The river, occasionally described as a strait,[8] is approximately 58 kilometres (36 mi) long and includes Niagara Falls. Over the past 12,000 years, the falls have moved roughly 11 kilometres (6.8 mi) upstream from the Niagara Escarpment, creating a gorge below the falls. Today, the diversion of the river for electricity generation has significantly slowed the rate of erosion. The total elevation drop along the river is 99 metres (325 ft). The Niagara Gorge, downstream from the falls, includes the Niagara Whirlpool and additional rapids.
The Niagara River and its tributaries, Tonawanda Creek and the Welland River, formed part of the final section of the Erie Canal and Welland Canal. After leaving Lockport, the Erie Canal heads southwest into Tonawanda Creek. Upon entering the Niagara River, watercraft proceed south to the final lock, where a short canal section allows boats to bypass turbulentshoal water and enter Lake Erie. The Welland Canals used the Welland River to connect to the Niagara River south of the falls, enabling water traffic to safely re-enter the river and continue to Lake Erie.
History
The Niagara River and Falls have been known outside of North America since the late 17th century, when Father Louis Hennepin, a French explorer, first witnessed them. He wrote about his travels in A New Discovery of a Vast Country in America (1698).[9]
The Niagara River was the site of the earliest recorded railway in America. It was an inclined wooden tramway built by John Montresor (1736–1799), a British military engineer, in 1764. Called "The Cradles" and "The Old Lewiston Incline", it featured loaded carts pulled up wooden rails by rope. It facilitated the movement of goods over the Niagara Escarpment in present-day Lewiston, New York.[10]
In 1781, the Niagara Purchase was signed, involving a 6.5-kilometre-wide (4.0 mi) strip of land bordering the west bank of the Niagara River, connecting Lake Erie and Lake Ontario.[11]
The river was an important route to liberation before the American Civil War, as many African-Americans escaping slavery on the Underground Railroad crossed it to find freedom in Canada. The Freedom Crossing Monument stands on the bank of the river in Lewiston to commemorate the courage of the escaping slaves and the local volunteers who helped them secretly cross the river.
In the 1880s, the Niagara River became the first waterway in the world harnessed for large-scale generation of hydroelectricity.[12][13]
On the Canadian side of the river the provincial agency Niagara Parks Commission maintains all of the shoreline property, including Fort Erie, except the sites of Fort George (a National Historic Site maintained federally by Parks Canada), as a public greenspace and environmental heritage.
The Niagara River has a long history of both road and rail bridges spanning the river, both upstream and downstream of the Falls. This history includes numerous bridges that have fallen victim to the harsh conditions of the Niagara Gorge, such as landslides and icepacks.
Parks
The following parks are located along the Niagara River:
Black Rock Canal flows within and parallel to the east shore of the Niagara river near Buffalo, New York, and was built to extend the navigation period in the Niagara River through a greater part of the winter.[15] The canal begins at Buffalo Harbor, on the north-east shore of Lake Erie, then flows north, ending at the Black Rock Lock near the north tip of Unity Island. The canal is buffered from the Niagara River by Bird Island Pier at its south end, and Unity Island at its north end.
The north-flowing Niagara River bifurcates at the south tip of Grand Island (both sections rejoin at the north tip). "Chippawa Channel" is the river passage on the west side of Grand Island.
When the Niagara River bifurcates at Grand Island, the east passage—from the south tip of Grand Island, to a point just north of Tonawanda, New York—is the "Tonawanda Channel".
When the Niagara River bifurcates at Grand Island, the east passage—from a point just north of Tonawanda, New York, to the north tip of Grand Island—is the "Niagara River Channel".
Historic tributary. Became a man-made distributary—from the Niagara River to a point 5 km west—in order to supply water to an intake channel for Sir Adam Beck Hydroelectric Power Stations.
Located between the Canadian mainland and Goat Island, New York, the Horseshoe Falls is the largest, and most south-western of three parallel waterfalls over which the Niagara River flows. There is dispute as to whether the Horseshoe Falls lies entirely within Canada (see Niagara Falls#History).
Located between Goat Island and Luna Island, Bridal Veil Falls is the smallest (and middle) of the three parallel waterfalls over which the Niagara River flows. It is entirely within the US.
Located between Luna Island and the New York mainland, the American Falls is the most northern and second largest of three parallel waterfalls over which the Niagara River flows. It is located entirely within the US.
Historic tributary which entered the Niagara River as a waterfall from the top of the Niagara Gorge. Development above Muddy Run Falls destroyed its water supply.
Tributary which enters the Niagara River as a waterfall from the top of the Niagara Gorge. The volume was greatly diminished following construction of the canal to Sir Adam Beck Hydroelectric Power Stations.

Tributary which enters the Niagara River as a waterfall from the top of the Niagara Gorge. The volume was greatly diminished following construction of Robert Moses State Parkway and other streets above the falls.
Tributary which enters the Niagara River as a waterfall from the top of the Niagara Gorge. The volume was greatly diminished following the construction of Sir Adam Beck Hydroelectric Power Stations.
Historic tributary which entered the Niagara River as a cascade from caves in the wall of the Niagara Gorge. Its source was destroyed following construction of the Niagara Power Project.

Also known in some sources as "Coroner Island".[19] Filled in sometime in the 1950s or early '60s.[20][21] Currently the site of the Niagara Power Station Intake.[22]
Located at the brink of the American Falls, named by John Stedman in the 1770s; briefly renamed to Iris Island by General Augustus Porter, a United States Commissioner (after the Greek Goddess of the Rainbow). Now part of Niagara Falls State Park.
Was located at the confluence of Tonawanda Creek and the Tonawanda Channel of the Niagara River. Existed from 1825, when the Erie Canal was constructed (thereby cutting Goose Island off from the mainland) until the 1940s, when this portion of the canal was filled in.
The largest island on the river; includes several parks, but is mostly residential and industrial; originally called Ga-We-Not (Great Island) by the Seneca.
Filled in by the creation of the Chippawa Queenston Power Canal in 1917 and finally by the Sir Adam Beck Dam #2 in 1950 by the Hydro Electric Power Commission of Ontario.
Also known as Pirates' Island (the name of a private club once located there) and Frog Island (not to be confused with the former Frog Island listed below).[23] A New York State Wildlife Management Area.
Was located just south of what is today the South Grand Island Bridge. Was filled in sometime between 1915[24] and 1927,[25] concurrent with the heavy industrial development of the area.
Shown in the 1908 New Century Atlas of Niagara and Orleans County but not mentioned in any other source.[22] Supposedly located just offshore from the mouth of Gill Creek.[19] No longer extant, if it ever was.
Originally known as Frog Island; was located in the Upper Niagara River between Motor and Strawberry Islands; disappeared sometime between 1951 and 1985 due to erosion.[28] Re-created as a habitat for fish, aquatic plants, and waterfowl[29][30] including a nesting colony of common terns established in 2021, for whom the new island was named.[31]
On the Canadian side the Niagara Parkway travels along the River from Lake Ontario to Lake Erie.
NY 18F lines the river on the state side from Fort Niagara to Lewiston. Niagara Scenic Parkway on the state side only travels along the River from the Falls to Lewiston. The remaining river sections (with some interruptions) are covered by the LaSalle Expressway, NY 384, NY 266 and I-190 (Niagara Thruway) / New York Thruway.
