Note 1:Rainfall data is collected and maintained by the Stormwater Engineering Division, Suite 480 City County Building (215-2148), as part of the NPDES monitoring program; see the NPDES web page for additional information. 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.

Note 3: Temperature and precipitation records for the official NOAA station at McGhee-Tyson Airport can be viewed at the National Weather Service web page. 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.

Note 4: The monitoring station for First Creek has been relocated in April 2005. It is now located at the KAT station (maintenance yard) on Jessamine Street near Fifth Avenue.

Note 5: The monitoring station for Second Creek has been relocated in October 2005, and is now located on Williams Creek in east Knoxville near Dandridge Avenue.

Note 6: The table below displays the top ten wettest years for the City of Knoxville.  Please keep in mind that rainfall measuring techniques have changed over the years.
