Book excerpt: Excerpt from The Effects of Barge Traffic on Suspended Sediment and Turbidity in the Illinois River: For United States Fish and Wildlife Service, Rock Island Field Office Ecological Services 1830 Second Avenue, Rock Island, Illinois 61201 Prepared December 3, 1980 Starrett (1971 and 1972), Sparks and Starrett (1975), and Johnson (1976) have reported that passage of a commercial tow (several barges lashed together with cables and pushed by a diesel-powered boat) on the Illinois River can increase the turbidity of the water by 100-200 Jackson Turbidity Units (JTU) and that it takes up to 21/2 hours for the turbidity to return to background levels following passage of the tow. Karaki and vanHoften (1974) described, on the basis of hydraulic theory, the types of waves and turbulence generated by commercial and recreational boats, and presented infrared aerial photographs of turbidity plumes generated by tows and near-shore turbidity generated by fast-moving recreational boats. Although the temporary resuspension of bottom sediments by tows and recreational boats has been well documented, no one has determined whether boats contribute significantly to the so-called "background" or "ambient" turbidity and suspended sediment levels in navigable rivers. The issue of whether or not boat traffic contributes to suspended sediment is important from both environmental and economic points of view. Sediment affects aquatic life by impairing such vital biological functions as photosynthesis, respiration, feeding, growth, and reproduction. For example, suspended sediment reduces light penetration, which in turn depresses photosynthesis in submerged aquatic plants. The ability of game fish to see their prey and their mates is also diminished by turbid water. People generally consider turbid water to be less esthetically pleasing than clear water, and it is difficult for a water skier or swimmer to see underwater obstructions in turbid water. State and federal pollution control agencies are continuing to spend millions of dollars in controlling suspended solids from both point and nonpoint sources. These efforts may be negated in navigable rivers if boats are contributing significantly to suspended sediment and turbidity levels.

Book Restoration of Aquatic Ecosystems

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
