Sammamish Shoreline and Stream Restoration at George Davis Creek

Private residence
Sammamish, Lake Sammamish, WA

Residents of a contemporary Lake Sammamish home are enjoying watching kokanee salmon spawn in a creek in their front yard.  The Watershed Company worked closely with the property owners at the mouth of George Davis Creek to reconstruct both the stream channel and lake shoreline to restore riparian and aquatic habitat, while also reducing the regulated critical area buffer to allow home reconstruction. George Davis Creek, cut off from anadromous fish use for decades, once flowed through pipes under the property’s original single-family residence; now, an open channel salmon-spawning stream flows below a new 3-story home.  The Watershed Company navigated the design through local, State, and federal permits without revisions, receiving federal approval within 2 months.  Construction was completed in summer 2009.  In fall 2009, kokanee salmon returned to George Davis Creek for the first time in decades, finding more than 100 feet of spawning habitat along the newly created channel (see video).  They have returned yearly since.

George Davis Creek now connects naturally with Lake Sammamish in this resident's front yard.

Before restoration, the stream was piped under the original house, and cut off from fish use.
