The Green River is the source of water for a regional partnership formed by the City of Kent, the Covington Water District, the Lakehaven Utility District and Tacoma Water.
This complex in Enumclaw, WA has three lakes that that are entirely in public ownership or in partial public ownership. The plans are to improve and preserve existing water quality and vital habitat in the lakes complex. There will be a network of trails that connect the lakes to the Green River Gorge Greenway.
Additionally MGRC and King County have embarked on a comprehensive program to restore the habitat of the area through site planning, removal of invasive species, and replanting with native plants.
This land protects an important subwatershed of lakes, Cristi Creek, and wetlands that feed the Green River. The complex connects to the larger Green River Gorge Mountains to Valley Greenway.
The Lower Soos area is State Department of Fish & Wildlife land located near Highway 18 across the Green River near the Neely Mansion near Auburn, WA.
Thanks to a private grant, MGRC is working to remove invasive Rubus armeniacus (commonly known as Himalayan blackberry) without using pesticides or herbicides. This process will not only be important for salmon spawning and other wildlife, but it will also help to keep water temperatures constant, which is currently a problem along Lower Soos Creek at its confluence with the Green River.
The first phase included mowing to remove the well-established blackberries that have overrun the area for many years and then and placing landscaping fabric to prevent re-growth of these invasive plants. This fabric will remain staked down and in place for 2 to 3 growing seasons.In the final phase, native plant species will be planted in the area formerly occupied by non-native blackberries.
What is the Middle Green Subwatershed?
The Middle Green River Subwatershed starts at River Mile 32 just east of Auburn and stretches to the Howard Hanson Dam.
It includes two major tributaries:
Soos Creek on the north side of the river, draining Kent, Covington, Maple Valley, and Black Diamond and Newaukum Creek on the south side of the river, draining the Enumclaw area.
