unpleasant surprise

     As usual, we went to our lake at the end of November. The weather was suitable for swimming .. It was empty and silent, and extremely humid. Though there is no long green views were stunning. When we approached the water did we have a very unpleasant surprise. Everywhere on the surface of the water was blue-green from blue-green algae. We went to the banks but everywhere was the same. The end of the bath. Until next year.
