Abstract

The South Dakota Water Resources Commission is in the process of developing a State Water Plan to analyze current water and land needs and problems, to set goals of water ·management, and to promote the prosperity and general welfare of the state through wise use and management of the water and land resources. The State Water Plan will inventory the present and future water and related land resources and offer guidance on the management of the state's water resources. In order to facilitate planning, the South Dakota Water Resources Commission has designated 16 major drainage areas in the state including two noncontributing drainage areas. As a result of the study by Rakness, personnel of the South Dakota Water Resources Commission requested the Civil Engineering Department of South Dakota State University to process streamflow data for 75 gaging stations within the state and to assemble similar tables to be used in preparing the State Water Plan. For this investigation, the Upper Mississippi-Minnesota Rivers Basin in South Dakota was selected for study. This river basin is one of 16 major drainage areas designated by the South Dakota Water Resources Commission for the State Water Plan and is also a major hydrologic basin designated by the South Dakota Committee on Water Pollution for water quality management planning. While analyzing the streamflow variation of the Upper Mississippi-Minnesota Rivers Basin, flow records of 72 other stream-gaging stations on major rivers of South Dakota with ten or more years of record were also analyzed to fulfill the request of the South Dakota Water Resources Commission. However, in this study only the two streamflow-duration tables of the gaging stations within the Upper Mississippi-Minnesota Rivers Basin are presented. The main objectives of this study were to determine the seasonal flow duration relationships for gaging stations in the Upper Mississippi-Minnesota Rivers Basin, to compare the seasonal variation of water quality and streamflow, and to investigate the existing water quality data for comparison to the water quality needed for designated beneficial uses of the surface water in the river basin. The results of this study were expected to be of assistance to the South Dakota Water Resources Commission in developing the State Water Plan and the Department of Environmental Protection in developing the Water Quality Management Plan.
