Toketee dam
Toketee
Toketee, a privately owned hydroelectric dam located in Idleyld Park, Oregon, stands as a significant structure along the North Umpqua River. Built in 1949 by Pioneer Service & Engineering, this earth dam measures 58 feet in height and 1365 feet in length, with a storage capacity of 880 acre-feet. The dam serves a dual purpose of hydroelectric power generation and recreation, drawing water from a drainage area of 258 square miles.
With a spillway width of 315 feet and a maximum discharge capacity of 28,000 cubic feet per second, Toketee poses a high hazard potential due to its hydraulic height of 40 feet. Despite its age, the dam's condition assessment is currently listed as "Not Available," highlighting the need for regular inspections and maintenance to ensure its structural integrity. FERC serves as the primary regulatory agency overseeing Toketee's operations, with a risk assessment rating of moderate (3) indicating ongoing monitoring and risk management measures in place.
Overall, Toketee's presence on the North Umpqua River showcases the intersection of water resource management and climate considerations, as the dam continues to play a vital role in regional energy production and water regulation. As enthusiasts of water resources and climate issues, exploring the history and current status of Toketee offers insights into the complex balance of infrastructure development, environmental impact, and safety considerations in the management of our water resources.

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 Toketee
Where does the data for Toketee 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 High 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.
