The reservoir situated on top of Scott Mountain.


In the mid-1970s seven public utility companies made plans to make a huge reservoir on top of the mountain. Unlike what happened in the case of Storm King on the Hudson River, however, against public opposition, the companies succeeded and were able to make a 225 foot deep, 650 acre reservoir. They erected a half mile long earth dam. They also built a 3.5 mile long tunnel that connects the top of the mountain to the Delaware River. The reservoir stores water that is pumped up from the Delaware River. During drought times, the water is released to downstream power plants.

In the preserve are the remains of the Cathers farmhouse and a lime kiln.

1989 (May)  -- it opened. 

Naturalists Jane Bullis and James Mershon have made the place a leading activist in environmental management..

There is a Visitors' Center located in the northeast area of the reservoir. You can hike the 5 mile perimeter of the reservoir.

5/14/2005.  Rosemary Cooney, Ceferino Santana, Sarah-David Rosenbaum, dog Sonar and I took a tour around the area.  We had a great day finding all kinds of wildflowers.  Dr. Patrick L. Cooney.

Sponsor: Torrey Club
Date: June 27, 1992
Leader: Bill Olson

This reservoir and its surrounding watershed preserves a nice representation of the habitats typical of its region. Mesic deciduous woodlands, old fields, evergreen plantations, and stream corridors were visited. Only a portion of the trails were explored.

A few of the many species of plants seen were Hairy Beardtongue (Penstemon hirsutus); Smooth-sheathed Sedge (Carex laevivaginata); Round-leaved Violet (Viola rotundifolia); Fly Poison (Amianthium muscaetoxicum); Broad-leaved Bunchflower (Melanthium hybridum); Lance-leaved Wild Licorice (Galium lanceolatum).

The weather during the trip was partly sunny, with temperatures in the 70's. There were ten participants.
