General Information
Mature trout will be spawning soon so keep an eye out for redds and give those fish a break.
Flow bands and temperature bands are TCO's own calibration from years on this water, not a USGS product. The 68° line is a conservation threshold, not our opinion. Gauge data courtesy of the U.S. Geological Survey.
