What’s new:

Toxic Algae Update – 8/12/2020
Many of you reported seeing algae along the shore this weekend. We submitted a sample and here is the reply after testing:

“The sample you submitted had 3 ug/L of microcystin and non detect for anatoxin. The microcystin detection is below the recreational guidelines of 8 ug/L, so lake use can continue as normal. That being said, because there was a detection, please let us know if you see any significant changes in color, consistency, or concentration of algae in the lake (and pictures are always helpful!). We can submit additional samples in the future if needed.”

So, no restrictions, but keep your eyes open for additional blooms and, as always, avoid contact with any algae blooms.

Fundraising Opportunities:

Milfoil Update (07/20/18):
Woodland Resources treated the lake for milfoil on June 14th, 2018. 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.

Water Lilies – last treated in 2017 – watching the remaining lilies – no treatment currently planned.
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.
