Before you launch
Official sources and current guidance
The vessel, the water, and the managing agency can change the rule.
Last checked: 2026-06-18. Boating law, fees, and local lake and river rules change — and the water itself changes with the weather and the season. Confirm before you launch, and wear your life jacket.
This is a summary, not the law or a substitute for a boating course. Boating rules and fees change — confirm with the Highway Patrol, the Department of Revenue, and the agency that runs your water. In an emergency, call 911.
Heads up: Ameren manages the Lake of the Ozarks shoreline and project lands inside the federal (FERC) boundary — it does not 'run' the lake. Missouri boating law on the water is enforced by the Highway Patrol (Water Patrol). When a local rule matters — a horsepower limit, an electric-only lake, a no-wake zone, a closure — ask the agency that manages that water.
