Pressing this asks the USGS for the current reading. Nothing is sent but the gauge numbers.
Flow readings from USGS Water Services (public domain), cubic feet per second at the time shown; Directions opens Google Maps at the gauge; a gauge under ice or offline reads as no reading, never as a number. Stretch names are the common ones; the river descriptions, classes and access points are American Whitewater's, linked on each river.
Class definitions from Wikipedia, International scale of river difficulty (CC BY-SA 4.0), read 2026-11-05; the class of each Colorado stretch is American Whitewater's, linked; the choosing lines are ours.
