Section 40B-8.031 - Minimum Surfacewater Levels and FlowsThe Governing Board hereby establishes the following minimum surfacewater flows and levels for Madison Blue Spring. The Governing Board finds that the following minimum surfacewater flows and levels are the limit at which further withdrawals would be significantly harmful to the water resources or ecology.
(1) The minimum surfacewater flow for Madison Blue Spring is 70 cubic feet per second (cfs) for a flow duration frequency of 90 percent when the stage of the Withlacoochee River measured at the Pinetta gauge is 55.0 feet (NGVD) or less.(2) If the surfacewater flows from Madison Blue Spring are reduced below the levels established in subsection (1) above, withdrawals will be significantly harmful to the water resources or ecology.(3) In determining the estimated impact of existing and proposed future withdrawals on the surfacewater flow of Madison Blue Spring, as expressed in subsections (1) and (2) above, the following factors shall be considered: (a) A stage of 55.0 feet (NGVD) at the Pinetta gauge will serve as a modeling boundary condition.(b) The surfacewater flow for Madison Blue Spring shall not be caused to be reduced to a predicted flow of 70 cfs or less for a flow duration frequency of less than 90 percent as determined by the Flow Duration Curve for the Madison Blue Spring discharge over the historic period.Fla.
