Summary

Standing at 31 feet tall with a structural height of 33 feet, this earth dam provides irrigation water storage of up to 166 acre-feet. With a surface area of 16.8 acres and a drainage area of 0.24 square miles, Moore-Emory plays a crucial role in water management in Benton County.

Managed by the Natural Resources Conservation Service, Moore-Emory is regulated by the Oregon Water Resources Department and undergoes regular inspections to ensure its safety and efficiency. Despite having a low hazard potential and being in a not rated condition, Moore-Emory continues to serve its primary purpose of irrigation for the local community. With a maximum discharge of 33 cubic feet per second, this dam not only supports agriculture but also helps in maintaining a sustainable water supply for the region.

As a key contributor to water resource management in Oregon, Moore-Emory serves as a vital infrastructure for the Kings Valley area. With its strategic location and efficient design, this dam stands as a testament to sustainable water use and environmental stewardship. As climate change continues to impact water availability, the importance of structures like Moore-Emory in ensuring water security for communities cannot be overstated.

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.
