Lake Innisfree

The area surrounding the lake was once rolling woodland owned in large sections by farmers in the 1700-1800s. The New Rochelle Water Company then bought up the land using it as a watershed for the lake served as the water supply source for Upper Rochelle during the late 19th and early 20th centuries.

Constructed in 1885,^[2] the reservoir is impounded by the New Rochelle Reservoir No. 1 Dam on the Hutchinson River. The dam is masonry and of earthen construction, with a height of 34 ft (10 m) and a length of 680 ft (210 m). The water surface covers an area of about 65 acres (26 ha) and the capacity is about 271.7 million US gallons (1,028,000 m³). It has a maximum discharge of 744 cubic feet (21.1 m³) per second and drains an area of 2.2 square miles (5.7 km²).^[3]

The water from this reservoir flows by gravity to the southern, low level district of the city. There is a steel equalizing tank 34 ft (10 m) high by 44 ft (13 m) in diameter connected with this system on high ground 2 miles (3.2 km) south of the dam.^[3] The dam, which impounded 300 million gallons of water, cost $60,000 to build. While at first, the water supplied New Rochelle exclusively, two additional dams were constructed so that the water could also be routed to Pelham, Eastchester, and elsewhere.^[2]

The reservoir was named Lake Innisfree in the 1930s by the developer of the adjacent Interlaken Cooperative. The same developer constructed a sandy beach for recreation.^[4]

In 2022, Eastchester took ownership of the central portion of the lake's dam.^[5]
