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.
