Tonawanda Creek is a small tributary of the Niagara River in Western New York, United States. After rising in Wyoming County, the stream flows through Genesee County before forming part of the boundary between Erie County and Niagara County.
The length of Tonawanda Creek is 90 miles (140 km). Its drainage basin is nearly 650 square miles (1,700 km2) in area. It flows on a meandering course for most of its length, first northerly until reaching the City of Batavia where a sweeping bend takes it westerly.
Tonawanda Creek rises in Wyoming County and enters the Niagara River between Niagara County and Erie County, forming a boundary between them. Tonawanda Creek passes through the Village of Attica, the City of Batavia, flows between the City of North Tonawanda to its north and the Town of Amherst to its south, the Town of Clarence, the Town of Tonawanda, and the City of Tonawanda. Just after being joined by Ellicott Creek, it enters the Niagara River.
During the spring of each year, some sections of Tonawanda Creek flood to varying degrees. These floods are more of an inconvenience than a danger, but can be more serious, especially when ice jams dam up the water. The larger flooding can cause property damage.
Tonawanda Creek is also part of the Erie Canal, which joins the creek southwest of Lockport and allows canal traffic to proceed into the Niagara River. In its upper reaches, Tonawanda Creek and the Little Tonawanda, which is tributary, are trout streams.
Tonawanda Creek flows through the ancient lake bed of Glacial Lake Tonawanda, a prehistoric lake that existed approximately 10,000 years ago at the end of the last ice age; many of the swamp lands surrounding Tonawanda Creek also date back to this lake.
When the Erie Canal was first built, the Tonawanda Creek was the source of water for the western section of the Canal.
