Abstract Data for 25 morphometrical parameters describing the geomorphology of Lake Patzcuaro, Michoacan, Mexico have been derived from an up-to-date bathymeric map with contour-lines at 1.0 m intervals. Maximum depths were observed in the northern part of the lake whereas considerable shallow areas are developing in the south. Insulosity is continuously modified due to certain areas becoming part of the mainland and the appearance of new islands with increasing shallowness and man-made channels. The hydrographic survey was evaluated using the optimization model suggested by Hakanson (1978). An information value of 0.788 for 12 contour lines in the new bathymetric map is reported. The usefulness of accurate morphometrical data in process-orientated modelling for lake management is discussed.
