Lake Travis Multibeam and Sidescan
Lake Travis, Texas
An engineering firm contracted us to conduct RTK multibeam bathymetric and side scan sonar surveys of three locations within Lake Travis, Texas. Lake Travis is the main reservoir feeding the Austin, TX area and is located in the Hill Country of Texas at an elevation of roughly 700 ft. NAVD 88. The purpose of the survey was to locate the 655 ft. contour on the lakebed for designing a new water intake valve to feed nearby towns, like Volente, Texas.
