Lower Tolt River Floodplain Restoration

King County and the City of Seattle are collaborating on a voluntary effort to enhance salmon habitat in the lower Tolt River. The project is currently scheduled for construction in two phases, beginning in July 2008.

The main project area will be along the Tolt River before it joins the Snoqualmie River, in and around Tolt River - John MacDonald Park in Carnation. The project proposal is to set back the existing levee within the park to help return the river corridor to its natural flood-plain character and improve fish habitat.
