Little Cahaba River, above Cahaba Beach, U.S. Geological Survey, SESQA Ecology Sample Site, Jefferson County, Alabama 2

This was one of many streams sampled as part of the U.S. Geological Survey's, Southeast Stream Quality Assessment (SESQA). We looked at fish, algae, and benthic invertebrate communities within either 150 or 300 meter reaches of stream depending on width. It was exhausting but highly rewarding work.
