Water temperature from USGS gauges (parameter 00010, provisional). “Now” is the latest reading if it is less than 48 hours old; the 7-day range uses USGS daily minimum and maximum for complete days only, and the trend compares the average daily mean of the first two and last two days (“about steady” = less than 1 °C change). °F converted by Flowcast. Temperatures are context only: they never change a river's status, and a gauge's reading applies to that spot, not the whole river. Gauges that don't measure temperature aren't listed.
Data from the U.S. Geological Survey (USGS). Readings are provisional and subject to revision. Flowcast statuses are automated comparisons with each gauge's own history, not safety ratings or fishing reports. Check local conditions, weather, regulations and closures before you go. Rivers can change quickly.
