Since 2006, Phinizy Center for Water Sciences has been monitoring the water quality in southeastern river basins using autonomous sondes equipped with probes that measure and record temperature, specific conductance, pH, and dissolved oxygen levels at 15-minute intervals.  Currently, our real-time monitoring data covers miles on both the Savannah and Ogeechee Rivers.

Live data from this project is available to the public.

Through this monitoring program, we have

  • produced the most geographically and temporally comprehensive water quality dataset in the history of the Savannah River,
  • supplied this data to the Georgia EPD and US EPA who used it to refine river water quality models,
  • provided insights into how the river functions, including the effects of dams and the importance of the Augusta shoals, and
  • presented findings at scientific meetings.


In 2012, due to generous support from public and private donations, we began transitioning this monitoring network to a real-time, web-accessible system.  Anyone with internet access can now view current and historic water quality data from our Savannah River network.  This access is proving highly useful to a wide range of Savannah River stakeholders, including anglers, boaters, fisheries scientists, and municipal water suppliers.  Our goal is to expand this program to neighboring river and stream basins in an effort to increase our understanding of rivers and promote good stewardship.
