AB: Current drought conditions have highlighted socio-economic and resource-related conflicts in arid regions of the western United States. To address one such conflict, decision makers and resource managers have developed an analytical modeling framework to aid in the protection and utilization of water resources in the Tongue River basin in Montana and Wyoming. The modeling framework has been used to study the sources of dissolved solids in and the impact of such sources on in stream water quality. This paper describes the modeling approach, focusing specifically on methodologies developed to assess water diversions and other agricultural water management practices. Efforts to model the impacts of climate and ongoing coal bed methane development are also described. An evaluation of the predictive capability of the modeling framework, including an uncertainty analysis, is presented along with an illustration of its use in forecasting the impact of future coal bed methane development on water quality.
