Live flow, gage height, and water temperature from wy-water on top of the USGS instantaneous service. Scan tonight's board, click a sensor on the map, then walk the corridor upstream toward the lakes or down toward Big Piney.
As of Fri, Sep 18, 12:37 PM Mountain Time. 13 live, 3 quiet, 16 public gages. Values are USGS provisional. A cubic foot per second is about 7.5 gallons every second — not a wading depth.

Sensor map
Dots are USGS coordinates. Size is live flow against the largest live gage on this map — volume, not a wading depth. Thin lines join gages on the same river in catalog order, headwaters toward the valley — not a surveyed channel.
Upstream → downstream
Same river, in order. Bar length is tonight's live flow against the largest live gage here — not how wadable the water is.
