Sandyfield, New York

Sandyfield was a settlement of about 30 houses in the Town of Ramapo in Rockland County, New York, United States, that was submerged in 1928 when swampy Beaver Pond was dammed to create Lake Welch in Harriman State Park.

By 1942, the lake was completed using workers from the Civilian Conservation Corps that was building the park.

Every winter, the lake is drained about 20 feet to reclaim sand lost to the water.

The beach can be accessed from Exit 16 on the Palisades Interstate Parkway via Lake Welch Drive (closed winters) or County Route 106.

Adjacent to the lake is Beaver Pond Campground, one of two state-run overnight areas in the park.
