I was driving over the Conestogo dam when I noticed the levels were greatly reduced from the last time I had been in the area. I decided to visit the conservation area and get a closer look. I parked near a beach access point and took a walk to the lake shore. The docks were high and dry looking like marooned rafts. I noticed what appeared to be blue paint at the water's edge and on several rocks. On closer inspection I recognized the dried blue caked substance to be blue green algae. I have also heard it called cyan algae. It is commonly known as pond scum and is made up of microscopic plants that live in fresh water. High phosphorus and nitrogen levels can produce large in blooms in late summer's warm weather. Large areas of water can appear as a bluish green pea soup.
These bird tracks in the dried algae bed made me think of some arts and crafts project taking place not in some public school portable but on the banks of the Grand. I took pictures of these geese and seagull tracks but also noticed raccoon, deer and mouse tracks.
