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, resacas. When the seasonal flooding ended and the river retreated, the newly formed oxbow lakes remained, creating resacas all throughout the Rio Grande Valley. [4]
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. [5]
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 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.
The Bosque del Apache National Wildlife Refuge is located in southern New Mexico. It was founded in 1939 and is administered by the U.S. Fish and Wildlife Service. The Piro people lived in the lands around what is now the refuge until the 1600s, when they were forced to abandon their pueblos due to European diseases and attacks from the Apache tribes. It is a favorite spot to watch the migration of the sandhill cranes in the fall. The reserve is open year-round and provides safe harbor for its varied wildlife. Visitors to the refuge also enjoy partaking in activites such as hiking, cycling, driving tours on the 12-mile scenic auto route, and participating in educational programs offered at the park.
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, 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 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 is a deserts and xeric shrublands ecoregion in the Southern United States and northeastern Mexico.

The Willamette Valley ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency in the U.S. states of Oregon and Washington. Slightly larger than the Willamette Valley for which it is named, the ecoregion contains fluvial terraces and floodplains of the Willamette River system, scattered hills, buttes, and adjacent foothills. It is distinguished from the neighboring Coast Range, Cascades, and Klamath Mountains ecoregions by lower precipitation, lower elevation, less relief, and a different mosaic of vegetation. Mean annual rainfall is 37 to 60 inches, and summers are generally dry. Historically, the region was covered by rolling prairies, oak savanna, coniferous forests, extensive wetlands, and deciduous riparian forests. Today, it contains the bulk of Oregon's population, industry, commerce, and agriculture. Productive soils and a temperate climate make it one of the most important agricultural areas in Oregon.
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.
