Management Areas

 

East King County Groundwater Management Area MapThis Groundwater Management Area encompasses nearly 225 square miles mostly within the Snoqualmie River Valley. The boundaries extend from the Snohomish -King County border to areas south of North Bend, bounded on the east by the foothills of the Cascade Mountains and on the west by the surface water divide between Bear Creek and Snoqualmie River

Most of the residential, commercial and industrial land uses are within the cities of Carnation, Duvall, North Bend, and Snoqualmie.  The remainder of the management area outside the cities' limits has low density residential, forest and agricultural land uses.

Almost 90% of the water used for private, municipal, and industrial and agricultural purposes in the East King County Groundwater Management Area is provided by groundwater sources.
