William Clough Nature Preserve
Putnam County, NY
Patterson Environmental Park/Great Swamp
58 acres


Directions:

Take Route 22 and turn west (left) onto Route 312 for 1.8 miles to the traffic light. Turn north (right) onto Farm-to-Market Road. Proceed 0.8 mile and turn left into preserve entrance across from a house (before Indian Hill Road). The entrance, usually noted with a wooden sign, is a single lane pull-off, with parking for 4 to 5 cars immediately on the left.


History:

This preserve was donated to the Town of Patterson in 1973 by The Nature Conservancy.


Trails:

There is a trail network. It goes from the parking area and branches into two major trails leading to the 46 acre Ice Pond. This is located in the "Towners Arm" of the Great Swamp. The left-hand trail goes through the woods. The right-hand trail skirts a wetland. Both trails rejoin just prior to the railroad tracks at the Ice Pond. The walk takes from 1 to 2 hours.

Ice Pond is a fairly big lake surrounded on three sides by mountains with a marsh area extending to the east like a big marshy finger. The railroad tracks run parallel to the eastern shore of Ice Pond. There are signs on the pond side saying "Private Property."

Saw quite a few trees with signs of beaver gnawing.

No canoe access.
