Levee Integrity Surveys Stockton and Lodi, California
Our 24' vessel, the M/V Royal Fish, was equipped with a Reson 8125 multibeam sonar that was tilted 45 degrees and an Edgetech DF1000 sidescan sonar. The goal of the survey was to provide as much information as possible about the subaqueous condition of the levees.
The project was very successful and provided the engineers with several areas that were undercut, or lacked rip-rap. Other items of interest included three vehicles found underwater near the I-5 Bridge.
