RiverWare simulated daily averaged surface water permit requested diversions and diversions modeled in the spatially refined model region within the Red River Basin. Values reported are for 18 different climate projection scenarios and a historical scenario, from 2010 through 2099 and 1976 through 2005, respectively. The RiverWare model was used to determine the impacts on regulated flows, resevoir levels, and water permit reliability. RiverWare was used for this project because of its ability to simulate water use, reservoir operations, and local/interstate regulations.

Daily streamflow and reservoir water elevation data for modeled locations in the Red River Basin. Values reported are for 18 different GCM (Global Climate Model) / RCP (Representative Concentration Pathway) / GDM Downscaling scenarios. Climate data from each scenario was input into a Variable Infiltration Capacity (VIC) model, that output flow values. These values were then input into RiverWare, to determine the impacts on regulated flows, lake levels and water availability. RiverWare was used for this project, because of its ability to simulate water use, reservoir operations, and local/interstate regulations.

In 2015, the Red River Basin experienced the tail end of a severe drought followed by exceptional flooding, both of which cause impacts to industry, agriculture, tourism and the environment. Scientists, water managers and other stakeholders are interested in knowing what is in store for the future of the Red River Basin. Researchers at the University of Oklahoma and the Choctaw and Chickasaw Nations developed projections of future hydrology for the Red River Basin under possible future climate conditions. A methodology was developed for using current state of the art Global Climate Models (GCM) and applying them on a scale suitable for hydrologic models, ultimately making the information useful to water managers...

Several times during the severe drought of 2010-2015, communities within the jurisdictional territories of the Chickasaw Nation and the Choctaw Nation of Oklahoma were precariously close to running out of water. According to previous studies, temperatures are expected to continue to rise throughout the southern states, and droughts are predicted to be longer and more severe. Even small changes to a river’s water flow regime may have unanticipated consequences on the water resources, especially for communities that rely on direct river diversions to supply their needs. A suitable water availability model is a key tool needed to help communities investigate where vulnerabilities in water resources may occur and the...

During the severe drought of 2010-2015, several communities in southeast Oklahoma nearly ran out of water. Some of these communities rely on streams and rivers as their sole source of water, and when these sources almost ran dry, it left them searching for alternatives and wondering how to manage future water uncertainty. To address these challenges this study used historical and climate projections through the end of the century to model potential impacts to individual water permits, and to estimate projected supply-demand curves for the most water vulnerable communities. This study focused on local communities within the Red River Basin in both the Chickasaw Nation and Choctaw Nation territories. Additionally,...
