Taking the Measure of the Estuary
The Hudson flows 315 miles from Lake Tear of the Clouds in the Adirondacks to the Upper Bay of New York Harbor. It is an estuary for the 153 miles from Troy to the Bay, which extends another seven miles to the Narrows and the Verrazano-Narrows Bridge between Brooklyn and Staten Island.
The Hudson’s width ranges from about 500 feet at Troy to three and a half miles at Haverstraw. It is deepest at West Point—216 feet according to a 1934 survey. Depths change with the tides; water levels at high tide are three to five feet above the low tide levels.
