Newaygo County is a county in the U.S. state of Michigan. As of the 2020 United States Census, the population was 49,978. The county seat is White Cloud. The county was created in 1840, and was organized in 1851. It was either named for an Ojibwe leader who signed the Treaty of Saginaw in 1819 or for an Algonquian word meaning "much water".
The Muskegon River is a river in the western portion of the lower peninsula of the U.S. state of Michigan. The river source is located at Houghton Lake in Roscommon County, flowing out of the North Bay into neighboring Missaukee County. The river passes through Clare County, Osceola County, Mecosta County, Newaygo County, and Muskegon County, and generally flows southwesterly to its mouth at Muskegon, Michigan, where it empties into Muskegon Lake. Muskegon Lake is connected to Lake Michigan via a mile-long channel. The river has several major branches, such as the Hersey River, Cedar Creek and Little Muskegon River. The primary river channel is 216 miles (348 km) long and drains an area of 2,350 square miles (6,100 km2). In September 2002, an article in National Geographic raised concerns about a controversial deal made with Nestlé Waters North America, giving them permission "to bottle up to 210 million gallons a year from an aquifer north of Grand Rapids, Michigan that recharges the Muskegon River".
Garrison Dam is an earth-fill embankment dam on the Missouri River in central North Dakota, U.S. Constructed by the U.S. Army Corps of Engineers from 1947 to 1953, at over 2 miles (3.2 km) in length, the dam is the fifth-largest earthen dam in the world. The reservoir impounded by the dam is Lake Sakakawea, which extends to Williston and the confluence with the Yellowstone River, near the Montana border.
Cushman Dam No. 1 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, which in derogation of the natural and treaty rights of the Native inhabitants impounded and enlarged the formerly natural Lake Cushman, leading to damage claims in excess of $5 billion and an eventual settlement agreement with the Skokomish tribe that terminates the right to operate the dam(s) after 2048. It was built by Tacoma City Light in 1924–1926. Tacoma's demand for electricity grew rapidly after World War I. Tacoma City Light's Nisqually River Hydroelectric Project, built in 1912, could not meet the demand and the utility decided to build a new hydroelectric project on the North Fork Skokomish River. The dam and powerhouse first began to deliver electricity on February 12, 1926.
Cushman Dam No. 2 is a hydroelectric dam on the North Fork of the Skokomish River in Mason County, Washington, United States, forming Lake Kokanee. Built in 1930, its three 27,000 kilowatt generators provide 233 million kilowatt-hours annually to the Tacoma Power system. Along with Cushman Dam No. 1, it is part of Tacoma Power's Cushman Project.
Prado Dam is an earth-fill dry dam across the Santa Ana River at the Chino Hills near Corona, California in Riverside County with the resulting impounded water creating Prado Flood Control Basin reservoir. The U.S. Army Corps of Engineers built the dam in Lower Santa Ana River Canyon. Its primary purpose is flood control and it is the downstream element of the Santa Ana River's flood control system, which is a natural constriction about 30.5 mi (49.1 km) upstream from the ocean. The area upstream from the dam contains 2,255 sq mi (5,840 km2) of the watershed's 2,650 sq mi (6,900 km2). The dam's construction was authorized in 1936 and the flood of 1938 demonstrated its necessity. Construction was completed in 1941. Prado Flood Control Basin also provides water storage for groundwater recharge operations.
Bagnell Dam impounds the Osage River in the U.S. state of Missouri, creating the Lake of the Ozarks. The dam is located in the city of Lakeside in Miller County, near the Camden-Miller County line. The 148-foot (45 m) tall concrete gravity dam was built by the Union Electric Company to generate hydroelectric power at its Osage Powerplant. It is 2,543 feet (775 m) long, including a 520-foot (160 m) long spillway and a 511-foot (156 m) long power station. The facility with eight generators has a maximum capacity of 215 megawatts. The dam provides power to 42,000 homes.

Swan Falls Dam is a concrete gravity type hydroelectric dam in the western United States, on the Snake River in southwestern Idaho, United States. At the dam, the river is the border of Ada and Owyhee counties; it is approximately five miles (8 km) east of Murphy, the seat of Owyhee County.
Croton Dam is an earth-filled embankment dam and powerplant complex on the Muskegon River in Croton Township, Newaygo County, Michigan. It was built in 1907 under the direction of William D. Fargo by the Grand Rapids - Muskegon Power Company, a predecessor of Consumers Energy. The 40-foot-high (12 m) dam impounds 7.2 billion U.S. gallons (6 billion imp. gal/27 billion L) of water in its 1,209-acre (489 ha) reservoir and is capable of producing 8,850 kilowatts at peak outflow. It was listed on the National Register of Historic Places in 1979.
Ryan Dam is a hydroelectric dam on the Missouri River, 10 miles (16 km) downstream from the city of Great Falls in the U.S. state of Montana. The dam is 1,336 feet (407 m) long and 61 feet (19 m) high; its reservoir is 7 miles (11 km) long and has a storage capacity of 5,000 acre-feet (6,200,000 m3). It is a run-of-river dam. The dam is built on the largest of the five Great Falls of the Missouri, the "Big Falls", also sometimes called "Great Falls". Since 1915, the six-unit powerhouse on the left side of the dam has occupied a significant portion of the 87-foot (27 m) high waterfall.
Tieton Dam is an earth and concrete type dam on the Tieton River in Yakima County, in the U.S. state of Washington. The dam began operation in 1925. Its reservoir, Rimrock Lake, has a total capacity of 203,600 acre-feet (0.2511 km3) with a normal operating capacity of 198,000 acre-feet (0.244 km3) to provides water for agricultural irrigation. This dam is a component of the Yakima Project. Tieton Dam also produces electricity for Burbank Water and Power and Glendale Water and Power, near Los Angeles. The Southern California Public Power Agency installed two 7 megawatt generators in a project started in 2010. The power is transmitted over the DC Intertie that runs from Celilo, Oregon to Sylmar, California. Upstream from the dam, the river is impounded by Clear Creek Dam, another element of the Yakima Project. About 8 miles (13 km) downstream from the dam, the Tieton River is tapped for the Tieton Main Canal.

The total installed capacity is 362.3 megawatts (MW), producing an annual average of 1,171.9 gigawatt hours (GWh). The project is also contracted for the delivery of irrigation water between March 31 and October 31 of each year. The project is owned and operated by Pacific Gas and Electric Company.
Rogers Dam is an earth-filled embankment dam on the Muskegon River in Mecosta Township, Michigan, United States. It is located about six miles (9.7 km) south of Big Rapids. Construction of the dam began in 1905, and its power plant was commissioned in March 1906. Owned and operated by Consumers Energy, the primary purpose of the dam is hydroelectric power generation. On December 22, 1921, the original 4.5-megawatt (6,000 hp) power plant was destroyed in a fire. It was rebuilt with an increased 6.8-megawatt (9,100 hp) installed capacity in 1922. The rebuild cost approximately $450,000. It is the oldest hydroelectric power plant operated by Consumers Energy who owns the Hardy and Croton dams downstream of Rogers Dam.
