That would be the Hudson River in New York state. These pictures were taken in Poughkeepsie while enjoying the Walkway Over the Hudson experience.
According to the Department of Environmental Conservation:
‘The Hudson estuary stretches 153 miles from Troy to New York Harbor, nearly half the river’s 315 mile course between Lake Tear of the Clouds in the Adirondacks and the Battery at the tip of Manhattan. The estuary feels the ocean’s tidal pulse all the way to Troy. Push a stick into the beach at the water’s edge, or note the water’s height on a piling or rock. Check back in 20 minutes. Is the water level the same? The estuary usually has two high and two low tides in twenty-four hours. With this rise and fall come changes in the direction of flow. In general, a rising tide is accompanied by a flood current flowing north towards Troy, a falling tide by an ebb current flowing seaward.’ You can read entire article by CLICKING HERE https://www.dec.ny.gov/lands/4923.html
