The Rio Grande in the United States or the Río Bravo in Mexico, also known as P’osoge in Tewa and Tó Ba’áadi in Navajo, is one of the principal rivers in the Southwestern United States and in northern Mexico. The length of the Rio Grande is 1,896 miles (3,051 km), making it the 4th longest river in the United States and in North America by main stem. It originates in south-central Colorado, in the United States, and flows to the Gulf of Mexico. The Rio Grande drainage basin (watershed) has an area of 182,200 square miles (472,000 km2); however, the endorheic basins that are adjacent to and within the greater drainage basin of the Rio Grande increase the total drainage-basin area to 336,000 square miles (870,000 km2).
The Nueces River is a river in the U.S. state of Texas, about 315 miles (507 km) long. It drains a region in central and southern Texas southeastward into the Gulf of Mexico.

Its mouth is now on the western edge of that reservoir at the mouth of Monticello Canyon.
