River of Sand – The Bottom of the Big Muddy

Presentation by Carrie Elliott, U.S. Geological Survey River Studies

USGS Geologist Carrie Elliott will share what her research has revealed about the hidden world of the bottom of the Missouri River, what she learned during the Great Flood of 2019 and share images of this murky and shifting environment.

When you look at the surface of the Big Muddy do you wonder about what is going on below?  Let’s explore what the U.S. Geological Survey has been learning about what is happening on the bottom of the Missouri River.

The riverbed is dynamic and changes as flows go up and down. Carrie Elliott and her colleagues at the USGS have been surveying the Missouri River to help understand pallid sturgeon habitat since 2008. They have mapped moving sand dunes, deep holes, trees, and rocky outcrops on the bottom of the river. Carrie will share some of the insights they’ve found about the bottom of the Big Muddy.

During the flood of 2019 they mapped the same 2-mile long reach of the Missouri River near Lexington, Missouri nine times and found some interesting changes in the sand dunes on the river bed over the course of the flood event. There was a lot of water, and it was moving faster than usual, but the biggest challenge in mapping during the flood last summer during the flood was finding an accessible boat ramp. In addition to highlighting some of the flood work, Carrie will share some interesting maps from a few sites you might recognize around Boone County.

Carrie Elliott has worked on Missouri River habitat dynamics for the U.S. Geological Survey at the Columbia Environmental Research Center since 2002.  She has a master’s degree from Utah State University and her work with the River Studies Branch has addressed physical habitat on large rivers at multiple spatial scales using a variety field, GIS, and remote-sensing tools.  She has worked closely with biologists on a variety of interdisciplinary projects related to river corridor habitats and geomorphology from hydroacoustic mapping to landscape-scale habitat classification.
