Green River (Kentucky)
The Green River is a 384-mile-long (618 km) tributary of the Ohio River that rises in Lincoln County in south-central Kentucky. Tributaries of the Green River include the Barren River, the Nolin River, the Pond River and the Rough River. The river was named after Nathanael Greene, a general of the American Revolutionary War.

Following the Revolutionary War, many veterans staked claims along the Green River as payment for their military service. The river valley also attracted a number of vagrants, earning it the dubious nickname Rogue's Harbor.
In 1842, the Green River was canalized, with a series of locks and dams being built to create a navigable channel as far inland as Bowling Green, Kentucky. Four locks and dams were constructed on the Green River, and one lock and dam was built on the Barren River, a tributary that passed through Bowling Green.
In 1901, two additional locks and dams were opened on the Green River, which allowed river traffic to Mammoth Cave. In 1941, Mammoth Cave National Park was established, and the two upper locks and dams closed in 1950. In 1965, Lock and Dam #4 at Woodbury failed; this was the dam that locked both the Green and Barren rivers.
In 1969, the United States Army Corps of Engineers impounded a section of the river, forming 8,200-acre (33 km2) Green River Lake. The lake is now the primary feature of Green River Lake State Park.
There is still one Native American tribe living on the Green River: the Southern Cherokee Nation of Kentucky. In 1893 Governor John Y. Brown (1835–1904) recognized the Southern Cherokee Nation as an Indian tribe.

The Green River flows through Mammoth Cave National Park, located along river miles 190 to 205. The river drains the cave and controls the master base level of the Mammoth Cave system: the construction of a 9-foot (2.7 m) dam at Brownsville in 1906 has raised the water level in some parts of the cave system by as much as 6 feet (1.8 m) above its natural value.
The 384-mile-long (618 km) Green River, an important transportation artery for the coal industry, is open to traffic up to the closed Lock and Dam #3 (known as the Rochester Dam) at mile 108.5. Muhlenberg County, once the largest coal-producing county in the nation, benefits greatly from access to the river, as does the aluminium industry in Henderson County. In 2002, more than 10 million short tons were shipped on the river, primarily sub-bituminous coal, petroleum coke, and aluminium ore.
The river rises from Kings Mountain, Kentucky and follows a meandering path, collecting several smaller streams along its way to its impoundment by a dam at Green River Lake near Campbellsville. It then continues in a westerly direction and is joined by the Little Barren River before entering the Mammoth Cave National Park. After it exits the park, it receives the tributary of the Nolin River which exits Nolin Lake. Then continuing westward it is joined by the Barren River. It then takes a more northwesterly turn as it proceeds through western Kentucky. Near Sebree it provides coolant water for Robert Reed Power Station, a coal fired power plant, before it finally empties into the Ohio River at Evansville, Indiana.
