 In the 1880s, the City faced increasing demands for water and therefore needed to enlarge the Croton Reservoir to meet that need.The enlargement of the Croton Reservoir (with the construction of the New Croton Dam and the forming of the New Croton Reservoir) was completed in 1906 as a part of a system of reservoirs designed to bring water from Putnam and Westchester Counties (the Croton Watershed) to New York City.The village of Kensico, NY was named in 1849 for a Siwanoy Indian chief, Cokenseko, who had sold most of the land surrounding White Plains to English settlers in the 1600s.
