Wow! This is really going to be a problem for my father-in-law. He planned his honeymoon over the next three weeks around fishing in Yellowstone. Ohh well, he is still going to get to fish some great rivers in New Mexico and Colorado.
Great news for the fish. Its just amazing that snow-pack fed Western streams are maxing out at such high temps. Not completely surprising considering how hot it has been out there lately, daily temps on my Idaho trip were on average 100-105. Also, aside from the lack of rain they had a poor snow-pack in some areas this year.
