MONITORING STATIONS |
| |
The City of Knoxville currently has five wet-weather monitoring stations located in the First, Love, Third, Fourth, & Williams streams watersheds. |
| |
|
NOTE 1: Rainfall data is collected and maintained by the Stormwater Engineering Division, Suite 475 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.
