The purpose of this data release is to provide the model data sets for the Tsala Apopka lake basin simulations. The purpose of the simulations are to quantify the inflows and outflows in the Floral City, Inverness, and Hernando pools of the Tsala Apopka Lake basin in Citrus County, Florida under different conditions. Hydrologic changes in pool stages, groundwater levels, spring flows, and streamflows caused by the diversion of streamflow from the hydrology were simulated. The site model was used to calculate (1) fluxes between the lakes and groundwater for various hydrologic conditions; and (2) assess effects of rainfall rates, changes in flows through the structures, and groundwater pumping rates on the hydrology of the Tsala Apopka Lake basin. In addition, the model simulates water exchanges (1) between the lakes and the surficial aquifer, (2) between the surficial aquifer and the upper confining unit, (3) between the upper confining unit and the confined Upper Floridan aquifer, and (4) between the lake and the unconfined Upper Floridan aquifer. The development of the model input and output files included in this data release are documented in U.S. Geological Survey Scientific Investigations Report 2018-5055 (https://doi.org/10.3133/sir20185055).
