The Army Corps of Engineers and Lake of the Ozarks

The Lake of the Ozarks is NOT controlled by the The Army Corps of Engineers but by Ameren Missouri.

The Corps remains somewhat relevant to the management and operation of the lake through a "Memorandum of Agreement" (MOA) that exists between Ameren and the Corps of Engineers in coordinating operations with Truman Dam, which is managed by the Corps. As part of the overall river system, Ameren and the ACoE are required by license to reduce erosion and flooding along the lower Osage River and establish "ramp-down" rates after high flow conditions. This means that Ameren must coordinate water management with the Corps in regards to its role in overall flood control strategy for the entire watershed.

The Corps is also responsible for all mile marker assignments along the main channel, a holdover from its days as a navigable river.

More importantly, any projects involving any of the following will require Corps approval. These summaries are taken from Ameren's permit page. The accompanying link should be followed up for more rigorous review.
  • Any activity located lakeward of elevation 658.5ft, affecting a wetland or a rare, threatened, or endangered species (requires review by the Missouri Department of Conservation as well).
  • Placement of heat exchange coils for heat pumps (in conjunction with Ameren approval).
  • Breakwater construction (requires Missouri State Water Patrol approval as well).
  • Construction of seawalls below 658.5ft (allowed only in well documented cases of extreme erosion).
The complete permit documentation for these and other related activities are provided at Ameren's website.
