Who we are:

Friends of Cottage Lake (FOCL) is a non-profit, community-based group committed to improving and defending the health and continued enjoyment of Cottage Lake in Woodinville, WA.

We are currently working with King County to apply for grant money to help fund various lake improvement projects. In the summer of 2005, our lake was chosen as a recipient of a Centennial Clean Water Fund grant—this grant targets the phosphorus problem and funded water quality monitoring and community outreach programs for 5 years.

FOCL is also working with the community to deal with the water lily problem and the Eurasian Milfoil infestation on Cottage Lake. See the links for more information.
