Niagara River

The Niagara River flows north from Lake Erie. This is not the usual direction of flow in this part of Canada. More like a strait, than a river, the same amount of water that enters it from Lake Erie flows into Lake Ontario some 56 kilometers (35 miles) downstream.

 The elevation between the two lakes is about 326 feet (99 meters), half occuring at the Falls themselves.

The total area drained by the Niagara River is approximately 264,000 square miles (684,000 square kilometers).

The average fall from Lake Erie to the beginning of the upper Niagara Rapids is only 9 feet (2.7 meters)

At Grand Island, the Niagara River divides into the west channel, known as the Canadian or Chippawa Channel, and the east channel, known as the American or Tonawanda Channel.
