This book was released on 1981 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The approach taken in the present study was to select two sites in proximity that would also be representative of the area subjected to the perturbation cause by dredging operations. One site would serve as the control site and not be dredged; the second would be the experimental site and would be dredged in a manner approximating normal operations. Each site would be sampled in a quantitative manner both before and after dredging on a logarithmic time scale for the first year and on a quarterly basis thereafter. Ideally, the two sites would be located somewhere in the mid-lake region and would not ever have been dredged. Unfortunately, because dredging operations have occurred pretty much at random over the past 45 years with few, if any, records having been kept, it was virtually impossible to ascertain that any particular area had never been dredged. The next best alternative was to select an area that had not been dredged recently and that would be protected from being dredged again before the completion of the study. Such an area that had not been dredged recently and that would be protected from being dredged again before the completion of the study. Such an area exists along a two-mile wide swath, one mile on each side of the Lake Pontchartrain Causeway, which was first open in 1956.

This book was released on 1987 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: This final environmental impact statement assesses the impacts of clam shell dredging in Lakes Pontchartrain and Maurepas, Louisiana as permitted under 5-year permits issued in 1982 that will expire in December 1987. The document also assesses the impacts of proposed 10-year permit extensions that would allow shell dredging to continue under the same conditions. Clam shells (Rangia) have been harvested from the lakes area since 1933 by means of hydraulic dredges. The shells are used primarily in construction activities, but have a variety of other uses as well. There has been considerable controversy over the environmental impacts of shell dredging. This FEIS assesses impacts to the lakes area with and without shell dredging under existing and future conditions. Numerous alternatives are discussed and evaluated in the FEIS and two have been discussed in detail. Keywords: Water quality; Endangered species; Biological/cultural effects; Economic impact; Ecology/recreation; Lake water pollution. (EDC).

Available in PDF, EPUB and Kindle. Book excerpt: A vital and volatile part of the New Orleans landscape and lifestyle, the Lake Pontchartrain Basin actually contains three major bodies of water—Lakes Borgne, Pontchartrain, and Maurepas. These make up the Pontchartrain estuary. Robert W. Hastings provides a thorough examination of the historical and environmental research on the basin, with emphasis on its environmental degradation and the efforts to restore and protect this estuarine system. He also explores the current biological condition of the lakes. Hastings begins with the geological formation of the lakes and the relationship between Native Americans and the water they referred to as Okwa'ta, the “wide water.” From the historical period, he describes the forays of French explorer Pierre Le Moyne D'Iberville in 1699 and traces the environmental history of the basin through the development of the New Orleans metropolitan area. Using the lakes for transportation and then recreation, the surrounding population burgeoned, and this growth resulted in severe water pollution and other environmental problems. In the 1980s, the Lake Pontchartrain Basin Foundation led a concerted drive to restore the lakes, an ongoing effort that has proved significant.
