Cloverswale dam
Cloverswale
Cloverswale is a privately owned dam located in Canby, California, specifically on Tr Witcher Creek. Built in 1973, this earth-type dam stands at a height of 21 feet and has a hydraulic height of 16.5 feet. With a storage capacity of 4620 acre-feet, Cloverswale primarily serves the purpose of water supply for irrigation and other uses in the area. The dam has a low hazard potential and has been assessed to be in satisfactory condition as of September 2017.
Managed by the California Department of Water Resources (DWR) under the Safety of Dams program, Cloverswale is regulated, permitted, inspected, and enforced by the state authorities. The dam has a drainage area of 4.7 square miles and a surface area of 462 acres. While no spillway information is provided, the dam has a length of 490 feet and is situated within Modoc County, California. Despite its modest size, Cloverswale plays a crucial role in ensuring water supply reliability in the region, highlighting the importance of such infrastructure for water resource management and climate resilience efforts.
With its strategic location and function, Cloverswale serves as a vital water management structure in the area, contributing to irrigation and water supply needs. The dam's association with the Tr Witcher Creek and its storage capacity of 4620 acre-feet make it a significant component of the local water infrastructure. Additionally, the regular inspections and state oversight indicate a commitment to maintaining the dam's safety and functionality, underscoring the importance of proper dam management in safeguarding water resources and mitigating potential risks associated with dam infrastructure.

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 Cloverswale
Where does the data for Cloverswale 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.
