40B-8.101. Minimum Flows and Minimum Water Levels for the Steinhatchee River and Steinhatchee River Priority Springs
1The Governing Board hereby establishes the following minimum flows. The Governing Board finds that the following minimum flows are the limit at which further withdrawals would be significantly harmful to the water resources or ecology.
36(1) The minimum surface water flow for the Steinhatchee River occurs when the cumulative change in flow at the Steinhatchee River Near Cross City, FL gage is greater than 2.07 cubic feet per second (cfs) from a flow that has been unchanged by groundwater withdrawals, surface water withdrawals, or a combination of both.
89(2) The minimum surface water flows for the Steinhatchee River priority springs are established as the following cumulative percent reductions from the median flow of such springs measured at the spring vent or as close thereto as reasonably possible:
128(a) TAY76992: 11.5 percent;
132(b) Steinhatchee Rise: 11.5 percent.
137(3) In addition to the criterion set forth in subsection 40B-8.101(1), F.A.C., a cumulative surface water flow reduction of 11.5 percent of the prior day’s flow at the Steinhatchee River Near Cross City, FL gage when flow is greater than 8.70 cfs and less than or equal to 858 cfs, or a cumulative reduction in flow of 98.7 cfs when flow is greater than 858 cfs and less than or equal to 1,790 cfs, or a cumulative reduction in flow of 5.5 percent when flow is greater than 1,790 cfs does not result in significant harm. For the purposes of this section, the “prior day’s average flow” will be the daily mean discharge in cfs for the previous calendar day measured at the Steinhatchee River Near Cross City, FL gage.
