The Rio Grande's water moves from Colorado to the Gulf of Mexico. Every year during spring, melted snow would flow into the Rio Grande, bringing seasonal flood waters to the most southern tip of Texas. [3] Given the overflow of the river's main and distributary channel banks, the Rio Grande would carve new river channels, known as resacas. When the seasonal flooding ended and the river retreated, the newly formed oxbow lakes remained, creating resacas all throughout the Rio Grande Valley. [3]
There are two explanations for the origin of the word resaca. The first explanation holds that it is a contraction of the Spanish phrase rio seco (dry river). The second explanation is that the word stems from the Spanish word resacar (to retake). The latter is the most plausible explanation given that the primary geological function of a resaca is to divert and dissipate floodwater from the river. [2]
The word resaca is a regionalism. Elsewhere, these are referred to as oxbow lakes.
The Battle of Resaca de la Palma was one of the early engagements of the Mexican–American War, where the United States Army under General Zachary Taylor engaged the retreating forces of the Mexican Ejército del Norte under General Mariano Arista on May 9, 1846. The United States emerged victorious and forced the Mexicans out of Texas.
The Thornton Affair, also known as the Thornton Skirmish, Thornton's Defeat, or Rancho Carricitos, was a battle in 1846 between the military forces of the United States and Mexico 20 miles (32 km) west upriver from Zachary Taylor's camp along the Rio Grande. The much larger Mexican force defeated the Americans in the opening of hostilities, and was the primary justification for U.S. President James K. Polk's call to Congress to declare war.
An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. It takes its name from an oxbow which is part of a harness for oxen to pull a plough or cart.
The Lower Rio Grande Valley, commonly known as the Rio Grande Valley or locally as the Valley or RGV, is a region spanning the border of Texas and Mexico located in a floodplain of the Rio Grande near its mouth. The region includes the southernmost tip of South Texas and a portion of northern Tamaulipas, Mexico. It consists of the Brownsville, Harlingen, Weslaco, Donna, Pharr, McAllen, Edinburg, Mission, San Juan, and Rio Grande City metropolitan areas in the United States and the Matamoros, Río Bravo, and Reynosa metropolitan areas in Mexico. The area is generally bilingual in English and Spanish, with a fair amount of Spanglish due to the region's diverse history and transborder agglomerations. It is home to some of the poorest cities in the nation, as well as many unincorporated, persistent poverty communities called colonias. A large seasonal influx occurs of "winter Texans" — people who come down from the north for the winter and then return north before summer arrives.
The Rio Hondo is a tributary of the Los Angeles River in Los Angeles County, California, approximately 16.4 miles (26.4 km) long. As a named river, it begins in Irwindale and flows southwest to its confluence in South Gate, passing through several cities. Above Irwindale, its main stem is known as Santa Anita Creek, which extends to another 10 miles (16 km) northwards into the San Gabriel Mountains where the source, or headwaters, of the river are found.
South Texas is a geographic and cultural region of the U.S. state of Texas that lies roughly south of—and includes—San Antonio. The southern and western boundary is the Rio Grande, and to the east it is the Gulf of Mexico. The population of this region is more than 5 million according to the 2024 census estimates. The southern portion of this region is often referred to as the Rio Grande Valley. The eastern portion along the Gulf of Mexico is also referred to as the Coastal Bend.
The San Gabriel River is a mostly-urban waterway flowing 58 miles (93 km) southward through Los Angeles and Orange Counties, California, in the United States. It is the central of three major rivers draining the Greater Los Angeles Area, the others being the Los Angeles River and Santa Ana River. The river's watershed stretches from the rugged San Gabriel Mountains to the heavily-developed San Gabriel Valley and a significant part of the Los Angeles coastal plain, emptying into the Pacific Ocean between the cities of Long Beach and Seal Beach.
