Sawmill River, Yonkers

Around 1650, long before Yonkers was established as a city and well
before New York became New York, a Dutch lawyer and landowner named
Adriaen van der Donck built a water-powered sawmill on Nepperhan Creek,
near the spot where that creek flowed out into Hudson River. That
sawmill became the center of a growing town on van der Donck’s land.
Eventually the town become known as Yonkers, a name that was derived
from van der Donck’s Dutch honorific “Jonkheer” (which roughly
translates as “gentleman" or "squire”).

The sawmill that Van der
Donck built also gave a new name to Nepperhan Creek, and it has known
as the Sawmill River ever since. The Sawmill is the Hudson’s longest
tributary, at 23 miles long, but it is still a fairly small river, and
as Yonkers grew, it grew around and over the small river. As more
industrial and residential buildings were built in the 19th century,
some straddled the river. Sections of it were shunted through
underground flumes, and road bridges were built across other parts of
it, until eventually the city decided to simply cover over the last
exposed sections of the river. By the early 1900s, the river was
completely underground for the half-mile section that passes through
downtown Yonkers.
