Abstract

Planning the Development of South Dakota water and related land resources is an important and difficult task which required integration of a large amount of basic data. Planning also implies projection of future conditions for decision making. Accomplishing the planning process normally required analysis of many alternatives which requires the combination and recombination of the basic data. This study inventoried rh presently available data on water supply and water demand I western South Dakota. The data was organized around a central data framework based upon the Leonteif input-output model. This data organization concept requires a complete accounting of water supply and use. A mass balance constraint is applied to each element in the system., i.e. all water received (input) by element must be discharged (output) by the element. In addition, considerations which are unique to the western South Dakota problem area were incorporated into the analysis. Water quality and minimum instream flow requirements for environmental maintenance were included into water resource system analysis. Because available data has not necessarily been collected for similar application, the level of detail is rarely comparable. Thus it is highly desirable to be able to aggregate data to a common level of detail for comparison and analysis. The input-output concept permits this aggregation to be accomplished in a straight forward and simple manner. The primary foci of this study are summarized in the objectives. 1. Classify water demands into related categories for summarization and make projections of those demands for the next 50 years. 2. Organize available data around a framework which permits meaningful comparisons between data of varying levels of data. 3. Incorporate instream flow requirements and water quality data into the water resource system analysis. 4. Determine the present water supply-demand problems in western South Dakota. 5. Evaluate the input-output model as a tool for analysis of future South Dakota water supply-demand problems.
