The calibrated model, which uses \nMODFLOW-NWT version 1.1.2, simulates hydrologic changes in pool stages, groundwater levels, \nspring flows, and streamflows caused by the diversion of streamflow from the Withlacoochee River \nto the Tsala Apopka Lake basin through water-control structures. A surface-water/groundwater flow \nmodel was developed using hydraulic parameters for lakes, streams, the unsaturated zone, and the \nunderlying surficial and Upper Floridan aquifers estimated with an inverse modeling calibration \ntechnique. After calibration, the model was used to assess the relation between inflows and outflows \nin the Tsala Apopka Lake basin and changes in pool stages. Simulation results using the calibrated \nsurface-water/groundwater flow model showed that the largest leakage rates from the pools to the \nUpper Floridan aquifer occurred at the deep lake cells and that these leakage rates were higher than \nany recharge rates to the Upper Floridan aquifer in the model area. There was downward leakage to \nthe Upper Floridan aquifer in most of the Floral City, Inverness, and Hernando pools. The calibrated \nsurface-water and groundwater flow model was used to simulate hydrologic scenarios that included: \nsmall changes in rainfall rates, projected increases in groundwater pumping rates for 2025 and 2035, \nno flow for the entire period through the eight water-control structures in the Tsala Apopka Lake basin, \nand the removal of the Inglis Dam and the Inglis Bypass Spillway on Lake Rousseau.
