Book excerpt: About 2,250 square kilometers of the Lake Erie bottom between Conneaut and Toledo, about 25 percent of Ohio's open lake part of Lake Erie, was surveyed to assess potential sand and gravel resources. Primary survey data consist of 690 kilometers of high-resolution seismic reflection profiles between Conneaut and Toledo; 58 vibracores with a maximum length of 6.1 meters were also taken between Conneaut and Marblehead, Ohio. Survey limits were generally from the -7.5-meter depth contour to about the -14-meter depth contour, a maximum of about 16 kilometers offshore. The objectives of this survey were to acquire additional information, primarily subbottom data from known sand deposits along the south shore of Lake Erie, and to investigate the areas between the known sand deposits for undiscovered sand and gravel resources. Sizable sand deposits of more than 10 million cubic meters exist at four areas. Sand in two of the areas, Fairport Harbor and Lorain-Vermilion, has the highest potential for beach restoration projects. Cores taken outside of the sand deposit areas generally contain modern lacustrine mud or silt at the surface except in areas where till is exposed. A few cores contained sand at depth but the overlying fine-grained sediment and the lack of areal continuity make them undesirable as sand deposits for beach restoration and nourishment.
