CHAPALA, LAKE

Spanish Lago De Chapala, lake, west-central Mexico. It lies on the central plateau at 6,000 feet (1,800 m) above sea level in Jalisco and Michoacn states. Chapala is Mexico's largest lake, measuring approximately 48 miles (77 km) east-west by 10 miles (16 km) north-south and covering an area of 417 square miles (1,080 square km). Despite its size, the lake is very shallow and is susceptible to infestations of water hyacinth. It is fed principally by the Lerma River, which enters at the eastern end and leaves at the northeastern corner as the Santiago River. The scenic setting, pleasant climate, picturesque villages dotting the shores, and good fishing make the lake a popular resort and, increasingly in the late 20th century, a retirement centre for American citizens. Lying 30 miles (48 km) south-southeast of Guadalajara, it is easily accessible by highway, railroad, or air.
