Walker Reservoir 2 dam
Walker Reservoir 2
Walker Reservoir 2 in McMinnville, Oregon, is a privately owned earth dam structure completed in 1977 for irrigation purposes. With a height of 10 feet and a storage capacity of 200 acre-feet, this reservoir plays a critical role in providing water for agricultural activities in the region. Located along the South Yamhill River, this reservoir covers a surface area of 17.7 acres and has a normal storage capacity of 152 acre-feet.
Managed by the Natural Resources Conservation Service, Walker Reservoir 2 has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite its age, the dam has a structural height of 12 feet and a hydraulic height of 7 feet, ensuring its stability and functionality. The last inspection conducted in April 2013 found no significant issues, with an inspection frequency of every 6 years.
As part of the state-regulated infrastructure, Walker Reservoir 2 is subject to regular inspections, permitting, and enforcement by the Oregon Water Resources Department. Its strategic location and reliable water supply make it a crucial resource for sustaining agricultural activities in the area. Enthusiasts of water resources and climate will find Walker Reservoir 2 to be a fascinating example of how private ownership and state regulation can work together to manage and utilize water resources effectively for irrigation purposes.

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 Walker Reservoir 2
Where does the data for Walker Reservoir 2 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.
