Sometimes you can really get upset when you see the things that people have the nerve to throw in the river. Well, in this case, hold your temper for just a moment. The string that you see tied to the rock in the upper left hand corner is actually a part of an experiment that will help us to gauge the health of the river. At the end of the string, tucked up against the rock is a leaf pack, a mesh bag carefully filled with local leaves by Bob Ward and his wife Hilela. The leaf pack will stay in the river for just over three weeks and hopefully become a home for macroinvertebrates. The pack and others like it will be removed and students from local high schools will carefully comb through them to find what life there is to find.
