Lake Samish Comprehensive Stormwater Plan
The Lake Samish Basin is an 8,020 acre watershed located in the southwest corner of Whatcom County, Washington. The basin drains to Lake Samish (an 826-acre freshwater lake) and is a sub-basin of the Samish River Basin which drains to Samish Bay. In addition to providing many recreational opportunities, Lake Samish serves as the primary drinking water source for approximately 95% of residents in the area, most of whom draw their water directly from the lake.
Recent monitoring studies have revealed a decline in the lake water quality due, in part, to sediment and external nutrient loading from development and land use practices within the basin. Since there is no public water treatment and distribution system within the basin, this deteriorating water quality could eventually represent a public health and safety issue. In response to this situation, the Whatcom County Stormwater Division initiated a stormwater planning effort for the Lake Samish Basin in 2009.
After a series of public meetings, research, and engineering analysis, the Lake Samish Basin Comprehensive Stormwater Plan was approved and adopted by the Whatcom County Council on March 11, 2014 (see res2014-014).
