Bagnell Dam sits in Miller County, and that is where the lake begins Lake of the Ozarks is a built reservoir, and the dam that created it stands on the Miller County side, which ties the county's identity and its eastern lake towns directly to the dam's history and the Osage River below it Eastern-lake docks answer to Ameren under a federal license On the Miller County side of Lake of the Ozarks the shoreline is managed by Ameren Missouri under a federal hydropower license, so dock permits and shoreline rules come from the lake operator in addition to anything the county or city requires Eldon is the inland highway-and-rail town in the county's north Eldon, in the north of the county, grew as a railroad and highway crossroads rather than a lake town, giving Miller County a year-round commercial center distinct from the seasonal lake economy to the southwest Karst means wells, springs, and sinkholes in rural Miller County Miller County sits in karst country, where dissolving limestone creates caves, springs, and sinkholes, which affects rural drinking-water wells, septic placement, and how quickly surface contamination can reach groundwater The Osage River runs through Miller County above and below the dam Miller County is defined as much by the Osage River as by the lake: the river passes the seat at Tuscumbia and continues below Bagnell Dam, which matters for floating, fishing, and floodplain land along the river corridor Tuscumbia is the county seat, but it is not the population center People expect a county's business to happen in its largest town, but in Miller County the seat at Tuscumbia is a small Osage River community while Eldon and the lake-area towns hold more of the population, so courthouse errands and where people actually live are in different places
