The Brazeau Bottom is an alluvial floodplain, also called a 'flat', extending along the Mississippi River in Perry County, Missouri.

The flat bottomland on the western bank of the Mississippi River is broken by a series of rocky bluffs, including the Red Rock Landing Conservation Area and the Seventy-Six Conservation Area, which stretch for about 10 miles.

[5] The area was first granted by the Spanish colonial authorities to Joseph Manning, with the first European settler in the Brazeau Bottom was George A. Hamilton, a Catholic from Maryland.

Hamilton had lived in New Madrid and received permission from Spanish authorities to settle in the Brazeau Bottom in 1797.
