Bighorn Canyon National Recreation Area is a national recreation area established by an act of Congress on October 15, 1966, following the construction of the Yellowtail Dam by the Bureau of Reclamation. It is one of over 420 sites managed by the U.S. National Park Service. The recreation area spans 120,296.22 acres, straddling the border between Wyoming and Montana. It is divided into two distinct areas, the North District accessed via Fort Smith, Montana and the South District accessed through Lovell, Wyoming. There is no thru road inside the recreation area connecting the two districts. The Yellowtail Dam is located in the North District. It is named after the famous Crow leader Robert Yellowtail, harnesses the waters of the Bighorn River by turning that variable watercourse into Bighorn Lake. The lake extends 71 miles (114 km) through Wyoming and Montana, 55 miles (89 km) of which lie within the national recreation area. The lake provides recreational boating, fishing, water skiing, kayaking, and birding opportunities to visitors. About one third of the park unit is located on the Crow Indian Reservation. Nearly one-quarter of the Pryor Mountains Wild Horse Range lies within the Bighorn Canyon National Recreation Area.
Derby Dam is a diversion dam built from 1903 to 1905 on the Truckee River, located about 20 miles (32 km) east of Reno in Storey and Washoe counties in Nevada, United States. It diverts water into the Truckee Canal that would otherwise enter Pyramid Lake. The canal feeds Lake Lahontan reservoir in the Carson River watershed, where it is used for irrigation.
The Tuolumne River flows for 149 miles (240 km) through Central California, from the high Sierra Nevada to join the San Joaquin River in the Central Valley. Originating at over 8,000 feet (2,400 m) above sea level in Yosemite National Park, the Tuolumne drains a rugged watershed of 1,958 square miles (5,070 km2), carving a series of canyons through the western slope of the Sierra. While the upper Tuolumne is a fast-flowing mountain stream, the lower river crosses a broad, fertile and extensively cultivated alluvial plain. Like most other central California rivers, the Tuolumne is dammed multiple times for irrigation and the generation of hydroelectricity.
The Bighorn Mountains are a mountain range in northern Wyoming and southern Montana in the United States, forming a northwest-trending spur from the Rocky Mountains extending approximately 200 mi (320 km) northward on the Great Plains. They are separated from the Absaroka Range, which lie on the main branch of the Rockies to the west, by the Bighorn Basin. Much of the land is contained within the Bighorn National Forest.
Friant Dam is a concrete gravity dam on the San Joaquin River in central California in the United States, on the boundary of Fresno and Madera Counties. It was built between 1937 and 1942 as part of a U.S. Bureau of Reclamation (USBR) water project to provide irrigation water to the southern San Joaquin Valley. The dam impounds Millerton Lake, a 4,900-acre (2,000 ha) reservoir about 15 miles (24 km) north of Fresno.
The Stanislaus River is a tributary of the San Joaquin River in north-central California in the United States. The main stem of the river is 96 miles (154 km) long, and measured to its furthest headwaters it is about 150 miles (240 km) long. Originating as three forks in the high Sierra Nevada, the river flows generally southwest through the agricultural San Joaquin Valley to join the San Joaquin south of Manteca, draining parts of five California counties. The Stanislaus is known for its swift rapids and scenic canyons in the upper reaches, and is heavily used for irrigation, hydroelectricity and domestic water supply.
The Kaweah River is a river draining the southern Sierra Nevada in Tulare County, California in the United States. Fed primarily by high elevation snowmelt along the Great Western Divide, the Kaweah begins as four forks in Sequoia National Park, where the watershed is noted for its alpine scenery and its dense concentrations of giant sequoias, the largest trees on Earth. It then flows in a southwest direction to Lake Kaweah – the only major reservoir on the river – and into the San Joaquin Valley, where it diverges into multiple channels across an alluvial plain around Visalia. With its Middle Fork headwaters starting at almost 13,000 feet (4,000 m) above sea level, the river has a vertical drop of nearly two and a half miles (4.0 km) on its short run to the San Joaquin Valley, making it one of the steepest river drainages in the United States. Although the main stem of the Kaweah is only 33.6 miles (54.1 km) long, its total length including headwaters and lower branches is nearly 100 miles (160 km).
Yellowtail Dam is a dam across the Bighorn River in south central Montana in the United States. The mid-1960s era concrete arch dam serves to regulate the flow of the Bighorn for irrigation purposes and to generate hydroelectric power. The dam and its reservoir, Bighorn Lake, are owned by the U.S. Bureau of Reclamation.
