Abstract : The objective of the geophysical investigation is to determine the depth to and elevation of the underlying rock units upstream and downstream of each lock and dam structure. The results are intended to supplement previously obtained soil borings by providing continuous profile line coverage of the rock surface throughout each project area and aid in placement of additional borings. The interpreted seismic data will also provide better descriptions of variations in subbottom conditions. Two high resolution subbottom profiling systems were used to meet the primary objectives of the investigation.
