Ten students enrolled in the Environmental Science class at RCHS met with Jay Gilliam, coordinator of the Izaak Walton League’s Save Our Streams Program. He led them through two biological water quality tests close to the Rappahannock Park where they learned to scientifically collect and classify “critters,” as he calls them.
The students did seem to mind the 62-degree water which they subsequently scored as “excellent” in water quality rating.
They began by searching the stream for a riffle, four to seven inches deep, where the water was aerated when rushing over rocks thereby adding oxygen. One square yard of the riffle was examined by securing a seine net about four feet square to the stream bottom with rocks. Cobblestones (rocks three to ten inches in size) in the collection site were picked up and gently rubbed to dislodge any aquatic macro invertebrates.
