Lake Susan

Saturday morning. Sunny and cold. I wandered along the path that runs adjacent to Lake Susan. A low mechanical hummmmmm prevailed, along with the steady rumbling of a mechanical freshette.
Open water sparkled. The DNR had cordoned-off a section of the water front and was "aerorating" the shallow lake to fend off fish kill.
Nearby a boat labeled "Rescue" was dropped, upturned in the snow.
