Cannon Ranch dam
Cannon Ranch
Cannon Ranch, also known as Cannon Reservoir, is a privately owned water supply dam located in Butte, California. This earth dam, completed in 1870, stands at a height of 18 feet and has a storage capacity of 176 acre-feet. Situated along the Tr Oregon Gulch stream, the reservoir serves as a vital source of water for the surrounding area, covering a surface area of 33 acres and draining a 0.52 square mile watershed.
Managed by the California Department of Water Resources and regulated by the Safety of Dams agency, Cannon Ranch is subject to regular inspections to ensure its structural integrity and safety. The dam has been deemed to have a significant hazard potential but is assessed to be in satisfactory condition as of September 2017. Emergency action plans and risk assessments are integral components in the ongoing management of this essential water resource infrastructure, although specific details on these aspects are not provided in the available data.
With its historical significance, essential role in water supply, and regulatory oversight to ensure public safety, Cannon Ranch represents a key piece of California's water resource infrastructure. Its presence along the Tr Oregon Gulch stream highlights the importance of maintaining and monitoring such structures to safeguard against potential hazards and ensure reliable water access for the local community.
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 Cannon Ranch
Where does the data for Cannon Ranch 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.
