Summary

The dam, primarily serving the purpose of flood risk reduction, is an Earth type structure with a Stone core foundation. Completed in 2009, it stands at a hydraulic height of 32 feet and a structural height of 27 feet, with a length of 840 feet and a storage capacity of 29 acre-feet.

Notably regulated by the Washington Department of Ecology, Mccormick North Phase I East Pond has a hazard potential rated as high, with a fair condition assessment as of June 2018. The dam's inspection frequency is set at every 5 years, ensuring its structural integrity and safety measures are regularly monitored and maintained. With a drainage area of 0.12 square miles and a maximum discharge capacity of 123 cubic feet per second, the dam plays a crucial role in managing water resources and mitigating potential flooding risks in the region.

Overall, Mccormick North Phase I East Pond serves as a significant water resource infrastructure in Washington, contributing to flood risk reduction efforts and ensuring the safety of the surrounding communities. With its strategic location near Anderson Creek and adherence to state regulatory standards, the dam stands as a key component in the region's water management system, highlighting the importance of sustainable and effective climate adaptation measures in the face of changing environmental conditions.

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.
