Ocoee Middle; I think I have decided on doing a project on water quality in some trout rivers in our area based on bug populations. You know like using a seine and knocking loose stuff upstream, it drifts down and gets caught in the net. Then, you take a count on the different bugs, and since only certain kinds of bugs can live in certain water qualities, you can roughly determine a streams quality. Plus, it's an excellent excuse to try out the fly rod.
