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.

This dataset includes measurements of flow, turbulence, and bathymetry generated from multibeam bathymetry for a short reach of the Missouri River at Searcys Bend (SB) near Huntsdale, Missouri. Flow and turbulence were characterized using a Signature 1000 mounted on an anchored moving boat and an Aquadopp mounted on a tripod near the bed. Repeat bathymetric measurements were made in small patches to characterize bedform movement during velocimetric instrument deployment. The mean daily discharge at the U.S. Geological Survey Streamflow gaging station 06909000 fifteen miles upstream at Boonville, Missouri on September 16, 2021 was 1,291 cubic meters per second.
Lack of reproduction has been hypothesized to be a factor in the decline of the pallid sturgeon (Scaphirhynchus albus) through much of its range. Spawning habitat and behavior have only recently been documented on the Lower Missouri River, which comprises over 1,300 river kilometers of undammed river. This data consists of habitat measurements for ten pallid sturgeon spawning events from 2008-2013 that occurred in discrete reaches dispersed over hundreds of kilometers on the Lower Missouri River.
This data release contains river bed surface grain size measurements, water-surface elevation measurements, and digital elevation models (DEMs) for select reaches of the Big River, Missouri. These data were collected in support of research assessing the hydraulic conditions of freshwater mussel habitat in the Big River. The individual metadata associated with each data type describe the process steps, data inputs and sources, and the locations where the data were collected.
This dataset consists of seven geomorphic variables attributed to standard river mile address points at 0.1 mile (160 m) intervals between Fort Peck Dam and the headwaters of Lake Sakakawea. The data illustrate the geomorphic variation in this 300-km segment of the Upper Missouri River and are indicative of channel complexity, thought to be an important influence on dispersal and retention of larval sturgeon.

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.

This child data release includes fluorometer measurements of Rhodamine WT dye concentration and turbidity acquired during a tracer experiment performed on the Missouri River near Columbia, Missouri, on May 5, 2021. One of the primary goals of this tracer experiment was to assess the feasibility of inferring concentrations of a visible dye (Rhodamine WT) from various types of remotely sensed data in a large, highly turbid natural river channel. Previous research on remote sensing of tracer dye concentrations has focused on clear-flowing streams, but the Missouri River is much more turbid. As a result, the effect of the dye on the reflectance of the water could be obscured by the effects of suspended sediment on reflectance....

This is a shapefile of points summarizing inundation metrics and geomorphic variables for bends in the downstream-most 800 km of the Lower Missouri River. Points are located at the centroids of 10-km bends of the river. The metrics were developed through analysis of inundation maps calculated from a 1-dimensional hydraulic model for the channel and floodplain. Water-surface elevations were extended across the valley bottom and intersected with lidar-derived floodplain topography to calculate inundation depth and extent on a daily basis. Detailed methods are documented in Bulliner and others (2017). We evaluated longitudinal spatial variation by aggregating floodplain inundation estimates by Thiessen polygons centered...

This dataset is part of a multi-scale assessment and classification for segments of 15 rivers of the Upper Midwest United States that meet various criteria for largeness. All rivers are tributary to the Mississippi River system. The 11,600 kilometers (km) that qualified as large were parsed into 10-kilometer-long segments and classified by major alterations (free-flowing, navigation pools, storage reservoir). The dataset also includes a statistically based, component classification based on the 10-km segments. Cluster analysis of hydrologic variables from 66 streamflow gaging stations yielded 5 clusters calculated from 5 ecohydrological metrics related to lateral connectivity with the floodplain. A separate cluster...

Management actions intended to increase growth and survival of pallid sturgeon (Scaphirhynchus albus) age-0 larvae on the Lower Missouri River require a comprehensive understanding of the geomorphic habitat template of the river. The datasets described here are intended to support decisions relating to where channel-reconfiguration projects should be located to optimize effectiveness of interception rearing complexes (IRCs). The bend-scale geomorphic classification of the Lower Missouri River is intended to help in the design of monitoring and evaluation of IRC projects. The bend-scale classification was based on geomorphic and engineering variables for 257 bends from Sioux City, Iowa to the confluence with the...

This dataset includes 3 velocity measurements in 3 locations collected with a Nortek Aquadopp mounted near the bed of the Missouri River in three different locations at Searcys Bend (SB) near Huntsdale, Missouri. The measurements contain near-bed measurements of water velocity. The discharge at the U.S. Geological Survey Streamflow gaging station 06909000 fifteen miles upstream at Boonville, Missouri on September 16, 2021 was 1,291 cubic meters per second.
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.
