The Ohio River is a 981-mile (1,579 km) long river in the United States. It is located at the boundary of the Midwestern and Southern United States, flowing southwesterly from far-western Pennsylvania south of Lake Erie to its mouth on the Mississippi River at the southern tip of Illinois. It is the third largest river by discharge volume in the United States and the largest tributary by volume of the north-south flowing Mississippi River that divides the eastern from western United States. The river flows through or along the border of six states, and its drainage basin includes parts of 14 states. Through its largest tributary, the Tennessee River, the basin includes several states of the southeastern U.S. It is the source of drinking water for three million people.
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.
The Falls of the Ohio National Wildlife Conservation Area is a national, bi-state area on the Ohio River near Louisville, Kentucky in the United States, administered by the U.S. Army Corps of Engineers. Federal status was awarded in 1981. The falls were designated a National Natural Landmark in 1966.
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.
Ford Dam, officially known as Lock and Dam No. 1, is on the Upper Mississippi River and is located between Minneapolis and Saint Paul, Minnesota just north of the confluence of the Mississippi with the Minnesota River at Mississippi River mile 847.9, in Minneapolis. The powerhouse portion was previously owned by the Ford Motor Company, which operated a hydroelectric power station to feed electricity to its Twin Cities Assembly Plant on the east side of the river. It was sold to Brookfield Power Co. in April 2008. The dual-lock facility and dam was built and is operated by the St. Paul district of the U.S. Army Corps of Engineers' Mississippi Valley Division.
Kentucky Dam is a hydroelectric dam on the Tennessee River on the county line between Livingston and Marshall counties in the U.S. state of Kentucky. The dam is the lowermost of nine dams on the river owned and operated by the Tennessee Valley Authority, which built the dam in the late 1930s and early 1940s to improve navigation on the lower part of the river and reduce flooding on the lower Ohio and Mississippi rivers. It was a major project initiated during the New Deal of President Franklin D. Roosevelt's administration, to invest in infrastructure to benefit the country. The dam impounds the Kentucky Lake of 160,000 acres (65,000 ha), which is the largest of TVA's reservoirs and the largest artificial lake by area in the Eastern United States. It was designated as an National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1996 and listed on the National Register of Historic Places in 2017.
The John T. Myers Locks and Dam is the 17th Lock and dam on the Ohio River located 846 miles downstream of Pittsburgh about 3 miles (4.8 km) downstream from Uniontown, Kentucky. There are two locks, one for commercial barge traffic that is 1,200 feet long by 110 feet wide, and the auxiliary lock is 600 feet long by 110 feet wide. This United States Army Corps of Engineers facility is in Posey County, Indiana, and Union County, Kentucky. The project was authorized as replacement for existing Locks and Dam 48 and 49 on September 17, 1958, by Secretary of the Army under authority of Section 6 of the Rivers and Harbors Act approved March 3, 1909, as amended.
The Louisville and Portland Canal was a 2-mile (3.2 km) canal bypassing the Falls of the Ohio River at Louisville, Kentucky. The Falls form the only barrier to navigation between the origin of the Ohio at Pittsburgh and the port of New Orleans on the Gulf of Mexico; circumventing them was long a goal for Pennsylvanian and Cincinnatian merchants. The canal opened in 1830 as the private Louisville and Portland Canal Company but was gradually bought out during the 19th century by the federal government, which had invested heavily in its construction, maintenance, and improvement.
The Cannelton Locks and Dam is a tainter-gated dam with two locks on the Ohio River, on the border between the U.S. states of Indiana and Kentucky. The dam is 2 miles (3.2 km) southeast of Cannelton, Indiana. Construction of the locks began in July 1963. The locks began operation in December 1966 and were completed April 1967. Construction on the dam started in August 1965 and the dam was completed in 1974. The structure was designed, built, and is operated by the United States Army Corps of Engineers Louisville District.
The Olmsted Locks and Dam is a locks and wicket dam on the Ohio River at river mile 964.4. The project is intended to reduce tow and barge delays by replacing the existing older, and frequently congested, locks and dams Number 52 and Number 53. The locks are located about 17 miles upstream from the confluence of the Ohio and Mississippi rivers at Olmsted, Illinois.
Ohio Falls Station is a hydroelectric power station owned by Louisville Gas & Electric (LG&E) and Kentucky Utilities (KU) which is located three miles west of Downtown Louisville, Kentucky. The generating station is located on Shippingport Island at the site of the McAlpine Dam and locks along the Ohio River in Kentucky. The plant was built in 1923 by Byllesby Engineering and Management Corporation and the U.S. Army Corps of Engineers. The plant featured eight 10.4 MW units operating at roughly 13,500 hp per unit. Each unit was composed of Allis Chamber turbines and General Electric generators. The plant is located inside the Ohio Natural Wildlife Conservation Area and is considered a large impoundment hydro power plant. The station was built after a canal and dam within the Ohio river in an attempt to allow boats to navigate the 8 ft vertical drop among the falls that spanned 2 miles wide. Production of the canal and dam began in 1825. It was not until a repair on the dam was needed that Louisville engineers had the idea of building a hydroelectric station to harvest the power of the falls.
Belleville Lock and Dam is the 8th Lock and dam on the Ohio River, located 204 miles downstream of Pittsburgh. There are two locks, one for commercial barge traffic that's 1,200 feet long by 110 feet wide, and the auxiliary lock is 600 feet long by 110 feet wide.
Greenup Lock and Dam is the 11th Lock and dam on the Ohio River, located 341 miles downstream of Pittsburgh. There are 2 locks, one for commercial barge traffic that's 1,200 feet long by 110 feet wide, and the auxiliary lock is 600 feet long by 110 feet wide.
Newburgh Lock and Dam is the 16th lock and dam on the Ohio River, located 776 miles (1,249 km) down stream of Pittsburgh.There are two locks. The main lock for commercial barge traffic that is 1,200 feet (370 m) long by 110 feet (34 m) wide, and the auxiliary lock is 600 feet (180 m) by 110 feet (34 m) wide.
Smithland Lock and Dam is the 18th lock and dam on the Ohio River, 919 miles down stream of Pittsburgh and 63 miles upstream from the confluence of the Mississippi with the Ohio. There are 2 locks for commercial barge traffic that are 1,200 feet long by 110 feet wide.
Lock and Dam 52 was the 19th lock and dam on the Ohio River. It is 939 miles downstream of Pittsburgh and 23 miles upstream from the confluence of the Mississippi with the Ohio.
Lock and Dam 53 was the 20th lock and dam upstream from the confluence of the Ohio River and the Mississippi River. It was located 962 miles downstream from Pittsburgh. Lock and Dam 53 had two locks for commercial barge traffic, one that was 1,200 feet long by 110 feet wide, the other 600 feet long by 110 feet wide. The lock will be demolished and Olmsted Lock and Dam will replace it.
