This project is identified as a priority acquisition in King County's 'Last Best Places in the Green River Watershed', State Parks Gorge Preservation plan, by the WRIA 9 Steering Committee and by King County Executive Ron Sims. The project would protect 270 acres of forested uplands along the last wild section of the Green River Gorge. The project would also protect the instream flows of Icy Creek. Icy Creek is a year round spring fed stream with flows of 40-60 cubic feet per second. It has been classified as a source of clear, cold, pathogen-free water that feeds the Green River. Chinook, coho, and steelhead spawn at the mouth of Icy Creek as it enters the Green River. It also protects numerous spring that feed into the Green River. There are five or more springs that either directly flow into the Green River or flow into Icy Creek from the gorge walls below the Icy Creek uplands.
