Here we report on an advanced survey system that combines multibeam echo sounding with underwater photography, which was used to collect accurate data on the distribution and abundance of submerged aquatic vegetation (SAV) in Lake Towada. The use of this system enabled us to visualize the cover, height, and biomass of the SAV over the lake bottom, as well as to distinguish between different components of the SAV such as vascular and algal plants. The spatial distributions of these major components of the SAV varied as a function of the depth gradient. The vascular component was mostly represented by Potamogeton species, which accounted for around one-third of the standing mass of SAV, whilst more than half of the SAV was algal (charophytes). This abundance of charophytes may well be responsible for the high water quality and transparency of Lake Towada.
