One species, creek chub, was found in Carbon Run both upstream and downstream of the treatment system. Creek chubs are insectivores which feed on small aquatic insects. Some of these fish were present upstream before the treatment began, but no fish were present downstream before treatment. One of the larger chubs found in Carbon Run. BAMR has also lowered Carbon Run to near its original elevation, making this crossing more stable.
Treated water flows through culvert, under the stream, into the last treatment pond.
