Over many years Lake Chapala has suffered severe water loss. In the past, the lake’s volume was twice the size of Lake Constance. It has lost about three-quarters of its volume. From villages which once were located at the edge of the lake, you can hardly see the lake today. Irresponsible use of water, corruption and a profit seeking mentality have almost completely destroyed this drinking water reservoir for 6 million people. A huge dam project is planned to provide water for the people who depend on Lake Chapala as drinking water reservoir. This project is economically absurd, unsocial and an ecological disaster. Some 3,000 local fishermen are threatened with commercial ruin, fish species such as "popoche" which used to be very common is almost extinct due to lack of water and DDT presence in the water.
