Four of the five sky lakes on the Shawangunk Ridge lie within the preserve: Lake Minnewaska, Lake Awosting, Mud Pond (also known as Lake Haseco), and Lake Maratanza; Mohonk Lake is on the property of the Mohonk Mountain House to the north of Minnewaska. Lake Minnewaska is a bit less than long by wide at its widest point. Lake Awosting is roughly three times as large, with a length of about and a maximum width of about mile.
