The original Boonton is at the bottom of a reservoir.
Old Boonton sat on the Rockaway River about a mile and a half downstream from today's town, and its ironworks made supplies for the Patriot Army. In 1899, Jersey City contracted for a water supply from the river. The village's buildings were torn down or moved, the valley was flooded, and water started reaching Jersey City in 1904.
That's the Boonton Reservoir in Parsippany today, about 800 acres. In the droughts of 1957 and 1980, the water dropped low enough to show old foundations and stone walls.
Did you know a whole village was under there?
