The San Acacia Diversion Dam is a structure built in 1934 for the Middle Rio Grande Conservancy District (MRGCD) near to San Acacia, New Mexico, United States. It diverts water from the Rio Grande into irrigation canals.
The dam is location on the Rio Grande about 0.75 miles (1.21 km) north of San Acacia, New Mexico. There are significant archeological sites along the left abutment of the diversion dam and the river embankments. [1] There is a spoil levee about 500 feet (150 m) upstream from the dam. Scour by the river on the bank here was causing persistent bank erosion. [2]
The dam was built in 1934 and rehabilitated by the Bureau of Reclamation in 1957 as part of the Middle Rio Grande Project. It is 17 feet (5.2 m) high and 700 feet (210 m) long, a concrete structure with 29 radial gates. The dam serves the Socorro Division, and has a diversion capacity of 283 cubic feet (8.0 m3) per second. [3] The dam diverts river water into the Socorro Main Canal operated by the MRGCD. It can also divert water into the Low Flow Conveyance Channel, operated by the United States Bureau of Reclamation. [1] The Low Flow Conveyance Channel runs along the Rio Grande for 58 miles (93 km) from the San Acacia Diversion Dam to the narrows above Elephant Butte Reservoir. [4]
A 2003 report noted that there had been silting upstream of the dam but the width of the downstream channels had decreased sharply since the diversion dam was built. The river has cut a deeper channel in its bed and now runs faster. This made it harder for fish to travel upstream. The report suggested that if eight Gradient Restoration Facilities were installed in the downstream reach, that should be enough to slow the water, allowing sediment to settle and making fish passage easier. [5] A 2005 report considered removing the dam altogether. Again, it suggested emplacement of Gradient Restoration Facilities to control erosion as sediment above and below the dam returned to normal levels. [6]
Concerns about the survival of the endangered Rio Grande silvery minnow raised in Rio Grande Silvery Minnow v. Bureau of Reclamation led to the United States Bureau of Reclamation working with the United States Fish and Wildlife Service (USFWS) to try to rescue the fish. A number of projects are being undertaken to restore the silvery minnow's habitat, including a study of ways to allow the fish to pass the diversion dam. [4] A requirement for a fish passage was given in the Biological Opinion (BO) issued in March 2003 by the USFWS. [1] Water has been released from upstream reservoirs to supply more water to the habitat of the silvery minnow, and the Department of Reclamation is leasing water from the owners of water rights for this purpose. Water from the Low Flow Conveyance Channel is being pumped into sections of the river that regularly run dry. [4]
The Imperial Diversion Dam is a concrete slab and buttress, ogee weir structure across the California/Arizona border, 18 miles (29 km) northeast of Yuma. Completed in 1938, the dam retains the waters of the Colorado River into the Imperial Reservoir before desilting and diversion into the All-American Canal and the Gila Project aqueduct. Between 1932 and 1940, the Imperial Irrigation District (IID) relied on the Inter-California Canal and the Imperial Canal and Alamo River.
In 1942, the Coleman National Fish Hatchery was established under an act of the U.S. Congress to mitigate the loss of historic spawning habitat caused by the construction of dams. The fish hatchery is located in Shasta County, California, near the town of Anderson on the north bank of Battle Creek approximately 6 river miles (9.7 km) east of the Sacramento River. Coleman NFH covers approximately 75 acres (300,000 m2) of land owned by the U.S. Fish and Wildlife Service (USFWS), with an additional 63 acres (250,000 m2) of land in perpetual easements for pipelines and access. It is the largest salmon hatchery in the continental United States.
The Rio Grande silvery minnow or Rio Grande minnow is a small herbivorous North American fish. It is one of the seven North American members of the genus Hybognathus, in the cyprinid family.
Navajo Dam is a dam on the San Juan River, a tributary of the Colorado River, in northwestern New Mexico in the United States. The 402-foot (123 m) high earthen dam is situated in the foothills of the San Juan Mountains about 44 miles (71 km) upstream and east of Farmington, New Mexico. It was built by the U.S. Bureau of Reclamation (Reclamation) in the 1960s to provide flood control, irrigation, domestic and industrial water supply, and storage for droughts. A small hydroelectric power plant was added in the 1980s.
Savage Rapids Dam was an approximately 39-foot-high (12 m), 500-foot-long (150 m) irrigation diversion dam spanning the mainstem of the Rogue River in Josephine County, Oregon. The dam was demolished and removed in 2009. From 1921 until the spring of 2009, the Savage Rapids Dam almost entirely functioned for irrigation purposes, and it did not provide any flood control, hydro-electric power, inland waterway, or other significant beneficial uses. It only provided very minor recreational or wildlife benefits.
