Backwaters and other floodplain waterbodies are rare within the Middle Mississippi River. The lack of these habitats likely influences water quality, nutrient processing, and communities of organisms. In early 2016 a major flood event breached two levees south of Cape Girardeau, MO resulting in the creation of two new backwaters. Water quality, metabolic rate, and fish community data were collected from the new backwaters as well as an isolated floodplain lake.

Off-channel and floodplain water bodies are important components of large river ecosystems. These habitats often take the form of side channels, backwaters, and floodplain lakes formed by meander cut-offs or extreme high flow events and can be permanently connected to the main river but may become disconnected during low flow periods. High water in 2016 created some rare back waters in the Mississippi River the data was collected to understand these new back waters in the Middle Mississippi River.
