The United States Geological Survey (USGS) owns/operates three existing continuous, real-time water discharge and gauge height stations, one each at the mouths of Conewago Creek, Codorus Creek, and Muddy Creek. Last fall, these three stations were updated to add continuous, real-time water quality monitoring for the indicator parameters of temperature, specific conductance, dissolved oxygen, pH, and turbidity. This spring, three new gauge stations will be installed, one each at Fishing Creek (near Goldsboro), Kreutz Creek (near Wrightsville), and Fishing Creek (near Craley). Additionally, all six stations will have CRT water quality sensors installed to measure nitrogen and phosphorous. Below are links to the current monitoring stations installed.
