History:

2002 (November 2)  --  79.107 acres of open space, the former Hou property, in Knowlton Township, Warren County, were added to the the Division of Fish and Wildlife's Columbia Lake Wildlife Management Area, through the Green Acres Program. The property is also in close proximity to the Divison's Lunker Bass Program at Delaware Lake, a Scenic Overlook on Route 80 West maintained by the New Jersey Division of Transportation and the western trailhead of the 26 mile Paulins Kill Valley Trail.  The property comprises old fields, wetlands and upland deciduous forest within the Upper Delaware Watershed Management Area.  (Source: http://www.state.nj.us/dep/greenacres/hou.htm)


Trails:

After visiting Columbia Wildlife Management Area in the early morning, Rosemary, Carl, dog Sonar and I traveled the short distance over to Columbia Lake.  We parked along the lake and walked up and down the road making a plant list.  Then we drove farther along the road and went through a tunnel to get to another section of the lake.  At the end of the road one can see the dam and an old dam building. There is a path that continues from the dam, but it is better for pedestrians than cars.   Patrick L. Cooney
