What’s new:

Please Read our 2018 letter: State of the Lake 2018

Algae Update (08/30/18):
The latest samples came back above the safe limit for microcystin so the park beaches will be closed to swimming and warning signs will go up. I’ll continue to sample weekly and you can now track the state of the lake on the toxic algae site: https://www.nwtoxicalgae.org/

Milfoil Update (07/20/18):
Woodland Resources treated the lake for milfoil on June 14th. The herbicide level in the latest water samples came back significantly lower than the irrigation restriction level so there are no longer any concerns about using the water for irrigation. See our milfoil page for more information.

Community Meeting: TBD

Water Lilies – treated last year (2017) – waiting to see how things look when the lilies come back up this spring.
See the water lily page for more info.

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.
