Mapas batimétricos y parámetros morfométricos de lagos patagónicos de Neuquén, de Río Negro y del Chubut (Argentina)

A limnological and fish survey program was developed on 112 lakes and reservoirs of Argentina during the summers of 1984 to 1987. Bathymetric surveys with a SIMRAD Skipper 411 model echosounder and line and lead were conducted on more than 40 lakes. This report presents bathymetric maps for seventeen lakes and reservoirs situated in Patagonian Andes Region and Patagonian Plateau betweem 38°53'S and 45°30'S. The bathymetric maps for two reservoirs were made from topographic maps before impoundment. Hypsographic and depth-area curves, and some morphometric parameters are presented for twenty one Patagonian lakes. Mean depth ranged from 2.0 to 111 m. The deepest lakes are situated in Patagonian Andes Region. Colhue Huapi Lake on Patagonian Plateau, is very shallow, having a mean depth of 2.0 m and being 810 km. in surface area.
