| Abstract: | project is being proposed to expand and enhance previously constructed shallow-water habitat (SWH) along the Missouri River at Glovers Point Bend in Thurston County, Nebraska. The U.S. Army Corps of Engineers (USACE) is constructing SWH along the lower Missouri River downstream of Gavins Point Dam to mitigate aquatic habitat lost from past bank stabilization and channelization. Increasing SWH will enhance habitat for the endangered pallid sturgeon (Scaphirhynchus albus) population along the lower Missouri River. The District is referring to the proposed project as the Glovers Point project. Deposited sediment will be excavated from the area to enhance and expand previously constructed SWH at the project site. Sediment excavation will involve hydraulic dredging with the dredge spoil being discharged to the adjacent Missouri River. It is believed the dredge material will be primarily sand with some silts and clays. An estimated 910,000 cubic yards of material would be excavated and discharged to the Missouri River. The intent of this report is to provide Factual Determinations of the potential water quality impacts of hydraulic dredging discharge at the proposed Glovers Point project on the Missouri River. As defined in the Federal CWA and USACE Regulation No. 1110-2-8154, water quality is defined as the physical, chemical, and biological characteristics of water. |
