I was on Google maps checking a route for a trip Fran and I may take later in the fall and something struck me. I clipped a couple pictures from Chatek Lake in Wisconsin after noticing the lines in the algae caused by boats. The lower picture is a closer view of a shoreline. Look familiar? That is scum like we are fighting here. These are 2012 pictures. As I posted before, we are not alone in this fight. Chatek is a huge lake so I am a little surprised. I don't believe it is a compound either, it is river fed as I recall.
