It includes the 298‐acre, 35‐foot deep White Oak Pond (and islands) and its two primary drainage systems in Holderness, Ashland, and Center Harbor. The watershed forms the western part of the 28,094‐acre Squam Lake Drainage (HUC 010700010502) and lies immediately above Piper Cove on Squam Lake. The two perennial streams total 2.26 miles, with the largest one rising on the north slopes of McCrillis Hill in Center Harbor and flowing northerly, and the slightly smaller one draining an unnamed hill in the eastern corner of Ashland and flowing easterly through a large beaver marsh on Coxboro Road. The watershed is primarily forested, although ponds, wetlands and other surface waters make up a substantial portion of the area (23.8%). Forests are primarily mixed hardwoods and conifers, with an abundance of white pine and red oak that have regenerated from former pastureland. Forested wetlands make up the plurality of the hydric soils areas, where red maple swamps are the most common. Other commercially viable timber species include red spruce, eastern hemlock, sugar maple, yellow birch, beech, and white oak.
