Texas has many irrigation canals with the majority of large canal networks in the Rio Grande Valley and the Gulf Coast, though smaller systems are located throughout the state. Canals provide water to dry climates to irrigate crops.
One large canal system in Texas is located along the Rio Grande near El Paso. The canal system begins at the American Diversion Dam on the Texas–New Mexico–Mexico border; it moves water into the American Canal on the U.S. side of the Rio Grande. This canal runs along the Rio Grande through the city of El Paso. Downstream from El Paso, the canal begins to divide into smaller canals (including the Franklin Canal) used to irrigate a great amount of the upper Rio Grande valley (El Paso and Hudspeth county water districts). The network is managed by the US Bureau of Reclamation. The major canals in this network are the Riverside Canal (El Paso) , American Canal , and the Franklin Canal . A similar canal system exists on the Mexican side of the river, beginning in Ciudad Juárez, Chihuahua.
A canal system had been planned in Eagle Pass since 1885, when rancher Patrick W. Thompson drew up plans for an irrigation canal network. Construction on the project commenced in 1889. Progress was stopped due to a lack of funding after only three miles of canal were built. Construction on the project did not begin again until 1926, when Capt. W. A. Fitch pushed for construction. The canal began operation in 1932, and in the early 1970s, the main canal ran 108 miles (174 km). Onions and figs were among the first crops grown here.
A large canal system is located in the lower Rio Grande valley, at the southernmost tip of Texas. The area is covered by 25 water districts, stretching three counties. The tropical climate of this area provides ideal conditions for growing citrus fruits, watermelons, and many other fruits and vegetables. It is the state's primary growing area for many crops, including citrus.
Another large system of canals in Texas is located on the Colorado River (not connected to the other Colorado River) in the Gulf Coast region. The canal network of 1,100 miles (1,800 km) is managed by the Lower Colorado River Authority (LCRA) and provides water to farm a region with inadequate and unreliable rainfall. Texas produces 7% of the nation's rice, and the majority of this rice is grown along the Colorado River. Nine pumping stations provide water to the canals. The network covers up to 91,500 acres (370 km2) in Colorado, Matagorda, and Wharton Counties.
The Phantom Lake Canal is a canal in West Texas. The canal is used for irrigating vineyards, orchards, and other crops. The excess water in the canal feeds Lake Balmorhea. (Also See Balmorhea Canals)
The Balmorhea canal system acquires water from San Solomon Springs and transports it to nearby farms for irrigation. The water leaves the San Solomon Springs swimming pool in Balmorhea State Park in one large canal. The canal begins to divide after it leaves the park.
The canals in East Texas serve several purposes including delivery of water to farms throughout the area. There are many separate canals, most of them located to the East of Houston and the West of Beaumont. The canals are often mistaken for drainage ditches, which are very common in the area. The canals can usually be identified by several characteristics:
Although the canals are mostly located in remote areas, they can be seen from I-10 in certain places, both following and crossing the highway. Other major highway canal crossings include US 90, US 69, US 96, and US 287 in Beaumont and the surrounding areas.

The Gulf Coast Water Authority operates several canals. The American Canal and Briscoe Canal systems were originally built to provide irrigation for rice and sugar cane farming in Brazoria, Fort Bend, and Galveston counties. Now they also supply municipal and industrial customers. The canals are fed by natural water from Oyster Creek augmented with water the GCWA pumps out of the Brazos River three miles south of Fulshear.

A large portion of the canals in Southeast Texas are owned and operated by the Lower Neches Valley Authority. The LNVA, the second river district created by the state of Texas, is currently one of 23 river districts in the state. The Lower Neches Valley Authority was granted authority by the Texas legislature in 1933 to operate within Hardin, Jefferson, and Tyler counties and eastern Chambers and Liberty counties. The LNVA system includes 400 miles of canals covering a 700 square mile area. The canals deliver fresh water to "...eight cities and water districts, 26 industries, and over 100 irrigated farms..." Water is drawn from the lower Neches River and Pine Island Bayou in north Beaumont with 21 large pumps delivering between 20,000 and 110,000 gallons of water a minute with a capability of delivering over one billion gallons of water a day.
