The Lower Wisconsin State Riverway Board is composed of nine citizen members who serve staggered three-year terms. Six members represent each of the riverway counties and are nominated by the respective county boards and then appointed by the Governor. The county representatives must be either a local elected official representing lands within the riverway or a resident of a town with lands within the riverway or a resident of an incorporated municipality that abuts the riverway. Three "at-large" members represent recreational user groups and are appointed by the Governor subject to Senate confirmation. The board employs an executive director and executive assistant as staff.
