There are over 7,000 homes in the Lake Whatcom Watershed. Many of these homes have lawns and gardens that require regular upkeep to keep them looking attractive and healthy. The choices you make taking care of your yard and landscaping play an important role protecting Lake Whatcom. 

Did you know...
Lakes and rivers can be extremely sensitive to small amounts of phosphorus runoff. It takes 20 parts per million (ppm) of soil phosphorus to grow healthy turf; 25 parts per billion (a quantity 1000 times smaller) can promote excessive algae growth in lakes. Preventing even small amounts of phosphorus from getting into the water can make a big difference.

Avoid using pesticides and fertilizers
To help reduce the amount of phosphorus entering Lake Whatcom, Whatcom County and the City of Bellingham passed regulations that restrict the use of phosphorus containing fertilizers on lawns in the Lake Whatcom Watershed.
