About this site

Help us monitor the Nine Mile Run stream and its surrounding ecosystem! At this station, you will capture the outflow of a combined sewer overflow (CSO). A CSO is designed to only discharge during storm events; however, this CSO tends to discharge continuously. You can help us monitor the discharge from this CSO by contributing your photographs. This Chronolog project is supported by the National Science Foundation under Grant No. 1939977.
