The dam is privately owned and regulated by the Washington Department of Ecology, with state jurisdiction, permitting, inspection, and enforcement in place. The earth dam stands at a hydraulic height of 28 feet, providing a storage capacity of 10 acre-feet and covering a surface area of 9 acres. The drainage area for the dam is 0.08 square miles, with a high hazard potential and a poor condition assessment as of May 2018.
The dam is situated on Tr-Murden Cove, within the Seattle District and Congressional District 06 of Washington. The structure is primarily made of stone core and rests on a soil foundation. Despite its high hazard potential, the dam has not undergone any modifications in recent years and lacks specific risk management measures or emergency action plans. The last inspection conducted on the dam was in August 2017, with an inspection frequency of 5 years. Overall, Koura Dam serves as a critical water resource for irrigation in the region, but its condition and hazard potential warrant careful monitoring and maintenance moving forward.
