Water transfer data were collected by the U.S. Geological Survey , in cooperation with the Minnesota Department of Natural Resources, from the 13 hydrologic subregions in Minnesota. About 30,000 acre-ft of water is exported annually from eight of these subregions. Interbasin transfer of water is classified according to type of water conveyance in Minnesota. This information is needed by water-system managers and planners to develop water budgets for major river basins, to examine the extent of existing interbasin transfers, and to evaluate the feasibility of transferring water to meet regional water demands.
