Summary

Designed by J-U-B Engineers and completed in 1996, this offstream dam stands at a height of 44 feet and has a storage capacity of 1683 acre-feet. The dam serves as a vital source of process water for the food processing operations of McCain Foods, contributing to sustainable water usage in the region.

Located on the Kansas Prairie Drain, this Earth-type dam covers a surface area of 11.5 acres and has a drainage area of 0.11 square miles. With a high hazard potential, the dam is inspected every five years to ensure its structural integrity and satisfactory condition. The facility is regulated by the Washington Department of Ecology, with state permitting, inspection, and enforcement mechanisms in place to ensure compliance with regulatory standards. These measures help to mitigate risks and safeguard the surrounding environment and communities from potential hazards.

In the Congressional District 04 of Washington, the Mccain Foods Process Water Storage Facility plays a critical role in water management and climate adaptation efforts. With its strategic location and efficient design, the facility demonstrates the importance of private sector engagement in sustainable water resource development. As climate change impacts continue to pose challenges to water availability, facilities like this serve as essential components of a resilient water infrastructure system that supports both industrial needs and environmental conservation goals.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
