Before 1900, the Missouri–Mississippi River system transported an estimated 400 million metric tons per year of sediment from the interior of the United States to coastal Louisiana. During the last two decades (1987–2006), this transport has averaged 145 million metric tons per year. The cause for this substantial decrease in sediment has been attributed to the trapping characteristics of dams constructed on the muddy part of the Missouri River during the 1950s. However, reexamination of more than 60 years of water- and sediment-discharge data indicates that the dams alone are not the sole cause. These dams trap about 100–150 million metric tons per year, which represent about half the decrease in sediment discharge...

Sandbars of large sand-bedded rivers of the Central U.S. serve important ecological functions to many species, including the endangered Interior Least Tern (Sternula antillarum) (ILT). ILT are colonial birds which feed on fish and nest primarily on riverine sandbars during their annual breeding season of approximately May through July, depending on region. During this time, ILT require bare sand of sufficient elevation so as not to be inundated during the period between nest initiation and fledging of hatchlings. ILT were originally listed as endangered due in part to decreases in available sandbar habitat from river channelization and impoundment. Sandbars in Central U.S. rivers used by ILT are highly dynamic,...

Abstract (from http://sp.lyellcollection.org/content/early/2015/10/09/SP408.11.abstract): We present a hierarchical series of spatially decreasing and temporally increasing models to evaluate the uncertainty in the atmosphere – ocean global climate model (AOGCM) and the regional climate model (RCM) relative to the uncertainty in the somatic growth of the endangered pallid sturgeon (Scaphirhynchus albus). For effects on fish populations of riverine ecosystems, climate output simulated by coarse-resolution AOGCMs and RCMs must be downscaled to basins to river hydrology to population response. One needs to transfer the information from these climate simulations down to the individual scale in a way that minimizes extrapolation...

These data were used to examine drivers behind changes in water temperature downriver of dams across the western U.S. from 1995-2015 and the influence of such changes on rainbow trout recruitment and rainbow and brown trout adult length. First, we linked reservoir storage capacity and dam size to the warmest monthly water temperature per water year (WY) to assess the influence of low storage capacity (shallow reservoirs) on downstream water temperature. We then took results from previously published Generalized Linear Mixed Models (GLMM) that assessed the influence of physical and biological predictors (e.g., flow, trout density, reservoir metrics) on trout recruitment and adult size and added mean annual, maximum...

Airborne electromagnetic (AEM) and magnetic survey data were collected during October 2014 in a 553-square-kilometer area that includes the East Poplar oil field on the Fort Peck Indian Reservation in northeastern Montana, USA. Data surround the city of Poplar and extend south into the Missouri River floodplain. Data were acquired with the SkyTEM301 transient electromagnetic helicopter-borne system together with a Geometrics G-822 magnetometer. The AEM average depth of investigation is about 80 m. The survey was flown at a nominal flight height of 30 m above terrain along north-south oriented flight lines; the majority of lines had a nominal spacing of 200 m with a sub-block area in the central portion of the oil...

Data were collected in June 2016 as part of a dye-trace experiment in the Missouri River downstream from Fort Peck Dam, Montana, USA. Fluorometers were deployed at 8 measurement stations over a 135-km study reach. Approximately 51 L of Rhodamine WT (RWT) dye was injected on 26 June 2016 at 14:30 MDT. The injection occured along a transect located approximately 3000 meters downstream from the confluence of the Milk and Missouri Rivers. Injection was performed via a gravity-feed system and was complete within seven minutes of initaition. RWT dye was diluted by at least half to facilitate mixing and was injected approximately 0.30 m below the water surface. Fluorometers were placed approximately 4 to 8 m from shore...
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...

In FY12, hydrogeomorphic methodology was applied along 670 miles of the Missouri River from Decatur, Nebraska to St. Louis, Missouri. In FY15, additional resources extended the HGM up river to Gavin’s Point Dam, West Yankton, South Dakota (approximate river mile 811), the location of the most downstream mainstem dam; thus encompassing the entire free flowing reach of the Missouri River and increasing the study area by approximately 800,000 acres. Using this method, engineers and ecologists incorporated state-of-the-art scientific knowledge of ecological processes and key fish and wildlife species to identify options by which to emulate natural hydrologic and vegetation/ animal community dynamics. Results of this...

Cottonwood forests are in decline becasue of losses from land use conversion and reduced regeneration from river regulation. Projecting lon-term implications of current trends and policies, or alterations of these, will help to identify the importance and scale of restoration activities needed to offset losses. This project developed a landscape dynamic model to project future (eig. 25, 50, 100 year) trends in cottonwood forst area and age distribution for four remnant floodplain reches on the Missouri River, based on recent rates (or alternative scenarios) of land use change, cottonwood recruitment, and succession. For two reaches, these changes are used to project the effects onabundances of selected songbird...

Macrhybopsis reproduction and propagule traits were studied in the laboratory using two temperature regimes and three hormone treatments and which methods produced the most spawns. Only sicklefin chub (M. meeki) spawned successfully although sturgeon chub (M. gelida) released unfertilized eggs. All temperature and hormone treatments produced M. meeki spawns, but two treatments had similar success rates at 44 and 43%, consisting of a constant daily temperature with no hormone added, or daily temperature fluctuations with hormone added to the water. Spawns consisted of multiple successful demersal circular swimming spawning embraces interspersed with circular swims without embraces. The most spawns observed for one...
