Cassadaga (a Seneca Indian word meaning "water beneath the rocks") is a village in Chautauqua County, New York, United States.

[2] Cassadaga is a Seneca name meaning "water under the rocks", descriptive of the natural springs of the area flowing from glacial moraines.

They gradually migrated westward as this territory was opened up for settlement after the Seneca people and other Iroquois League tribes had been forced out of the state after the war.

Early settlers harvested the abundant and large trees (some exceeding 5 feet (1.5 m) in diameter) as a primary source of income.

They shipped them downstream to markets via log rafts and flatboats on the creek as timber, charcoal and pearl ash, the latter two products in demand in the early Industrial Age.

The Webster Citizens Company ice house stood on the west shore of the Upper Lake, with a three-car rail siding to serve it, and was listed as a railroad business as late as 1931.

Cassadaga is located on the northwestern edge of the Allegheny Plateau in western New York at 42°20'29" north, 79°18'56" west (42.341343, -79.315653)[3] at an elevation of approximately 1,340 feet (410 m) above sea level.

[4] The soils are glacial in nature, ranging from deep gravel loams in the valleys to heavy clays on the hill tops.

Springs are fairly common, though somewhat high in mineral content (calcium, sulphur and iron, depending greatly on location).

The village and environs are served by a volunteer fire department and ambulance squad, and are part of the County Mutual Aid Plan.

The Cassadaga Lakes contain a variety of fish including bass, carp, crappie, muskellunge, northern pike, perch, trout and walleye.

There is a walking / jogging path around the lower and middle lakes (on the road shoulders) that is about 3 miles (5 km) in length.

There is a public beach on the southeast side of the lower lake off Park Avenue in the village that is generally open from mid June (when the water warms sufficiently) until Labor Day, that has a lifeguard on duty and is free for all.
