Nutrient Contributions From Alluvial Soils Associated With The Restoration Of Shallow Water Habitat In The Lower Missouri River, D C. Heimann, D M. Morris, T R. Gemeinhardt

United States Geological Survey: Staff Publications

The Missouri River has been extensively altered as the result of channelization, bank stabilization, and the construction of six main stem reservoirs. In response to the resultant habitat loss, the US Army Corps of Engineers was tasked with restoring approximately 8100 ha of shallow water habitat (SWH), in part, for the benefit of the endangered pallid sturgeon (Scaphirhynchus albus). Construction of off-channel habitats involves the removal and disposal of excavated alluvium either by direct discharge into the river or by secondary erosion, which raised concerns regarding the introduction of sediment and associated nutrients into the Missouri River. Soils from nine …
