I've noticed that on one or two of the few USGS gauges that show temps, there have been dips into the upper 50's. Temps after a cool night or two should be fine on most wild trout streams. Just watch the forecast. Warm days with warm nights are not conducive to good fishing. We're in a time of year when temps are going to make pretty big swings over the course of the day and from day to day. The fishing can be inconsistent but I think the fish are through the worst of it, as long as the rain keeps coming. Streams are in better shape than the past few years but it's still low and clear summer/fall conditions. The rain comes but most creeks drop and clear pretty quick still. As long as there's green vegetation, we need the rain to keep up.
