Our TU chapter had a guide with a "point" reference to monitor water quality. We used bug sampling with the free fly tying and fly casting once a month. This method is used by many agencies to check water quality. Interesting to see what critters live below the surface. Read that 90% of what a trout eats is under the surface.
