Lake Innisfree (also known as Lake Isle or Interlaken, and originally as Reservoir No. 1) is a man-made lake and former reservoir in the city of New Rochelle and the town of Eastchester, in Westchester County, New York. Its eastern end abuts the Hutchinson River Parkway. The lake takes its name from the poem Lake Isle of Innisfree by W. B. Yeats.
