The Lake Whatcom Reservoir is the source of drinking water for approximately half of Whatcom County residents and Lake Samish serves as a water supply for many lakeshore residents. Both Lake Whatcom and Lake Samish support multiple beneficial uses including recreation and fisheries. These benefits enhance the environmental, recreational, cultural, and economic resources of the area and contribute to the general health and welfare of the public. Excess phosphorus entering Lake Whatcom and Lake Samish has been identified as a significant factor contributing to algal growth and low dissolved oxygen conditions in certain portions of the lake at particular times of the year. These conditions may lead to increased treatment costs for drinking water and impair other beneficial uses of the lake. The purpose of this chapter is to promote improvement in lake water quality by limiting phosphorus entering Lake Whatcom and Lake Samish due to the application of commercial fertilizers to residential lawns and public properties within the Lake Whatcom and Lake Samish watersheds.