Ballona Creek is an 8.5-mile (13.7 km) channelized stream in southwestern Los Angeles County, California, United States, that was once a "year-round river lined with sycamores and willows". The urban watercourse begins in the Mid-City neighborhood of Los Angeles, flows through Culver City and Del Rey, and passes the Ballona Wetlands Ecological Preserve, the sailboat harbor Marina del Rey, and the small beachside community of Playa del Rey before draining into Santa Monica Bay. The Ballona Creek drainage basin carries water from the Santa Monica Mountains on the north, from the Baldwin Hills to the south, and as far as the Harbor Freeway (I-110) to the east.
Laguna Atascosa National Wildlife Refuge is the largest protected area of natural habitat left in the Lower Rio Grande Valley. The 120,000-acre (49,000 ha) refuge is located almost entirely in Cameron County, Texas, 25 mi (40 km) east of Harlingen, although a very small part of its northernmost point extends into southern Willacy County.
The department of Norte de Santander in northwestern Colombia, and its capital, Cúcuta, contains several rivers. The rivers are mostly part of the Maracaibo Lake basin, with the southeastern section located in the Magdalena River basin. Important fluvial elements are the Zulia, Catatumbo and Pamplonita Rivers. The entity in charge of taking care of these hydrology of Norte de Santander is Corponor.
The World Birding Center is the official title given to a combined nine parks and nature preserves in the Rio Grande Valley region of Texas managed by a partnership of the Texas Parks and Wildlife Department, the United States Fish and Wildlife Service, and the local communities in which the parks reside. The stated mission of the World Birding Center is to "protect native habitat while increasing the understanding and appreciation of the birds and wildlife", with an additional emphasis on promoting local economic development through ecotourism.
The Tamaulipan mezquital, also known as the Brush Country, is a deserts and xeric shrublands ecoregion in the Southern United States and northeastern Mexico. It covers an area of 141,500 km2 (54,600 sq mi), encompassing a portion of the Gulf Coastal Plain in southern Texas, northern Tamaulipas, northeastern Coahuila, and part of Nuevo León.
The Resaca de la Palma Battlefield is the site in Brownsville, Texas, where American forces under General Zachary Taylor engaged Mexican forces under General Mariano Arista on May 9, 1846 in the Battle of Resaca de la Palma. A surviving undeveloped portion of the battlefield is now part of the Palo Alto Battlefield National Historical Park, and was designated a National Historic Landmark in 1960.

The Sabal Palm Sanctuary is a 557-acre (225-hectare) nature reserve and bird sanctuary located in the delta of the Rio Grande Valley in Cameron County near Brownsville, Texas. It is noted for being one of the last locations in the Rio Grande Valley with a profuse grove of sabal palms, an edible-heart-bearing palm much prized by pre-Hispanic inhabitants and noted by early explorers. As a relatively habitat-rich remnant of this Valley, it is a prized birdwatching and butterfly watching location for persons interested in the ecology of the Valley and adjacent states of northern Mexico.
Resaca de la Palma State Park is one of three state parks belonging to the World Birding Center and managed by the Texas Parks and Wildlife Department. At 1,200 acres, Resaca de la Palma State Park is the largest of the World Birding Center sites and is located in Brownsville. The property was acquired by the Texas Parks and Wildlife Department in 1977 and was opened to the public in December 2008. A resaca is a type of oxbow lake that can be found in Texas, and is a former channels of the Rio Grande. It is naturally cut off from the river, having no inlet or outlet.
The Rio Grande Valley is the river valley carved out by the Rio Grande as it flows through the American Southwest and northeastern Mexico, forming a part of the border region. In the US state of New Mexico, the river flows mostly north to south, and forms a valley near Cochiti Pueblo to the state line near El Paso, Texas along the floors of the large sedimentary basins of the Rio Grande Rift, and includes the narrow sections between the basins. It has been historically settled first by the Pueblo peoples, the Spanish, the Mexicans, and finally Anglo-Americans. As the largest river in the state, some of its most populous cities are located wholly or partially in the valley, including Albuquerque, New Mexico's largest city.
