Within large-river ecosystems, floodplains serve a variety of important ecological functions. A recent survey of 80 managers of floodplain conservation lands along the Upper and Middle Mississippi and Lower Missouri Rivers in the central United States found that the most critical information needed to improve floodplain management centered on metrics for characterizing depth, extent, frequency, duration, and timing of inundation. These metrics can be delivered to managers efficiently through cloud-based interactive maps. To calculate these metrics, we interpolated an existing one-dimensional HEC-RAS hydraulic model for the Middle Mississippi River, which simulated water surface elevations at cross sections spaced...

The Southeastern U.S. spans broad ranges of physiographic settings and contains a wide variety of aquatic systems that provide habitat for hundreds of endemic aquatic species that pose interesting challenges and opportunities for managers of aquatic resources, particularly in the face of climate change. For example, the Southeast contains the southernmost populations of the eastern brook trout and other cold-water dependent species. Climate change is predicted to increase temperatures in the South and is likely to have a substantial effect on extant populations of cold-water biota. Thus, aquatic managers are tasked with developing strategies for preserving cold-water dependent biota, such as eastern brook trout,...

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.
Pebble counts were performed to assess the bed surface grain size distribution at different habitats within a reach of the Big River near Washington State Park, Missouri. These data were collected in support of research assessing the hydraulic conditions of freshwater mussel habitat in the Big River. One component of this investigation was to examine the theoretical stability and instability of sediment particle sizes that are present within mussel habitats as well as within nearby reference habitats. These pebble counts furnished grain size data used for reference sediment stability predictions. Pebble counts were performed at seven different habitats in a study reach on the Big River following the methods of Wolman...

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.

Recent extreme floods on the Mississippi and Missouri Rivers have motivated expansion of floodplain conservation lands. Within Missouri there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly as future climatic conditions may be highly variable. These lands have the potential to provide valuable ecosystem services like provision of habitat, nutrient processing, carbon sequestration, and flood-water storage that produce economic values in terms of recreational spending, improved water quality, and decreased flood hazards. However, floodplain managers may need tools to help them understand nonstationary conditions...

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 child data release includes RGB (red-green-blue) videos acquired from an Unmanned Aircraft System (UAS) 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....

Pebble counts were performed to assess the bed surface grain size distribution at five delineated mussel habitats in the Big River, Missouri. These data were collected in support of research assessing the mussel communities and characteristics of freshwater mussel habitats in the Big River (Albers and others, 2016; Roberts and others, 2016). Pebble counts were performed at the mussel habitats following the methods of Wolman (1954). Grain diameters of 99-100 particles were measured on the intermediate axis. The pebble count data are semi-continuous; grains smaller than 2 mm were classified as sand, and grains larger than 64 mm were classified as either cobble (65-256 mm) or boulder (greater than 256 mm) but measured...

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.
Water-surface elevation measurements were performed for a range of flow events up to bankfull discharge within four reaches of the Big River, Missouri. The study reaches are Site W (STW), Rockford Beach (RFB), Phelps Bend (PHB), and Washington State Park (WSP). The water-surface elevation measurements were collected to provide hydraulic model calibration data in support of research assessing the hydraulic conditions of freshwater mussel habitat in the Big River. Data were collected either manually or by boat in the study reaches using a Global Navigation Satellite System (GNSS) receiver. Calibration data also included water-surface elevation data from bathymetry and terrestrial lidar surveys. Models were calibrated...
