Small hydro is the development of hydroelectric power on a scale suitable for local community and industry, or to contribute to distributed generation in a regional electricity grid. Exact definitions vary, but a "small hydro" project is less than 50 megawatts (MW), and can be further subdivide by scale into "mini" (<1MW), "micro" (<100 kW), "pico" (<10 kW). In contrast many hydroelectric projects are of enormous size, such as the generating plant at the Three Gorges Dam at 22,500 megawatts or the vast multiple projects of the Tennessee Valley Authority.
The St. Marys River, sometimes written St. Mary's River, drains Lake Superior, starting at the end of Whitefish Bay and flowing 74.5 miles (119.9 km) southeast into Lake Huron, with a fall of 23 feet (7.0 m). For its entire length it is an international border, separating Michigan in the United States from Ontario, Canada.
The Platte River is a major American river, in the state of Nebraska. It is about 310 mi (500 km) long; measured to its farthest source via its tributary, the North Platte River, it flows for over 1,050 miles (1,690 km). The Platte River is a tributary of the Missouri River, which itself is a tributary of the Mississippi River which flows to the Gulf of Mexico. The Platte over most of its length is a broad, shallow, meandering stream with a sandy bottom and many islands—a braided stream.
The Loup River is a tributary of the Platte River, approximately 68 miles (109 km) long, in central Nebraska in the United States. The river drains a sparsely populated rural agricultural area on the eastern edge of the Great Plains southeast of the Sandhills. The name of the river means "wolf" in French, named by early French trappers after the Skidi band of the Pawnee, whose name means "Wolf People," and who lived along its banks. The river and its tributaries, including the North Loup, Middle Loup, and South Loup, are known colloquially as "the Loups", comprising over 1800 mi (2900 km) of streams and draining approximately one-fifth of Nebraska.
The Salt River Project (SRP) encompasses two separate entities: the Salt River Project Agricultural Improvement and Power District, an agency of the state of Arizona that serves as an electrical utility for the Phoenix metropolitan area, and the Salt River Valley Water Users' Association, a utility cooperative that serves as the primary water provider for much of central Arizona. It is one of the primary public utility companies in Arizona.
Fort Loudoun Dam is a hydroelectric dam on the Tennessee River in Loudon County, Tennessee, in the southeastern United States. The dam is operated by the Tennessee Valley Authority (TVA), which built the dam in the early 1940s as part of a unified plan to provide electricity and flood control in the Tennessee Valley and create a continuous 652-mile (1,049 km) navigable river channel from Knoxville, Tennessee to Paducah, Kentucky. It is the uppermost of nine TVA dams on the Tennessee River.
Newfoundland and Labrador Hydro, commonly known as Hydro, is a provincial Crown corporation that manages the generation, transmission and distribution of electricity in Newfoundland and Labrador, as well as portions of Quebec and the north-eastern areas of the United States. Between 2007 and 2021, NL Hydro was a subsidiary of the provincial Crown-owned energy holding company Nalcor Energy.
The McAlpine Locks and Dam are a set of locks and a hydroelectric dam at the Falls of the Ohio River at Louisville, Kentucky. They are located at mile point 606.8, and control a 72.9 miles (117.3 km) long navigation pool. The locks and their associated canal were the first major engineering project on the Ohio River, completed in 1830 as the Louisville and Portland Canal, designed to allow shipping traffic to navigate through the Falls of the Ohio.
Nebraska Public Power District (NPPD) is the largest electric utility in the state of Nebraska, serving all or parts of 84 counties. It was formed on January 1, 1970, when Consumers Public Power District, Platte Valley Public Power and Irrigation District (PVPPID) and Nebraska Public Power System merged to become Nebraska Public Power District. NPPD's predecessors were created through the efforts of the Nebraska legislature and financial agent Guy L. Myers as part of a system where all the investor-owned utilities operating in the state of Nebraska were condemned and their properties turned over to 'public power districts' being created at the time. NPPD is a public corporation and political subdivision of the state of Nebraska. The utility is governed by an 11-member Board of Directors, who are popularly elected from NPPD's chartered territory.
The Colorado–Big Thompson Project is a federal water diversion project in Colorado designed to collect West Slope mountain water from the headwaters of the Colorado River and divert it to Colorado's Front Range and plains. In Colorado, approximately 80% of the state's precipitation falls on the West Slope, in the Rocky Mountains, while around 80% of the state's growing population lives along the eastern slope, between the cities of Fort Collins and Pueblo.
The Nebraska Department of Transportation (NDOT) is the state government agency charged with building and maintaining the state highways in the U.S. state of Nebraska, as well as the state's airports.

Nebraska Highway 92 is a highway that enters the state from Nebraska's western border at the Wyoming state line west of Lyman, Nebraska, to the state's eastern border on the South Omaha Veterans Memorial Bridge over the Missouri River in Omaha, where it enters Iowa. Nebraska Highway 92 passes, follows, or runs through a number of the state's principal attractions, including Scotts Bluff National Monument, the Oregon Trail, Chimney Rock National Historic Site, Ash Hollow State Historical Park, Lake McConaughy, the Nebraska Sand Hills, and the City of Omaha. Nebraska Highway 92 is the longest state route in the state at a total of 489.1 miles (787.1 km), and is part of a continuous 886-mile (1,426 km) four-state "Highway 92" which begins in Torrington, Wyoming, goes through Nebraska and Iowa and ends in La Moille, Illinois. It is the only Nebraska Highway to run from the west border to the east border of Nebraska; along the way it crosses the Platte River or its tributary North Platte River a total of five times.
Lake McConaughy is a reservoir on the North Platte River. It is located 9 miles (14 km) north of Ogallala, Nebraska, United States, near U.S. Highway 26 and Nebraska Highway 61. The reservoir was named for Charles W. McConaughy, a grain merchant and mayor of Holdrege, Nebraska, one of the leading promoters of the project. Although he did not live to see the completion of the project, his leadership and perseverance eventually culminated in a public power and irrigation project that helped Nebraska become one of the nation's leading agricultural states.
Guernsey Dam is an earthfill dam on the North Platte River in Platte County in the U.S. State of Wyoming. The dam creates Guernsey Reservoir, the last of the 5 major reservoirs on the North Platte River in Wyoming. The dam contains a hydroelectric plant capable of 6.4 megawatts of electricity. The total capacity of the reservoir is 71,040 acre-feet (87,630,000 m3) of water which is used mainly for irrigation. Morrison-Knudsen and Utah Construction Company constructed Guernsey Dam and the hydroelectric plant as part of the North Platte Project to provide irrigation to eastern Wyoming and western Nebraska. Guernsey helps control the river flow and stores water released from the project's primary storage upstream at Pathfinder Reservoir. About 8 miles (13 km) downstream of the dam the Whalen Diversion Dam diverts water into the Fort Laramie and Interstate Canals that service farms in Wyoming and Nebraska.
