Abstract. Real time monitoring and the internet of things are becoming more important tools for water management and regulation. Real time awareness of water quality or stream stage can inform communities against harmful pollutant levels and aid in the prediction of damaging flood events. Permitting agencies that establish limits on pollutants in various water systems such as municipal separate storm water sewer systems (MS4s) and promote guidance towards water management also benefit from real time monitoring for regulatory purposes. Improving current monitoring methods and technologies will benefit both communities and regulatory agencies. To that purpose and others, an extensive network of 24 monitoring sites has been implemented to monitor water quality, water levels, and discharge throughout the stream network of Hunnicutt Creek in Clemson, South Carolina. The stormwater conveyances of Clemson University are collectively classified as a small MS4 (SMS4) and direct water to Hunnicutt Creek which runs adjacent to and through university property. Because of the highly developed areas and extent of impervious surfaces such as roofs, parking lots, and sidewalks, this stream behaves similarly to other urban streams with low baseflow and high-volume flow during storm events and is impacted by stormwater discharges. This presentation will address issues and lessons learned in the real time monitoring of an urban micro watershed related to data management, data corrections, instrument maintenance, and public outreach.
