This site includes a series of reservoirs and streams flowing south from
Mongaup Valley to the Delaware River, including the Mongaup Falls
Reservoir and the Rio Reservoir. Water releases by the Orange and
Rockland County Utilities keep the reservoirs and river from freezing
completely, thereby providing a steady food supply for wintering
eagles. NYS DEC administers the site and has built a viewing blind
for watching eagles.
Mongaup supports one of the largest concentrations of wintering
Bald Eagles in the state (numbers have exceeded 100 individuals), and
several breeding pairs.
This site is listed in the 2002 Open Space Conservation Plan as a priority
site under the project name Mongaup Valley Wildlife Management Area.
Portions of this site have been designated as a state Bird Conservation
Area. The property is not open for general public use from December
1st through March 31st; however, eagle viewing is allowed from a
blind or vehicle. Disturbance to nesting and wintering eagles should
be monitored. The reservoirs and river should be kept from freezing
completely to provide a foraging area for wintering eagles.
