Today, Unmanned Survey Vessel (USV) carrying depth finder allows to access and record depth of locations in dangerous and polluted areas with advantages as a compact, low-cost technology. In Vietnam, USV is a new and unapplied device in practice. This paper presents the results of the experiment of measuring the depth of DenLu lake by unmanned ships named SURF20 ADCP, some near-shore random points were determined depth directly by RTK to verify. The results of depth measurements from USV were also used to establish the map in 1:1000 scale of DenLu lake bottom.
