West Plains Hydrogeologic Framework Project

The goal of this project was to gather, evaluate, analyze and synthesize all existing hydrogeologic data and studies to develop and document a detailed assessment of the hydrogeologic framework and a conceptual model of the groundwater flow system of the West Plains.  The intended uses of the hydrogeologic framework and conceptual groundwater flow model are for water management decision making, including pending water right applications, and as the foundation of a transient numerical groundwater flow model.  The project was completed on June 30, 2015.  The final report is available for download below.
