Information to be Derived:

Summary of Activity and Data Gathered: Completed sidescan mosaic of reservoir. Approx. 30 km of sub-bottom collected before davit failed; fish lost, recovered 3 days later! Samples collected at 21 sites, most with good video and still photos. Sidescan sonar; Sub-bottom: 15 lines, 30 km; Samples.
