Bay on the Texas coast, United States of America

Matagorda Bay (/audio=En us Matagorda. ogg/,/m//æ//t//ə/'/g//ɔər//d//ə///) is a large Gulf of Mexico bay on the Texas coast, lying in Calhoun and Matagorda counties and located approximately 80 mile (129 km) northeast of Corpus Christi, 143 mile (230 km) east southeast of San Antonio, 108 mile (174 km) south southwest of Houston, and 167 mile (269 km) south southeast of Austin. It is one of seven major estuaries along the Gulf Coast of Texas and serves as the mouth of numerous streams, most notably the Lavaca and Colorado Rivers. The Texas seaport of Port Lavaca is located on the system's northwestern extension of Lavaca Bay. The city of Palacios is found on northeastern extension of Tres Palacios Bay, and Port O'Connor is located on the southwestern tip of the main bay's shore. The ghost town of Indianola, which was a major port before it was destroyed by two hurricanes in the late 19th century, is also found on the bay. The bay is separated from the Gulf of Mexico by Matagorda Peninsula. Its shore, especially near the Colorado River delta, provides a habitat for a wide variety of wildlife. The wildlife serves as a basis for the birding and fishing tourism, and is an essential component of the production of seafood, specifically shrimp and blue crab, which are the specialties of the area. The fertile land near the bay is ideal for farming, especially for the propagation of rice.

Early European records suggest that the bay and the surrounding area went by the names Espíritu Santo and Costa y Bahía de San Bernardo. Spanish explorer Alonso Álvarez de Pineda's map from the late 1510s appears to be the first documentation of the bay. In 1685, French explorer René Robert Cavelier, Sieur de La Salle established the colony of Fort St. Louis along the bay's shore after missing the entrance to the Mississippi River. Half of the colonists were killed by disease, and the other half, save for five children, were killed by Karankawa Indians. It was afterward referred to as a "lost colony." The Indians kept the children until they were rescued by the Spanish during the Alonso De León and Domingo Terán de los Ríos expeditions near the bay. In 1722 Spanish built a fort, Presidio La Bahia, and Mission Nuestra Señora del Espíritu Santo de Zúñiga on the site of Fort Saint Louis. The port of Linnville was established on Matagorda Bay in 1831, and served as a main port for the Republic of Texas. The Great Comanche Raid of 1840 destroyed the town and forced the inhabitants to flee to the nearby Labbacca, which would later become known as Port Lavaca. Lavaca or la vaca, Spanish for cow, was founded in the wake of the Comanche Raid in 1841. It replaced Linnville as the main port on Matagorda Bay. However, the sandbar heavy Lavaca Bay caused some navigational problems for ships. As a result, Lavaca was surpassed by Indianola as the main port on Matagorda Bay in the 1850s, even though the sandbars were dredged later in the decade. Indianola had been founded in 1846 as a landing place for German immigrants. It rapidly developed into a major seaport, and became the second largest in the state (after Galveston) by the 1860s. The two ports, and strategic control of Matagorda Bay in particular, became important during the American Civil War. Control of the bay shifted between the Union and Confederate forces several times. The Union presence in the area ended in June 1864. Before 1900, East Matagorda Bay was a free flowing extension, which formed the eastern segment of Matagorda Bay. Flooding and drainage issues caused by the Colorado River, which at the time emptied into the bay, precipitated a massive dredging campaign in the 1920s. Flooding was not remedied by the dredging, as sediment deposited in the bay and formed a tidal marsh that grew at a year. As a result, local citizens decided to change the course of the Colorado River in 1934 to bypass Matagorda Bay into the Gulf of Mexico, the dredging from this project causing the split and forming the isolated East Matagorda Bay.

The shoreline of the bay is included in the Texas Coastal Plain. At the eastern end, near the Colorado River delta, there is a swampy terrain, with an abundance of wetlands and tidal marshes. Extended coastal prairies supporting native grasses, can be found throughout the area. On average, the Matagorda Bay system is deep, and covers approximately The main extensions include: Lavaca Bay, which extends westward to the mouth of the Lavaca River; Tres Palacios Bay, which extends northeast to the mouth of the Tres Palacios River and East Matagorda Bay, which is nearly isolated from the system by the Colorado River delta. Other inlets include Turtle Bay, Carancahua Bay, Keller Bay, and Cox Bay. Together with its extensions, Matagorda Bay forms one of seven major estuaries along the Gulf Coast of Texas, and the third largest estuarine system in Texas behind Galveston Bay and Laguna Madre.

A wide variety of wildlife can be found in and around Matagorda Bay. The Mad Island Oyster Lake conservation area, located on the eastern shore of Matagorda Bay, is a habitat for over 300 species of birds including songbirds, shorebirds and waterfowl. More species of birds were found in the area than any other in the nation during the National Audubon Society's annual Christmas Bird Count from 2000 to 2002. Other fauna located along the bay include bobcats, white tailed deer, river otters, Texas horned lizards, reddish egret, white tailed hawk, peregrine falcon, the piping plover and alligators. smooth puffer, sand seatrout, spotted seatrout, blacktip shark, gray snapper, southern stingray, Gulf toadfish and tripletail. The bay serves as a nursery for finfish, shrimp and crabs. Recreational fishing also contributes to the local economies via tourism. Tourists often flock to the Port Lavaca State Fishing Pier, which is a major point of interest for fishermen. Other activities for visitors include hunting, oyster roasts, beach combing and birding. Several manufacturing complexes have been erected along the bay, which employ local residents. The Aluminum Company of America, Union Carbide, Du Pont, and Formosa Plastics all established plants in Point Comfort. The South Texas Nuclear Generating Station is found in nearby Bay City. Petroleum and natural gas were discovered in the bay in the 1930s. Maize, cotton, soybeans, turf, and rice grow well around the bay, especially in the fertile delta region.
