特斯科科湖
The city of Texcoco used to be located on the shore of Lake Texcoco. This lake covered an area of 9,600 km2, but since early colonial times, floods or fears of flooding have led to various drainage projects, which over time has nearly destroyed the lake completely. Starting in the 1970s and continuing to the present day, there have been efforts to clean the polluted remnants of the lake. The remains of Lake Texcoco extend about 1,700 hectares in which aquatic birds and migratory birds from the U.S. and Canada can still be seen.
