Ririe is a city in Bonneville and Jefferson counties in the eastern part of the U.S. state of Idaho. It is part of the Idaho Falls metropolitan area. The population was 656 at the time of the 2010 census.
Bonneville Lock and Dam consists of several run-of-the-river dam structures that together complete a span of the Columbia River between the U.S. states of Oregon and Washington at River Mile 146.1. The dam is located 40 miles (64 km) east of Portland, Oregon, in the Columbia River Gorge. The primary functions of Bonneville Lock and Dam are electrical power generation and river navigation. The dam was built and is managed by the United States Army Corps of Engineers. At the time of its construction in the 1930s it was the largest water impoundment project of its type in the nation, able to withstand flooding on an unprecedented scale. Electrical power generated at Bonneville is distributed by the Bonneville Power Administration. Bonneville Lock and Dam is named for Army Capt. Benjamin Bonneville, an early explorer credited with charting much of the Oregon Trail. The Bonneville Dam Historic District was designated a National Historic Landmark District in 1987.
The Teton Dam was an earthen dam in the western United States, on the Teton River in eastern Idaho. It was built by the U.S. Bureau of Reclamation, one of eight federal agencies authorized to construct dams. Located between Fremont and Madison counties, it suffered a catastrophic failure on June 5, 1976, as it was filling for the first time.
The Dalles Dam is a concrete-gravity run-of-the-river dam spanning the Columbia River, two miles (3 km) east of the city of The Dalles, Oregon, United States. It joins Wasco County, Oregon with Klickitat County, Washington, 300 miles (309 km) upriver from the mouth of the Columbia near Astoria, Oregon. The closest towns on the Washington side are Dallesport and Wishram.
The Boise River is a 102-mile-long (164 km) tributary of the Snake River in the Northwestern United States. It drains a rugged portion of the Sawtooth Range in southwestern Idaho northeast of Boise, as well as part of the western Snake River Plain. The watershed encompasses approximately 4,100 square miles (11,000 km2) of highly diverse habitats, including alpine canyons, forest, rangeland, agricultural lands, and urban areas.
The Payette River is an 82.7-mile-long (133.1 km) river in southwestern Idaho and is a major tributary of the Snake River.
Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork of the Clearwater River in north central Idaho. In Clearwater County, the dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation.
Strawberry Reservoir is a large reservoir in the U.S. state of Utah. It is Utah's most popular fishery, receiving over 1.5 million angling hours annually and is part of the Blue Ribbon Fisheries program. Game fish in the reservoir include sterilized rainbow trout, bear lake cutthroat trout, kokanee salmon and crayfish. It is located 23 miles (37 km) southeast of Heber, Utah on U.S. Route 40. The reservoir is situated in Strawberry Valley. This valley is normally part of the Colorado River drainage. The dam was constructed to divert water into Utah Valley.
Blue Mesa Reservoir is an artificial reservoir located on the upper reaches of the Gunnison River in Gunnison County, Colorado. The largest lake located entirely within the state, Blue Mesa Reservoir was created by the construction of Blue Mesa Dam, a 390 feet (120 m) tall earthen fill dam constructed on the Gunnison by the U.S. Bureau of Reclamation in 1966 for the generation of hydroelectric power. Managed as part of the Curecanti National Recreation Area, a unit of the National Park Service, Blue Mesa Reservoir is the largest lake trout and Kokanee salmon fishery in Colorado.
The Kensico Reservoir is a reservoir spanning the towns of Armonk and Valhalla, New York, located 3 miles (5 km) north of White Plains. It was formed by the original earth and gravel Kensico Dam constructed in 1885, which impounded waters from the Bronx and Byram rivers. In 1917, a new masonry dam was completed, replacing the old dam and expanding the water supply by bringing water from the Catskill Mountains over a distance of more than 100 miles.
Dam removal is the process of demolishing a dam, returning water flow to the river. Arguments for dam removal consider whether their negative effects outweigh their benefits. The benefits of dams include hydropower production, flood control, irrigation, and navigation. Negative effects of dams include environmental degradation, such as reduced primary productivity, loss of biodiversity, and declines in native species; some negative effects worsen as dams age, like structural weakness, reduced safety, sediment accumulation, and high maintenance expense. The rate of dam removals in the United States has increased over time, in part driven by dam age. As of 1996, 5,000 large dams around the world were more than 50 years old. In 2020, 85% percent of dams in the United States are more than 50 years old. In the United States roughly 900 dams were removed between 1990 and 2015, and by 2015, the rate was 50 to 60 per year. France and Canada have also completed significant removal projects. Japan's first removal, of the Arase Dam on the Kuma River, began in 2012 and was completed in 2017. A number of major dam removal projects have been motivated by environmental goals, particularly restoration of river habitat, native fish, and unique geomorphological features. For example, fish restoration motivated the Elwha Ecosystem Restoration and the dam removal on the river Allier, while recovery of both native fish and of travertine deposition motivated the restoration of Fossil Creek.
Little Dell Reservoir is a reservoir in eastern Salt Lake County, Utah, United States, about 13 miles (21 km) east of Salt Lake City in the western Wasatch Mountains.
Heart Butte Dam is a dam in Grant County of southwestern North Dakota. The dam was a project of the United States Bureau of Reclamation completed in 1949, primarily for irrigation and flood control. The earthen dam is 142 feet in height and impounds the Heart River.
Lost Creek Dam is a dam in Morgan County, Utah, United States.
Virginia Smith Dam is a dam in Garfield County, Nebraska, about five miles northwest of Burwell.
Little Wood Dam, also known as the Little Wood River Dam, is a dam on the Little Wood River in central Blaine County, Idaho, United States, about 10 miles (16 km) miles northwest of Carey.
Prosser Creek Dam is a dam in Nevada County, California.
Salmon Lake Dam is a dam in Okanogan County, Washington.
Black Canyon Diversion Dam is a dam in Gem County, Idaho.
Willow Creek is a 84-mile (135 km) long tributary of the Snake River in the U.S. state of Idaho. Beginning at an elevation of 6,568 feet (2,002 m) east of the Blackfoot Mountains in southeastern Bingham County, it flows generally north into Bonneville County and past Bone. South of the town of Ririe, the creek is impounded by Ririe Dam, forming Ririe Reservoir. It then turns southwest, passing between Iona and Ucon, before bifurcating into two distributaries, North Fork Willow Creek and South Fork Willow Creek, at an elevation of 4,777 feet (1,456 m). Both forks reach the Snake River north of Idaho Falls.
