Summary
Built in 1970, this Earth-type dam stands at a structural height of 23 feet and spans a length of 2083 feet. With a normal storage capacity of 84 acre-feet and a maximum storage capacity of 123 acre-feet, this dam plays a crucial role in water resource management in the area.
Situated on the Tr-Esquatzel Coulee, the Con Agra Foods Main Storage Basin Dam is regulated by the Washington Department of Ecology and undergoes state inspections and enforcement procedures. Despite its low hazard potential, the dam's condition has not been formally assessed. The dam serves various purposes beyond flood control, and its location in Franklin County makes it an important structure for the surrounding community.
As a significant feature in the region, the Con Agra Foods Main Storage Basin Dam not only supports agricultural activities but also contributes to the overall water resource management in Washington. Its strategic position and design make it an essential part of the local infrastructure, ensuring water availability and flood protection for the area. With state oversight and regulatory measures in place, this dam plays a vital role in maintaining the environmental and economic stability of the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
