91(2) In addition to subsection (1) above, the minimum surface water flow for Manatee Spring for the period of November 1 through April 30 is 130 cubic feet per second for a flow duration frequency of 50 percent.
129(3) The minimum surfacewater flow for Fanning and Little Fanning Spring is the flow that will maintain 90 percent of the historic flow regime for the Fanning Spring discharge as defined in “Technical Report – MFL Establishment for the Lower Suwannee River and Estuary, Little Fanning, Fanning, and Manatee Springs, October 2005.”
181(4) The minimum surface water level for Fanning Spring for the period of November 1 through April 30 is 2.71 feet (NGVD) for a stage duration frequency of 85 percent.
211(5) The minimum surfacewater flow for the Lower Suwannee River below the Wilcox gauge is 6,600 cubic feet per second for a flow duration frequency of 50 percent for the period May 1 through October 31.
