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: Here are the top ten wettest years for the City of Knoxville. The years 2002 and 2003 have been very wet but do not qualify for the list. Keep in mind that rainfall-measuring techniques have changed over the years.
