New Dock Size Limits

AmerenUE regulates docks, seawalls and other structures on Missouri’s Lake of the Ozarks under provisions of its federal license for Bagnell Dam and the Osage Power Plant, which created the lake in 1931.

AmerenUE developed the following guidelines after consulting with a task team made up of representatives of the Missouri State Water Patrol, Missouri Department of Conservation, developers, public officials, dock builders, marine dealers and local residents. AmerenUE also solicited public opinion and received support for the guidelines from the majority of those that commented. The guidelines reflect the strongest recommendations from the task team and the general public.

New Dock Size Limits:
Cove or Channel Width	Maximum Dock Length
Up to 500 feet	25 feet from the center of the cove or channel, or 1/3 of the cove/channel width—whichever is more limiting—up to a maximum of 100 feet
More than 500 feet (cove setting)	20 percent of the cove width, up to a maximum of 350 feet*
More than 500 feet (channel setting**)	25 percent of the channel width, up to a maximum of 350 feet*
*Permit requests for docks that are more than 200 feet long will be subject to review by the Missouri State Water Patrol and other agencies as appropriate. **Channels are the main arms of the Lake of the Ozarks: Osage, Gravois, Grand Glaize, Niangua and Little Niangua.