The Central Utah Project is a US federal water project that was authorized for construction under the Colorado River Storage Project Act of April 11, 1956, as a participating project. In general, the Central Utah Project develops a portion of Utah's share of the yield of the Colorado River, as set out in the Colorado River Compact of 1922.
Buffalo Bill Dam is a concrete arch-gravity dam on the Shoshone River in the U.S. state of Wyoming. It is named after the famous Wild West figure William "Buffalo Bill" Cody, who founded the nearby town of Cody and owned much of the land now covered by the reservoir formed by its construction. The dam is part of the Shoshone Project, successor to several visionary schemes promoted by Cody to irrigate the Bighorn Basin and turn it from a semi-arid sagebrush-covered plain to productive agricultural land. Known at the time of its construction as Shoshone Dam, it was renamed in 1946 to honor Cody.
Scofield Reservoir is a 2,815-acre (11.39 km2) reservoir impounded by Scofield Dam, in Carbon County, Utah. Located on the Price River, a tributary of the Green River, Scofield Reservoir is adjacent to the northernmost boundary of the Manti–La Sal National Forest. The reservoir sits at an elevation of 7,618 feet (2,322 m), on the northern edge of the Wasatch Plateau. Utah State Route 96 runs along the western shoreline.
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 historical buildings and structures of Zion National Park represent a variety of buildings, interpretive structures, signs and infrastructure associated with the National Park Service's operations in Zion National Park, Utah. Structures vary in size and scale from the Zion Lodge to road culverts and curbs, nearly all of which were designed using native materials and regional construction techniques in an adapted version of the National Park Service Rustic style. A number of the larger structures were designed by Gilbert Stanley Underwood, while many of the smaller structures were designed or coordinated with the National Park Service Branch of Plans and Designs. The bulk of the historic structures date to the 1920s and 1930s. Most of the structures of the 1930s were built using Civilian Conservation Corps labor.
The Minidoka Project is a series of public works by the U.S. Bureau of Reclamation to control the flow of the Snake River in Wyoming and Idaho, supplying irrigation water to farmlands in Idaho. One of the oldest Bureau of Reclamation projects in the United States, the project involves a series of dams and canals intended to store, regulate and distribute the waters of the Snake, with electric power generation as a byproduct. The water irrigates more than a million acres (4,000 km²) of otherwise arid land, producing much of Idaho's potato crop. Other crops include alfalfa, fruit and sugar beets. The primary irrigation district lies between Ashton in eastern Idaho and Bliss in the southwestern corner of the state. Five main reservoirs collect water, distributing it through 1,600 miles (2,600 km) of canals and 4,000 miles (6,400 km) of lateral distribution ditches.
The Crow Creek Water Ditch is a historic water transportation system which brought water from Eureka Creek to where it was needed in gold placer mining in the Indian Creek drainage area where gold was discovered in 1866. It is located near Townsend, Montana. It was built between 1866 and c.1875 originally to support gold mining, which required water, then later was used for farm and ranch irrigation.
The Colorado River is a major river of the western United States and northwest Mexico in North America. Its headwaters are in the Rocky Mountains where La Poudre Pass Lake is its source. Located in north central Colorado it flows southwest through the Colorado Plateau country of western Colorado, southeastern Utah and northwestern Arizona where it flows through the Grand Canyon. It turns south near Las Vegas, Nevada, forming the Arizona–Nevada border in Lake Mead and the Arizona–California border a few miles below Davis Dam between Laughlin, Nevada and Needles, California before entering Mexico in the Colorado Desert. Most of its waters are diverted into the Imperial Valley of Southern California. In Mexico its course forms the boundary between Sonora and Baja California before entering the Gulf of California. This article describes most of the major features along the river.
The Grand Valley Diversion Dam is a diversion dam in the De Beque Canyon of the Colorado River, about 15 miles (24 km) northeast of Grand Junction, Colorado in the United States. It is a 14-foot (4.3 m) high, 546-foot (166 m) long concrete roller dam with six gates, which were the first and largest of their kind to be installed in the United States.
Avalon Dam is a small dam on the Pecos River about 5 miles (8.0 km) north of Carlsbad, New Mexico, United States. The dam is a storage and regulating reservoir, and diverts water into the main canal of the Carlsbad Project, an irrigation scheme.
The Percha Diversion Dam is a structure built in 1918 on the Rio Grande in New Mexico, United States. It diverts water from the Rio Grande into the Rincon Valley Main Canal, an irrigation canal.
The Hurricane Canal is a hand-excavated irrigation canal that diverted water from the Virgin River to the east side of Hurricane, Utah, United States.