The Palo Verde Dam is a diversion dam on the Colorado River in La Paz County, Arizona, and Riverside County, California, in the southwestern United States, approximately 9 miles (14 km) northeast of Blythe. The dam is earthen and rockfill, built solely to divert water into irrigation canals serving the Palo Verde Irrigation District. It measures 1,850 feet (560 m) long at its crest, which is at an elevation of 283.5 feet (86.4 m), and stands 46 feet (14 m) high above the riverbed, containing approximately 175,000 cubic yards (134,000 m3) of material. Construction of the dam, which began in 1956 and ended in 1958, was authorized by the U.S. Bureau of Reclamation. The dam was constructed to raise the water level of the river because the upstream Hoover and Davis Dams blocked sediment, causing significant degradation of the riverbed that hampered water diversion.
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.
El Vado Dam impounds the Rio Chama in the U.S. state of New Mexico, about 105 miles (169 km) north-northwest of New Mexico's largest city, Albuquerque and about 80 miles (130 km) northwest of the capital city of Santa Fe. The earth-filled structure forms El Vado Lake, a storage reservoir for the Middle Rio Grande Project, and has been designated as a New Mexico Historic Civil Engineering Landmark by the American Society of Civil Engineers.
The San Juan–Chama Project is a U.S. Bureau of Reclamation interbasin water transfer project located in the states of New Mexico and Colorado in the United States. The project consists of a series of tunnels and diversions that take water from the drainage basin of the San Juan River – a tributary of the Colorado River – to supplement water resources in the Rio Grande watershed. The project furnishes water for irrigation and municipal water supply to cities along the Rio Grande including Albuquerque and Santa Fe.
The Albuquerque Basin is a structural basin and ecoregion within the Rio Grande rift in central New Mexico. It contains the city of Albuquerque.
San Acacia is a small unincorporated community and census-designated place in Socorro County, New Mexico, United States. It was once a prosperous railway town, but is now largely deserted. There is a nearby diversion dam on the Rio Grande, important in irrigation.
The Middle Rio Grande Conservancy District (MRGCD) was formed in 1925 to manage the irrigation systems and control floods in the Albuquerque Basin. It is responsible for the stretch of river from the Cochiti Dam in Sandoval County in the north, through Bernalillo County, Valencia County and Socorro County to the Elephant Butte Reservoir in the south. It manages the Angostura, Isleta and San Acacia diversion dams, which feed an extensive network of irrigation canals and ditches.
The Angostura Diversion Dam is a diversion dam on the Rio Grande in Sandoval County. New Mexico, near to Algodones and to the north of Bernalillo. The dam diverts water into the main irrigation canal serving the Albuquerque Division.
The Isleta Diversion Dam is a structure on the Rio Grande in the Albuquerque Basin near Isleta Village Proper, New Mexico that diverts water from the river into irrigation canals. There have been some negative environmental impacts due to changes in the river flow that affect the native fish and drying of the riverside land.
Rio Grande Silvery Minnow v. Bureau of Reclamation, called Rio Grande Silvery Minnow v. Keys in its earlier phases, was a case launched in 1999 by a group of environmentalists against the United States Bureau of Reclamation and the United States Army Corps of Engineers alleging violations of the Endangered Species Act and the National Environmental Policy Act. The case resulted in significant changes to water and river management in the Middle Rio Grande Basin of New Mexico in an effort to reverse the damage that had been done to the habitat of two endangered species.
The Middle Rio Grande Project manages water in the Albuquerque Basin of New Mexico, United States. It includes major upgrades and extensions to the irrigation facilities built by the Middle Rio Grande Conservancy District and modifications to the channel of the Rio Grande to control sedimentation and flooding. The bulk of the work was done by the United States Bureau of Reclamation and the United States Army Corps of Engineers in the 1950s, but construction continued into the 1970s and maintenance is ongoing. The project is complementary to the San Juan–Chama Project, which transfers water from the San Juan River in the Colorado River Basin to the Rio Grande. Although distribution of water from the two projects is handled through separate allotments and contracts, there is some sharing of facilities including the river itself. The ecological impact on the river and the riparian zone was the subject of extended litigation after a group of environmentalists filed Rio Grande Silvery Minnow v. Bureau of Reclamation in 1999.
Heron Dam is a storage dam Rio Arriba County, in northern New Mexico in the southwestern United States, just north of the El Vado Dam. It is owned and operated by the United States Bureau of Reclamation. The dam is about 9 miles west of the town of Tierra Amarilla.
The Riverside Diversion Dam was a diversion dam on the Rio Grande to the southeast of El Paso, Texas. The dam was owned by the United States Bureau of Reclamation, and diverted water into the Riverside Canal for use in irrigation in the El Paso Valley. The dam became obsolete with completion of a cement-lined canal carrying water from the upstream American Diversion Dam to the head of the canal. It was partially removed in 2003.
Red Bluff Diversion Dam is a disused irrigation diversion dam on the Sacramento River in Tehama County, California, United States, southeast of the city of Red Bluff. Until 2013, the dam provided irrigation water for two canals that serve 150,000 acres (61,000 ha) of farmland on the west side of the Sacramento Valley. The dam and canals are part of the Sacramento Canals Unit of the Central Valley Project, operated by the U.S. Bureau of Reclamation. In 2013, the dam was decommissioned and the river allowed to flow freely through the site in order to protect migrating fish. A pumping plant constructed a short distance upstream now supplies water to the canal system.
