The river is navigable its entire length via a series of locks and dams.
The Kentucky River is a tributary of the Ohio River, 260 miles (418 km) long, in the U.S. Commonwealth of Kentucky. The river and its tributaries drain much of the central region of the state, with its upper course passing through the coal-mining regions of the Cumberland Mountains, and its lower course passing through the Bluegrass region in the north central part of the state. Its watershed encompasses about 7,000 square miles (18,000 km2). It supplies drinking water to about one-sixth of the population of the Commonwealth of Kentucky.
Caesar Creek State Park is located in southwestern Ohio, five miles (8 km) east of Waynesville, in Warren, Clinton, and Greene counties. The park is leased by the State from the U.S. Army Corps of Engineers, who in the 1970s erected a dam on Caesar Creek to impound a 2,830-acre (1,150 ha) lake. The total park area, including the lake, is 7,941-acre (3,214 ha). The park has 43 miles (69 km) of hiking trails and 31 miles (50 km) of bridle trails.
Lake Cumberland is a reservoir in Clinton, Laurel, McCreary, Pulaski, Russell, and Wayne counties in Kentucky. The primary reasons for its construction were a means for flood control and the production of hydroelectric power. Its shoreline measures 1,255 miles (2,020 km) and the lake covers 65,530 acres (265 km2) at the maximum power pool elevation. The reservoir ranks 9th in the U.S. in size, with a capacity of 6,100,000 acre feet (7.5 km3) of water, enough to cover the entire Commonwealth of Kentucky with 3 inches (76 mm) of water. The main lake is 101 miles (163 km) long and over one mile (1.6 km) across at its widest point.
Lake Barkley, a 58,000-acre (230 km2) reservoir in Livingston County, Lyon County and Trigg County in Kentucky and extending into Stewart County and Houston County in Tennessee, was impounded by the U.S. Army Corps of Engineers in 1966 upon the completion of Barkley Dam. Both the lake and the dam are named for Vice President Alben Barkley, a Kentucky native.
The Dale Hollow Reservoir is a reservoir situated on the Kentucky/Tennessee border. The lake is formed by the damming of the Obey River, 7.3 miles (12 km) above its juncture with the Cumberland River at river mile 380. Portions of the lake also cover the Wolf River. Dale Hollow is one of four major flood control reservoirs for the Cumberland; the others being J. Percy Priest Dam, Wolf Creek Dam, and Center Hill Dam. It is also the site of Dale Hollow Lake State Park on the north (Kentucky) side.
Edgar Evins State Park is a state park in DeKalb County, Tennessee, in the southeastern United States. The park consists of 6,000 acres (24 km2) along the shores of Center Hill Lake, an impoundment of the Caney Fork. The State of Tennessee leases the land from the U.S. Army Corps of Engineers.
Center Hill Lake is a reservoir in the U.S. state of Tennessee. It is located in Middle Tennessee near Smithville. Created by means of a dam constructed by the U.S. Army Corps of Engineers in 1948, the lake had a dual purpose: electricity production and flood control. Center Hill Dam is 260 ft (79 m) high, and it is composed of concrete and earth structures, with 8 gates that are 50 ft (15 m) wide each. Center Hill Lake is one of four major flood control reservoirs for the Cumberland; the others being J. Percy Priest Dam, Dale Hollow Dam, and Wolf Creek Dam.
The West Fork River is a principal tributary of the Monongahela River, 103 miles (166 km) long, in north-central West Virginia in the United States. Via the Monongahela and Ohio Rivers, it is part of the watershed of the Mississippi River, draining an area of 881 square miles (2,284 km²) on the unglaciated portion of the Allegheny Plateau.
The Tygart Valley River — also known as the Tygart River — is a principal tributary of the Monongahela River, approximately 135 miles (217 km) long, in east-central West Virginia in the United States. Via the Monongahela and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 1,329 square miles (3,440 km2) in the Allegheny Mountains and the unglaciated portion of the Allegheny Plateau.
Dworshak Dam is a concrete gravity dam in the western United States, on the North Fork Clearwater River in Clearwater County, Idaho. The dam is located approximately four miles (6 km) northwest of Orofino and impounds the Dworshak Reservoir for flood control and hydroelectricity generation. With a height of 717 feet (219 m), Dworshak is the third tallest dam in the United States and the tallest straight-axis concrete dam in the Western Hemisphere. Construction of the dam by the U.S. Army Corps of Engineers (USACE) began in 1966 and was completed in 1973.
Dewey Lake, located near Prestonsburg, Kentucky in Floyd County, is part of the integrated flood reduction system operated by the United States Army Corps of Engineers for the entire Ohio River Basin.
Fishtrap Lake is a 1,130-acre (5 km2) reservoir in Pike County, Kentucky. Dedicated by President Lyndon B. Johnson in 1968, the lake was formed by the impounding of the Levisa Fork of the Big Sandy River at the 195-foot-high Fishtrap Dam by the United States Army Corps of Engineers.
El Dorado Lake is a reservoir on the Walnut River 0.5 miles (0.80 km) northeast of El Dorado in the Flint Hills region of Kansas. Built and managed by the U.S. Army Corps of Engineers, it is used for flood control, recreation, and water supply. El Dorado State Park is located on its shore.

Glacier View Dam was proposed in 1943 on the North Fork of the Flathead River, on the western border of Glacier National Park in Montana. The 416-foot (127 m) tall dam, to be designed and constructed by the U.S. Army Corps of Engineers in the canyon between Huckleberry Mountain and Glacier View Mountain, would have flooded in excess of 10,000 acres (4,000 ha) of the park. In the face of determined opposition from the National Park Service and conservation groups, the dam was never built.
Kanopolis Lake is a reservoir in Ellsworth County in the Smoky Hills of central Kansas, about 31 miles southwest of Salina and a few miles southeast of the town of Kanopolis. The lake is formed by Kanopolis Dam. Completed in 1948 as a flood control and water conservation project of the United States Army Corps of Engineers, the dam impounds the Smoky Hill River.
