Lake Cajititlán is a shallow water body located in an endorheic basin in western Mexico at 1551 m a.s.l. The surface area is 1744 ha, maximum storage volume achieved is 70.89 Hm3, and maximum depth is 5.4 m at its maximum capacity. The lake has experienced significant changes in its level because of drought conditions in recent years. Because the lake has shallow features and is settled in a closed basin with rapid population growth, the lake water has suffered severe anthropogenic contamination causing damages in its intrinsic esthetic, social, environmental, and economic values.
