scatter creek watershed

in Southern Thurston County. Scatter Creek is an intermittent stream, and flow is discontinuous in the summer and fall months. Headwaters drain from gentle hills in Forestry, but much of the watershed is covered with excessively drained gravel soils from glacial outwash, historically covered by Prairie and Oak Woodlands. Land Use changes and Groundwater pumping have altered the hydrology of Scatter Creek. Confederated Tribes of the Chehalis Reservation fished for lamprey and salmon in Scatter Creek. The prairies surrounding Scatter Creek were cultivated for camas, berries, and other important medicinal and nutritional foods, using controlled burns to sustain the plant diversity that the prairies provide. Historically Scatter Creek was home to abundant runs of lamprey and various salmonids, with historical records depicting year-round flows and ample groundwater springs. Beaver likely had a strong historical influence on the geomorphology and hydrology of the stream. Scatter creek is now primarily a Coho Salmon stream with spawning and rearing throughout the watershed. Steelhead use the bottom of the system near where it enters the Chehalis River (at river mile 55.2). The main habitat limiting factors include stream flow losses/disconnected flows, warm water temperatures/lack of cold water refugia, and fragmented riparian areas. An intense strategic planning process was initiated as part of the Aquatic Species Restoration Program with funding from the Office of the Chehalis Basin
