Kelley Creek Confluence Project

Kelley Creek Confluence Project

Environmental Services completed construction of the Kelly Creek project in summer 2004. The six-acre project at the confluence of Kelley and Johnson creeks restored natural floodplain functions, increased flood storage, and improved water quality and habitat conditions. The work included removing fill and recreating historic meanders in Johnson and Kelley creeks.
Construction crews removed about 24,000 cubic yards of soil to create more than 13 acre-feet of flood storage. New creek meanders provide an additional 200 feet of cold water spawning and rearing habitat for steelhead, cutthroat trout and coho salmon. Two backwater channels were added along Johnson Creek and one on the new Kelley Creek channel to provide wetland habitat, high flow refuge for fish, and floodwater storage.
