On January 22, 2008, Tampa Bay Water submitted two petitions for reclassification from Class III waters to Class I waters: (1) the Alafia River between Bell Shoals Road and the confluence with the North and South Prongs of the Alafia River, including Fishhawk Creek and Little Fishhawk Creek, but excluding Turkey Creek, Medard Reservoir and tributaries thereto; and (2) the Tampa Bypass Canal and the Harney Canal as delimited by Structure S-160 on the south, Structure S-163 on the north, and Structure S-161 on the west. Both areas proposed for reclassification lie entirely within Hillsborough County and are currently used for water supply purposes.
