About this water

The Milwaukee River is Wisconsin's major urban Lake Michigan steelhead tributary, where salmon, steelhead and browns move into very visible city water. It needs urban-access handling, current WIDNR access links and a clear distinction between lower-river migratory fishing and broader watershed context.
