs with environmental stewardship in the face of a changing climate landscape.
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 Cloak Lake
Where does the data for Cloak 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 Significant 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.
