To evaluate the hydrologic budget of \nthe lower ACF River Basin, a groundwater-flow model, constructed using MODFLOW-2005, was \ndeveloped for the Upper Floridan aquifer and overlying semiconfining unit for 2008\u201312. Model input \nincluded temporally and spatially variable specified recharge, estimated using a preliminary version \nof a Precipitation-Runoff Modeling System (PRMS) model for the ACF River Basin, and pumping, \npartly estimated on the basis of measured agricultural pumping rates in Georgia. The model was \ncalibrated to measured groundwater levels, and base flows which were estimated using hydrograph \nseparation. The simulated groundwater flow budget resulted in a net cumulative loss in groundwater \nstorage during the study period. Spatial variability in simulated hydrologic budgets for eight subbasins \nwas attributed to such factors as soil storage capacity, Lake Seminole impoundment, and the \npresence of in-channel springs. The model simulated a net storage loss for all the subbasins. The \nmodel is limited by its conceptualization, the data used to represent and calibrate the model, and \nthe mathematical representation of the system; therefore, any interpretations should be considered \nin light of these limitations. In spite of these limitations, the model provides insight regarding water \navailability in the lower ACF River Basin.
