mahopac
The hamlet of Mahopac encircles picturesque 587-acre (238 ha) Lake Mahopac. It contains three islands, Fairy, Petre, and Canopus, all privately owned. Fairy Island sports multiple homes accessible via a short causeway; Petra boasts the Massaro House, a Frank Lloyd Wright-inspired residence, and a Wright-designed bungalo, the A. K. Chahroudi Cottage; Canopus is undeveloped. Boating, fishing and other water sports are permitted on the lake. Slips and support services are provided by two marinas.
Besides Lake Mahopac, other lakes within the Mahopac CDP include Kirk Lake, Lake Casse, Lake Secor, Teakettle Spout Lake, and Long Pond. Lake Mahopac is within the Croton River watershed yet not a part of the New York City water supply system's Croton Watershed. Kirk Lake, a controlled lake in that system, is both.
