The North \nFork Red River aquifer is an alluvial aquifer that discharges groundwater to the North \nFork Red River, which provides inflow to Lake Altus, an important water source for the \nsurrounding communities. The impact of climate variability on hydrologic systems and \nthe resulting effects on basins has become an important topic in assessing future water \nresources.  Global climate projections from general circulation models, including the \nCoupled Model Intercomparison Project Phase 5 (CMIP5), have been developed to \nimprove the understanding of climate science and forecast future climatic conditions. \nDue to the impact of climate variations on groundwater resources, it is important to \ncommunicate the ranges of results with water resource managers. To approximate a \nrange in future base flow conditions and flow into Lake Altus, the Coupled Model \nIntercomparison Project Phase 5 climate data was downscaled to watershed scale \nusing monthly Bias-Correction Spatial Disaggregation techniques. A time-series of \nscaling factors were developed and interpolated for three climate scenarios (central \ntendency, warmer/drier, and less warm-wetter) representing a range of future climate \nconditions for the period 2045\u20132074. These scaling factors were then applied to an \nexisting soil-water-balance model dataset with climate data for the baseline period \n1980\u20132009 to produce recharge and evapotranspiration estimations for this future \nperiod. The downscaled climate data was applied to the finite-difference numerical \ngroundwater-flow model of the North Fork Red River aquifer using MODFLOW-2005 \nwith the Newton formulation solver (MODFLOW-NWT) which was temporally discretized \ninto 373 monthly transient stress periods representing the period 1980\u20132010. Three \nclimate scenarios (central tendency, warmer/drier, and less warm/wetter) representing \na range of future climate conditions for the period 2045\u20132074 were simulated.
