Shapefile created by USGS. Channel transects were constructed to be used in evaluating channel widths and channel width variation. Transects were laid out at 0.1 mile intervals along the navigation channel thalweg. They extend perpendicular to thalweg and intersect the bankfull channel margin, delineated from low-altitude aerial orthophotos provided by the US Army Corps of Engineers, 11/1/2012 to 11/21/2012. The bankfull dimensions were digitized by hand. Each transect was additionally attributed with the USGS bend number, Pallid Sturgeon Population Assessment Program (PSPAP) segment number, and PSPAP bend number.

Shapefile created by USGS. This is a polygon created from Landsat TM imagery. All Landsat 4-5 TM images overlapping the Missouri River downstream from Gavins Point Dam were identified and examined for lack of clouds. Usable images were classified into sand, vegetation, and water. Classified images were then merged, and the number of times a given pixel was classified as either sand, vegetation, or water were computed. The presented dataset represents pixels which were classified as sand in greater than 5% of images which were collected during a growing season defined as julian day 116-296 (to preclude vegetated islands, which classify as sand outside of foliation), translated into polygons.

Shapefile created by USGS. This is a channel polygon coverage with USGS-delineated bends, each attributed with rive mile (location along river), bend area, thalweg sinuosity, mean channel width, standard deviation of channel width, number of navigation structures per kilometer of channel, total length of navigation structures per kilometer of channel, area of persistent sand, and catch per unit effort of age-0 Scaphirhynchus sturgeon. Each bend is also attributed with statistically determined cluster assignment according to 3-, 4-, and 6-cluster k-means clustering.

Shapefile created by USGS by generating a centerline between the banks of the Lower Missouri River and identifying inflections in the centerline. Inflections were used to automatically define upstream and downstream limits of the bend. Lateral limits of bends were extended to encompass all of the high banks of the river. The centerline was identified using the river miles of the U.S.Army Corps of Engineers as defined in 1960.

Shapefile created by USGS. This is an updated mapping and classification of navigation structures on the Lower Missouri River. The process used high-resolution aerial photography acquired by the U.S. Army Corps of Engineers duirng November 2012. Naivigation structures were classified into 8 categories and attributed with lengths. Each structure was also attributed with adjacent channel width and constricted width.

Shapefile created by USGS. This is a channel polygon coverage digitized from aerial photography at the top of the high bank. The low-altitude aerial orthophotos were provided by the US Army Corps of Engineers and were acquired 11/1/2012 to 11/21/2012 under leaves off and relatively low-water conditions. Notably, these conditions post-date 2011 flooding and channel changes. The features digitized correspond to the interpreted high bank, or bankfull conditions. Types of channel polygons were also discriminated: main channel, side channel chutes, islands, backwaters, and irregular off-channel aquatic features.
