The current monitoring station locations are shown in the Year 5 NPDES Annual Report (Appendix E) submitted to TDEC. See Notes 4 and 5 for new locations of two monitoring stations.

NOTE 2: Monthly rainfall data files contain the daily rainfall amounts at the five City monitoring stations and at the official NOAA station at McGhee-Tyson Airport.

The city monitoring stations show that there can be a large spatial variation for a particular rainfall event. Rainfall can occur in some parts of the city and not others due to prevailing winds, localized thunderstorms, alignment of ridges and valleys, etc.
