Riparian vegetation was planted along a freshwater creek that drains to the Lower Duwamish.  Off-channel habitat creates refuges for juvenile fish.

This Lower Duwamish restoration project restored riparian stream bed, freshwater marsh, estuarine marsh, and restored fish access to Hamm Creek.  King County, with funding from the Army Corps of Engineers and the Elliott Bay/Duwamish Restoration Program, created 2,300 feet of new stream bed and channel for Hamm Creek. 

The enhanced freshwater channel features meanders, fish pools, and large woody debris.  Native trees and shrubs were planted to create a riparian buffer for the stream.  The intertidal habitat was planted with native estuarine marsh.  The project was completed in 2000 and was monitored by the Elliot Bay/Duwamish Restoration Panel through 2015.
