Lagoons and Aguamilpa Dam Reservoir, Mexico
Various lagoons filled with dark brown and green water can be noted along the western coast of Mexico. The largest lagoon, just below the center, is the Agua Brava Lagoon.
Moving up the coast, the dark curvy line of a river connects the Agua Grande Lagoon to the Pacific Ocean. Continuing northwestward, the El Caimanero Lagoon can be seen near the edge of the image.
Further inland, east of the Agua Brava Lagoon, is a large reservoir whose waters appear green. This reservoir, which covers a large part of the territory of the municipality of El Nayar in Nayarit, was created by the Aguamilpa Dam on the Río Grande de Santiago, built in 1997.
The river descends from the reservoir to the coastal lowlands, passing by Santiago Ixcuintla and empties into the Pacific Ocean 16 km northwest of San Blas, in Nayarit. A small amount of sediments can be seen flowing forth from its mouth.
