GIS Surveyors used the CEE LINE echo sounder combined with a Trimble R10 RTK GNSS and Trimble TSC3 data collector to complete a bathymetric survey of Lake Eleanor. Located north of Los Angeles near Thousand Oaks at about 1000ft elevation the small lake survey was best conducted from a kayak. Using a trolling motor to minimize the kayak roll movement, Chief of Parties, Gavin McKellar was able to effectively and quickly complete the job.
