Mcnary Lock And Dam - Kennewick Levee 7 dam
Mcnary Lock And Dam - Kennewick Levee 7
Mcnary Lock and Dam, situated in Oregon along the Columbia River, is a vital structure owned and operated by the US Army Corps of Engineers for flood risk reduction. Completed in 1952, this earth dam is part of a larger system of 12 associated structures aimed at managing water levels and preventing potential flooding in the area. The dam's primary purpose is to mitigate the risk of inundation and protect the surrounding communities from the hazards posed by high water levels.
With a high hazard potential, the US Army Corps of Engineers closely monitors and manages the flood risks associated with the dam. Regular inspections, emergency action plans, and risk assessment measures are in place to ensure the structural integrity of the dam and the safety of the nearby residents. By working collaboratively with local emergency managers and the public, the Corps aims to raise awareness, prepare for emergencies, and respond effectively in the event of a dam-related crisis. As climate change continues to bring unpredictable weather patterns, the importance of proactive risk management strategies at Mcnary Lock and Dam becomes increasingly evident, showcasing the critical role it plays in safeguarding the community against potential flooding events.
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 Mcnary Lock And Dam - Kennewick Levee 7
Where does the data for Mcnary Lock And Dam - Kennewick Levee 7 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.
