Abstract
The objective of this investigation 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 that removed all reverberative energy and left no primary reflections. To predict the phenomena prior to conducting the survey would have required extensive seismic experimentation. Although the main objective was not achieved, possible solutions to overcome water bottom multiples generated in this environment are presented in the recommendations section of this report.
