Krumbo Dam dam
Krumbo Dam
Krumbo Dam, located in Harney, Oregon, stands as a testament to the collaborative efforts of the U.S. Fish & Wildlife Service in managing the resources of Krumbo Creek. Completed in 1957, this earth dam serves the primary purpose of recreation while also supporting water supply needs. With a height of 35 feet and a length of 505 feet, the dam boasts impressive storage capabilities, holding a maximum of 5365 acre-feet of water and covering a surface area of 198 acres.
The dam's structural integrity is regularly inspected, with the most recent assessment in August 2018 deeming its condition satisfactory and its hazard potential low. With a moderate risk assessment rating of 3, risk management measures are in place to ensure the safety and stability of the dam. Despite its age, Krumbo Dam has undergone modifications in 1983 to enhance its structural capabilities, ensuring its continued operation and contribution to the surrounding ecosystem.
As a key feature in the Portland District managed by the Fish and Wildlife Service, Krumbo Dam not only provides recreational opportunities but also plays a vital role in water supply management. With its strategic location and reliable performance, this dam stands as a model for sustainable water resource management in the region, highlighting the importance of infrastructure in mitigating the impacts of climate change on water availability and ecosystem health.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Krumbo Dam
Where does the data for Krumbo Dam 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.
