Visual Stream Assessments
Local Stream Studies
In 2017, the Stormwater Department began sampling Clark Branch and Tranbarger Branch, as part of a study to gather more data on the health of these two streams. Both streams are listed by the U.S. EPA as having high E. coli levels and excess siltation. Siltation affects the ability of aquatic insects and fish to live in the creek, and E. coli affects human health. Water samples are being tested for bacteria, and aquatic insect larvae are being collected and identified.