A permanent saltwater barrier across the Neches River is located downstream of confluence of Pine Island Bayou and the Neches River within one-half mile of the confluence point. The barrier, constructed between 2000 and 2003, prevents saltwater contamination during periods of low river flows. The permanent saltwater barrier project had a budgeted cost of $50 million with the federal government paying 75% of the cost and the LNVA responsible for the remaining 25%. [3] The barrier, over 1,000 feet long, includes a 650 foot long overflow barrier; five forty-five foot wide tainter gates; and a fifty-six foot wide navigation lane regulated by two thirty foot sector gates. Temporary barriers were installed across Pine Island Bayou and the Neches River upstream of the confluence 36 times between 1940 and 2000 prior to construction of the permanent barrier.

The Sabine River Authority John W. Simmons Gulf Coast Canal System provides water for irrigation as well as industrial and municipal purposes. The system includes 75 miles of canals originating at the Sabine River nine miles north of Orange, Texas. Pumps can deliver more than 360 million gallons of water per day.
The Sabine River is a 360-mile (580 km) long river in the Southern U.S. states of Texas and Louisiana, From the 32nd parallel north and downstream, it serves as part of the boundary between the two states and empties into Sabine Lake, an estuary of the Gulf of Mexico.
The Rio Grande, known in Mexico as the Río Bravo del Norte or simply the Río Bravo, 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). 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 Neches River begins in Van Zandt County west of Rhine Lake and flows for 416 miles (669 km) through the piney woods of east Texas, defining the boundaries of 14 counties on its way to its mouth on Sabine Lake near the Rainbow Bridge. Two major reservoirs, Lake Palestine and B. A. Steinhagen Reservoir are located on the Neches. The Angelina River is a major tributary with its confluence at the north of Lake B. A. Steinhagen. Tributaries to the south include Village Creek and Pine Island Bayou, draining much of the Big Thicket region, both joining the Neches a few miles north of Beaumont. Towns and cities located along the river including Tyler, Lufkin, and Silsbee, although significant portions of the Neches River are undeveloped and flow through protected natural lands. In contrast, the lower 40 miles of the river are a major shipping channel, highly industrialized, with a number of cities and towns concentrated in the area including Beaumont, Vidor, Port Neches, Nederland, Groves, and Port Arthur.
The Lower Colorado River Authority (LCRA) is a nonprofit public utility created in November 1934 by the Texas Legislature. LCRA's mission is to enhance the lives of the Texans it serves through water stewardship, energy and community service. LCRA provides public power, manages the lower Colorado River, builds and operates transmission lines, owns public parks, and offers community services.
The Gulf Intracoastal Waterway is the portion of the Intracoastal Waterway located along the Gulf Coast of the United States. It is a navigable inland waterway running approximately 1,050 mi (1,690 km) from Carrabelle, Florida, to Brownsville, Texas.
Sabine Lake is a bay on the Gulf coasts of Texas and Louisiana, located approximately 90 miles (140 km) east of Houston and 160 miles (260 km) west of Baton Rouge, adjoining the city of Port Arthur. The lake is formed by the confluence of the Neches and Sabine Rivers and connects to the Gulf of Mexico through Sabine Pass. It forms part of the Texas–Louisiana border, falling within Jefferson and Orange Counties in Texas and Cameron Parish, Louisiana.
The Gulf Coastal Plain extends around the Gulf of Mexico in the Southern United States and eastern Mexico.
The Lower Neches Valley Authority was established in 1933 by the state legislature as a district to store, control, conserve, and utilize the water of the lower Neches River valley in Texas. The LNVA, the second river district created by the state of Texas, is currently one of 23 river districts in the state. It includes all of Jefferson, Hardin, and Tyler counties and parts of Jasper, Liberty, and Chambers counties.
The International Boundary and Water Commission is an international body created by the United States and Mexico in 1889 to apply the rules for determining the location of their international boundary when meandering rivers transferred tracts of land from one bank to the other, as established under the Convention of November 12, 1884.
The Riverside Canal is an irrigation canal in El Paso County beginning southeast of El Paso, Texas. The canal acquires water from the Riverside Diversion Dam on the Rio Grande 15 miles (24 km) southeast of El Paso. The canal is managed by the US Bureau of Reclamation. The canal extends for 17.2 miles (27.7 km) with a capacity of 900 cubic feet per second. Water from the canal irrigates about 39,000 acres (160 km2). The canal and diversion dam is the southernmost system on an irrigation project extending along the Rio Grande in New Mexico and Texas. The canal supplies a canal network extending throughout the Upper Rio Grande Valley.
