Texcoco Lake is a large, shallow lake located in the Valley of Mexico, near the city of Mexico City. Historically, it was part of a larger system of lakes that included Lake Xochimilco and Lake Chalco. The lake played a significant role in the development of the ancient Aztec civilization, serving as a vital resource for fishing and agriculture. Today, Texcoco Lake is mostly dry due to extensive drainage and urban development. Efforts are being made to restore parts of the lake and its surrounding wetlands, which are important for local biodiversity and water management. The area is also significant for its archaeological sites related to the Aztecs.
