Rivers may fall under the categories of natural, scenic, or recreational. These rivers are designated, acquired, and preserved by the state, and development on or adjacent to these rivers is limited. In planning for the use and development of waters and surrounding areas, a full review and evaluation of the river as a scenic resource will be conducted, and the environmental impact of the proposed use and development will be determined. Proposed development projects must be submitted to the Department of Natural Resources for review. In addition, the Department may choose to acquire water use, scenic, and land use easements for these rivers on behalf of the state. The Department may also elect to establish a River Commission for a river designated as natural, scenic, or recreational; the commission will manage the issuance of permits relevant to that river segment. Currently, only three river segments have been designated under this program; they are described on the DNR website.
