Summary of Activity and Data Gathered: Covered 331 square kilometers of Lake Powell UT/AZ using the R/V Stephens (23' SeaArk) owned by Utah Water Science Center, in Salt Lake, City. Collected bathymetry and backscatter data along 2407 kilometers of lines using a Dual-head Reson T20-P. Collected 92 kms of EdgeTech 424 data in the northeast portions of the lake at confluence of Colorado and San Juan Rivers.
