(UMRB) is a major sub-basin of the entire Mississippi River, one of the largest and most diverse ecosystems in North America. The length of the Upper Mississippi River (UMR) is approximately 800 miles (1,287 km). The drainage area of the basin is approximately 189,189 square miles (489,980 km2) and contains about 15 percent of the drainage area of the entire Mississippi River Basin. The Basin i...
متن کاملSwimming performance of adult bighead carp Hypophthalmichthys nobilis (Richardson, 1845) and silver carp H.molitrix (Valenciennes, 1844)
Although the movement of invasive bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix) in the Upper Mississippi River system is dependent on their ability to swim through its numerous lockanddams, the swimming performance of adults of these species is at present unknown. Using a large (2,935L) mobile swim tunnel, the swimming performance of adult bighead and adult silver carp...

متن کاملSpatial and temporal variation in suspended sediment, organic matter, and turbidity in a Minnesota prairie river: implications for TMDLs.
The Minnesota River Basin (MRB), situated in the prairie pothole region of the Upper Midwest, contributes excessive sediment and nutrient loads to the Upper Mississippi River. Over 330 stream channels in the MRB are listed as impaired by the Minnesota Pollution Control Agency, with turbidity levels exceeding water quality standards in much of the basin. Addressing turbidity impairment requires ...
