Agricultural runoff is a major non-point source pollutant and is the leading impairment of streams and rivers in the USA. This study examined the effects of agricultural, forest and urban land cover on water quality at the watershed level. Forty-three catchments ranging from 12 to 50 km2 were selected based on a land cover gradient within Lower Kaskaskia River Watershed in Illinois. Grab samples were collected and analyzed for nutrients, bacteria, and total suspended solids (TSS). Forest land cover was included in six of the ten regression models produced. Four of these regression models were for base flow conditions, suggesting that forest land cover had a significant impact on base flow water quality. Urban land...

Background materials were compiled to determine what is currently known about barge fleeting on the Upper Mississippi River System. Background materials included available literature, contacts with professionals, permit information, regulatory statutes and a review of current aerial photography. Field investigations were conducted in an attempt to examine most of the fleeting areas on the Upper Mississippi and the Illinois rivers. Method of anchoring barges, distance to shore, water depths, substrate and shoreline composition, erosion, and any tree damage were noted. Fleeting areas were all located close to terminals. Barges were moored as close to the shore as water depths permitted. Trees were most often used...
