Book excerpt: This study was designed to investigate the environmental effects of disposal of material from maintenance dredging on the aquatic habitat around Island 117, Pool 8, Upper Mississippi River. Dredging impacts of disposal of dredged material in the past have included the conversion of productive aquatic and semiaquatic habitat to sandy shoals and islands, as well as the impairment of backwater circulation. Disposal activity at Island 117 during 1974 produced no measurable effect on those variables considered. The reasons for the negligible impact may have been as follows: (1) a relatively small amount of material was deposited at the site in 1974 (11,144 cu yds compared to a 19-year average job size of 65,500 cu yds); (2) dredged material was not allowed to pass over the crest of Island 117 into backwater areas as it had in past years because of court-ordered dredged material placement limitations imposed by the State of Wisconsin; and (3) the variance of the baseline data, caused by annual, seasonal, and diel fluctuations, was significant for most variables. If 1974 disposal activities affected water quality in the study area, these effects were masked by the natural background variation in the variables considered. Turbidity and nitrite-nitrogen, which were increased by disposal of dredged material in 1973, were not significantly altered during 1974.

This book was released on 1981 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
