Rio Grande, Boquillas Canyon: Rio Grande Village to Heath Canyon (34 miles)

Recreation & Access

Launching at Rio Grande Village is routine for Boquillas paddling trips. Always tie up your boats overnight because you just never know when a pulse flow from upstream rains might come. But more likely, extremely high winds can blow away boats and tents. It happens!

Historical/Cultural Significance

Conflict with Mexico continued when the United States annexed Texas as a state in 1845. Mexico claimed that the new border between Texas and Mexico was the Nueces River, while the United States contested the border was the Rio Grande. The Treaty of Guadalupe Hidalgo, that brought an official end to the Mexican-American War (1846-1848), was signed on February 2, 1848, at Guadalupe Hidalgo, where the Mexican government had fled with the advance of U.S. forces. By its terms, Mexico ceded 55 percent of its territory, including parts of present-day Arizona, California, New Mexico, Texas, Colorado, Nevada, and Utah, to the United States. Mexico relinquished all claims to Texas, and recognized the Rio Grande as the southern boundary with the United States. The United States paid Mexico $15,000,000 “in consideration of the extension acquired by the boundaries of the United States” (see Article XII of the treaty) and agreed to pay American citizens debts owed to them by the Mexican government. The treaty gave rise to development of the IBWC International Boundary and Water Commission which governs all concerns of flow and sharing of the boundary waters of the Rio Grande and other boundary waters of New Mexico, Arizona and California.
