Croton Falls Reservoir, New York
A reservoir in Westchester County, New York, located within the broader Hudson Valley region. In the UAP context, it is the site of a 1993 triangular UAP sighting by witness Jim Cook, occurring during the Hudson Valley UFO flap — a prolonged wave of large structured craft sightings documented across New York and Connecticut from the early 1980s through the mid-1990s.
The 1993 Jim Cook Sighting
In 1993, Jim Cook observed a large triangular UAP over or near the Croton Falls Reservoir. The sighting occurred during the latter phase of the Hudson Valley flap, a period characterized by mass witness events involving slow-moving boomerang or V-shaped objects with multiple lights. Cook's encounter contributed to the documented record of triangular craft appearances in the Hudson Valley corridor.
The Hudson Valley Flap
The Hudson Valley UFO flap is one of the most extensively documented regional UAP waves in American history. Hundreds of witnesses — including police officers, civilian pilots, and IBM engineers — reported seeing large, silent, low-flying structured objects throughout Westchester and Dutchess counties in New York. The Croton Falls Reservoir and surrounding reservoir system in the lower Hudson Valley became focal points for sightings due to the area's dark skies and low population density. Researchers J. Allen Hynek, Philip Imbrogno, and Bob Pratt compiled witness testimonies in the 1987 book Night Siege.
