The South Dakota Water Resources Institute Records consist of departmental publications, reports, administrative materials, and collected research related to water quality, irrigation, and resource management. Materials include annual reports, operating budget documentation, informational pamphlets, and photographic records. A significant portion of the collection pertains to the Missouri River Basin Project, encompassing a wide range of technical reports, feasibility studies, environmental impact statements, and planning documents. These reports address critical issues such as irrigation development, water quality standards, aquifer management, flood control, channel degradation, hydrology, and the economic and environmental implications of water resource use.

This collection documents the Institute’s role in advancing water research and policy in South Dakota and the broader Missouri River Basin region. The records reflect federal-state collaboration under programs like the Pick-Sloan Missouri Basin Program and include contributions to state and national discussions on sustainable water use, agricultural irrigation, and environmental protection. The depth and breadth of the Missouri River Basin Project materials provide valuable insights into mid- to late-20th century water management initiatives and the scientific, economic, and political challenges surrounding them. Researchers interested in water resource development, environmental policy, agricultural engineering, and regional planning will find the collection especially valuable.
