Canyonville Reservoir dam
Canyonville Reservoir
Canyonville Reservoir in Oregon, managed by the local government, serves as a critical water supply structure along the West Fork Canyon Creek. Completed in 1983, this concrete dam stands at a height of 58 feet, with a storage capacity of 300 acre-feet and a drainage area of 7.4 square miles. With a maximum discharge of 3783 cubic feet per second, the reservoir covers an area of 18 acres and plays a vital role in water resource management in the region.
The dam's primary purpose is water supply, and it boasts a significant hazard potential, necessitating regular inspections every three years. The reservoir features needle outlet gates and has not been rated for its condition assessment. Despite its critical role in water management, the dam lacks updated emergency action plans and inundation maps. With its location in Douglas, Oregon, and under the regulatory oversight of the Oregon Water Resources Department, Canyonville Reservoir serves as a key infrastructure for water resource enthusiasts and climate advocates interested in sustainable water management practices.
Overall, Canyonville Reservoir stands as a vital water supply structure in Oregon, providing essential services to the local community while facing significant hazard potential. Its construction in 1983 and subsequent management highlight the importance of water resource infrastructure in the region. For water resource and climate enthusiasts, the reservoir serves as a focal point for understanding the challenges and opportunities in sustainable water management and the need for updated emergency preparedness measures.
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 Canyonville Reservoir
Where does the data for Canyonville Reservoir 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.
