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 Lower Missouri River, which simulated water surface elevations at cross sections spaced (<1...

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 the inputs and outputs from the development of Escherichia coli (E. coli) concentration models for the four Missouri River sites near Omaha, Nebraska. Model development, models, and results are published in the associated U.S. Geological Survey (USGS) report Densmore and others, 2020. Load Estimator models (LOADEST) (Runkel and others, 2004) were developed from the first 5 years of data (July 2012–September 2016). Sites include Missouri River at NP Dodge Park at Omaha, Nebr. (USGS Site ID 412126095565201), Missouri River at Freedom Park Omaha, Nebr. (USGS Site ID 411636095535104), Missouri River near Council Bluffs, Iowa (USGS Site ID 06610505), and Missouri River near La Platte, Nebr....
