Mcdowell Lake Dam dam
Mcdowell Lake Dam
Mcdowell Lake Dam, located in Arden, Washington, serves as a vital recreational resource within the Little Pend Oreille Game Range. Completed in 1973, this earth dam stands at a hydraulic height of 16 feet, with a structural height of 13 feet, and a length of 615 feet. With a storage capacity of 596 acre-feet and a surface area of 33 acres, the dam primarily caters to fish and wildlife pond enthusiasts, as well as recreational activities.
Despite its low hazard potential, the dam's condition assessment is marked as poor, with the last inspection conducted in October 2010. The Washington Department of Ecology regulates and inspects the dam, ensuring its compliance with state standards. With a drainage area of 1.88 square miles and a maximum discharge capacity of 197 cubic feet per second, the dam plays a crucial role in managing water resources within the region.
As climate change continues to impact water resources, the maintenance and upkeep of Mcdowell Lake Dam are essential to ensure its continued functionality and safety. With its picturesque location along the Little Pend Oreille River, the dam remains a significant asset for both wildlife preservation and outdoor recreation in Stevens County, Washington.
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 Mcdowell Lake Dam
Where does the data for Mcdowell Lake 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.
