Summer is here early, and with a vengeance. The good news is that we have solid summer flows coming out of the dam at a favorable temperature:

However, note that the water temperature spikes five degrees by late afternoon, just from the release of the dam down to the measuring point at the bridge in Riverton. It doesn’t take a math whiz to reckon that once the river reaches Collinsville, the water is going to be significantly warmer.

This is where you and a good water temperature thermometer come in. If you don’t have one, you should get one. (I use this IR wine thermometer, $30 from Amazon). There is some debate about what the cutoff temperature for fishing is; 67-68 seems to be the number. My present policy is to call it at 67; that is, if it’s 67 or higher, I won’t fish for trout.

Also note that evening, night, and early morning are going to be your best times for find favorable temperatures; what’s more, those coincide with low light periods, which are generally good times to fish.

Finally, this time of year sees explosive feeding activity, starting around 7:30pm and building exponentially into dark. Don’t make the mistake of leaving the water at 8:15pm. You’ll be missing the best dry fly fishing of the day.
