Hudson River

River · New York

Flowing 315 miles from the Adirondack Mountains to New York Bay, the Hudson River is one of America's most historically significant waterways. The river occupies a glacially-carved fjord, with tidal effects reaching 153 miles north to Troy. Indigenous peoples called it Mahicannittuk — "river that flows two ways." Henry Hudson explored it in 1609, and the Erie Canal made it a vital 19th-century artery. The river inspired the Hudson River School of landscape painting and remains a premier destination for fishing, kayaking, and sailing.

About this map

Every pin is a live reading from a USGS real-time monitoring station, captured in a daily snapshot. Colours follow the site’s cold-water-safety thresholds and describe the water at that one sensor — usually a river or stream gauge, not a swim beach — so treat them as a guide to what the water is doing nearby, not a verdict on a specific spot. Readings are provisional and can be revised by the USGS. Your location only sorts this page: the coordinates appear in the address bar (rounded to about a mile) and are not saved to an account or our database.

Conditions are for general information only and can change quickly. Always judge the water in person and follow posted advisories and local guidance before swimming or paddling.
