Dosser Reservoir Dam dam
Dosser Reservoir Dam
Dosser Reservoir Dam, located in Veradale, Washington, is a privately owned structure regulated by the Washington Dept of Ecology. Completed in 1959, this earth dam on Quinnamose Creek serves the primary purpose of irrigation, with a storage capacity of 55 acre-feet and a surface area of 9.5 acres. The dam stands at a hydraulic height of 14 feet and a structural height of 10 feet, with a length of 950 feet.
Despite being classified as having a low hazard potential and not yet rated for condition assessment, Dosser Reservoir Dam is subject to regular state inspections, permitting, and enforcement to ensure its safe operation. The dam's location in Spokane County, within Congressional District 05, adds to its significance as a water resource infrastructure in the region. With a maximum discharge capacity of 597 cubic feet per second, Dosser Reservoir Dam plays a crucial role in supporting irrigation activities in the surrounding area.
As an essential component of the local water management system, Dosser Reservoir Dam contributes to the sustainable use of water resources for agricultural purposes. Its presence on Quinnamose Creek, with a drainage area of 5.8 square miles, underscores the importance of maintaining and monitoring this structure to ensure the safety and reliability of water storage and distribution for the community. With a focus on irrigation and a history of service since the mid-20th century, Dosser Reservoir Dam stands as a vital infrastructure asset in the region's water supply network.

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 Dosser Reservoir Dam
Where does the data for Dosser Reservoir 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.
