Book Description
Large river systems are valuable national resources that provide numerous benefits to travel, shipping, recreation, and fish and wildlife. However, efforts to expand one of the uses frequently come in direct conflict with one or more of the othersThis guide attempts to bring together all scientific data that are available on techniques that have been or can be used to offset or reduce the impacts of development and maintenance of Upper Mississippi River System or other large river systems. Decision makers are thus provided an objective descriptin of options now at their disposal when they attempt to weigh the merits of defects associated with a particular action.

An Assessment of Water Quality Impacts of Maintenance Dredging on the Upper Mississippi River in 1979

Book Description
In connection with the 1979 maintenance dredging season, the Corps of Engineers, St. Paul District, investigated the water quality impacts of hydraulic and clamshell dredging operations at five selected sites on the Upper Mississippi River. Turbidity values and suspended solids were monitored at all sites, and selected chemical parameters were monitored at two hydraulic dredging sites. At most sites, dredging and disposal operations produced minor and localized changes in water quality. No statistically significant increases in chemical parameters were noted due to hydraulic dredging operations. However, effluents from the disposal area did cause some elevations of heavy metals (cadmium, lead, nickel, zinc, copper, chromium) and total ammonia. None of the chemical parameters tested exceeded their maximum permissible level proposed by Federal Water Quality Criteria. The five monitoring studies generally indicated that rapid settling and dilution occurred near and downstream of dredging and disposal operations.
