The Sprouts of the Mohawk River are the multiple channels of the Mohawk River as it flows into the Hudson River creating a delta in the US state of New York. Most of the sprouts lie within Albany County, with the northern ones in Saratoga County, and the sprouts enter the Hudson at the boundary with Rensselaer County. The islands formed by the sprouts are, from north to south–Peebles Island, Polrump Island, Bock Island, Goat Island, Second Island,Van Schaick Island, Simmons Island. and formerly Green Island. The sprout separating Green Island from the rest of Albany County was filled in with the creation of Interstate 787 and NY Route 787.
Henry Hudson's crew may have reached as far as the sprouts in 1609 when Hudson sent a small boat with his first mate and four crew members from Half Moon up the Hudson River to see if the river was indeed the Northwest Passage. The islands and sprouts (spuyten in Dutch) along with land along the northern shore of the northern sprouts was part of a tract of land deeded to Philip Pieterse Schuyler and Gozen Gerritse Van Schaick in 1665. The Native Americans called the area Nach-te-Nack, and by the Dutch settlers Halve-Maen (translated as Halfmoon in English). In 1674 Schuyler gave up his rights to the land to Van Schaick, and in 1687 Van Schaick's son Anthony Van Schaick was confirmed sole owner through patent title by Governor Thomas Dongan.