The Franklin Canal is an irrigation canal in the Upper Rio Grande Valley near El Paso, Texas. The canal acquires water from the Rio Grande via the American Canal. The canal is 28.4 miles (45.7 km) long with a capacity of 325 cubic feet per second (9.2 m3/s).
The American Canal is an irrigation canal in the Upper Rio Grande Valley near El Paso, Texas. The canal acquires water from the Rio Grande from the American Diversion Dam at the Texas–New Mexico–Mexico border, 2 miles (3.2 km) northwest of downtown El Paso. The canal supplies the majority of the raw water to El Paso’s Johnathan-Roger Water Treatment Plant. It also mitigates flooding in south El Paso neighborhoods. The canal travels along the Rio Grande for 2.1 miles (3.4 km) where it flows into the Franklin Canal and the rest of the canal network. Construction of the canal dates back to 1938.
Interbasin transfer or transbasin diversion are terms used to describe man-made conveyance schemes which move water from one river basin where it is available, to another basin where water is less available or could be utilized better for human development. The purpose of such water resource engineering schemes can be to alleviate water shortages in the receiving basin, to generate electricity, or both. Rarely, as in the case of the Glory River which diverted water from the Tigris to Euphrates River in modern Iraq, interbasin transfers have been undertaken for political purposes. While ancient water supply examples exist, the first modern developments were undertaken in the 19th century in Australia, India and the United States, feeding large cities such as Denver and Los Angeles. Since the 20th century many more similar projects have followed in other countries, including Israel and China, and contributions to the Green Revolution in India and hydropower development in Canada.
The Rio Grande Project is a United States Bureau of Reclamation irrigation, hydroelectricity, flood control, and interbasin water transfer project serving the upper Rio Grande basin in the southwestern United States. The project irrigates 193,000 acres (780 km2) along the river in the states of New Mexico and Texas. Approximately 60 percent of this land is in New Mexico. Some water is also allotted to Mexico to irrigate some 25,000 acres (100 km2) on the south side of the river. The project was authorized in 1905, but its final features were not implemented until the early 1950s.
The American Dam, or American Diversion Dam, is a diversion dam on the Rio Grande in El Paso, Texas, that divides the river water between Mexico and the U.S. It is about 140 feet (43 m) north of the point where the west bank of the river enters Mexico, 3.5 miles (5.6 km) from the business center. The dam is operated by the International Boundary and Water Commission. It started operation in 1938.
The International Diversion Dam is a diversion dam on the Rio Grande in Ciudad Juárez. The dam is operated by the International Boundary and Water Commission, and diverts water into the Acequia Madre for use in irrigation in Mexico. Water is diverted under the terms of the 1906 treaty on usage of Rio Grande water between the United States and Mexico.
The Mesilla Diversion Dam is located in the Rio Grande about 40 miles (64 km) upstream of El Paso, Texas, about 6 miles (9.7 km) to the south of Las Cruces, New Mexico. It diverts water from the river for irrigation in the lower Mesilla Valley. The dam is owned by the United States Bureau of Reclamation, which built it, and is operated by the Elephant Butte Irrigation District.
The U.S. state of Texas has a series of estuaries along its coast on the Gulf of Mexico, most of them bounded by the Texas barrier islands. Estuaries are coastal bodies of water in which freshwater from rivers mixes with saltwater from the sea. Twenty-one drainage basins terminate along the Texas coastline, forming a chain of seven major and five minor estuaries: listed from southwest to northeast, these are the Rio Grande Estuary, Laguna Madre, the Nueces Estuary, the Mission–Aransas Estuary, the Guadalupe Estuary, the Colorado–Lavaca Estuary, East Matagorda Bay, the San Bernard River and Cedar Lakes Estuary, the Brazos River Estuary, Christmas Bay, the Trinity–San Jacinto Estuary, and the Sabine–Neches Estuary. Each estuary is named for its one or two chief contributing rivers, excepting Laguna Madre, East Matagorda Bay, and Christmas Bay, which have no major river sources. The estuaries are also sometimes referred to by the names of their respective primary or central water bodies, though each also includes smaller secondary bays, inlets, or other marginal water bodies.
