The Bureau of Mines and the U.S. Geological Survey conducted a joint overwater seismic study at Rend Lake, Illinois, in the fall of 1980. The objective was to map fault trends adjacent to underground coal mine workings overlain by a shallow body of water. The nature of the lake bottom was found to act as a wave guide and reverberative mechanism so that water bottom multiples obscured all reflections from depth. This occurrence was proved by the application of extensive computer modeling programs to the data, which removed all reverberative energy and left no primary reflections.
