To the editor:

It’s that time of year again: Blue-green algae is blooming in Goss Lake. Dead wood is floating in the high water. The county has posted warnings at the Goss Lake public access due to the presence of toxic algae. The concentration of Anatoxin-a, aka “very sudden death factor” was 2.6 ug/L when tested in late November. King and Island counties ran out of funds to perform the required re-testing of the lake water in 2012.

Anatoxin-a is toxic to people, pets, fish, ducks, deer, in fact most, if not all, species that rely on lake water for survival. Fortunately, our families and pets have access to other water sources. The algae growth is fueled by run-off at this time of year.

Many thanks to Goss Lake neighbors who have secured floating logs on their property: the cellulose-digesting bacteria in the wood require soluble nitrogen obtained from the water which in turn reduces the nitrogen available for algae growth. Many thanks to neighbors who will tolerate floating woody debris on their shoreline. Beefing up the amount of downed wood in the lake can help tip the balance away from toxic algae growth. Many thanks to neighbors who are considering replacing weeds and hardscape on their property with native plants. OK, so I don’t know anyone removing hardscape (yet), but any efforts to reduce run-off into the lake are welcome!
