Lake of the Ozarks / Osage Region 7 counties
Benton County 19 notes Benton County sits at the meeting of two big water systems: Truman Lake, a Corps of Engineers reservoir behind Truman Dam, and the far upper end of Lake of the Ozarks, which is Ameren-managed. Camden County 32 notes The heart of Lake of the Ozarks: lake property layers extra rulebooks (dock permits from the lake manager, private roads/POAs, lake-area sewer districts, short-term-rental rules), county lines split coves, and karst and a marquee state park shape the geography.
