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.
