What’s new:

The lake was treated on Monday, August 1st with ProcellaCOR. It takes about 2-3 weeks for the milfoil to respond to the herbicide – in the short term you may see some additional growth, but in 2-3 weeks the milfoil should wilt to the lake bottom

A community Meeting on lake treatment options was held on May 14th. You can view the presentation from Aquatechnex here. Aquatechnex will be back on the lake to do an invasive plant survey (focused on milfoil) the week of May 31st.

Milfoil Update (05/31/22):
We last treated the lake for Eurasian milfoil in June of 2018. Based on the presentation and information provided by Aquatechnex, we are hoping to treat the milfoil this year and are updating our permit to add ProcellaCor (Florpyrauxifen-benzyl) as an option for treatment (faster acting and fewer restrictions than 2,4-D)

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.
