Water Temps - Heat Wave
Considering the northeast's recent heat wave; how long on average does it take a stream to warm up and stay warm? For the past few days we've had temps in the high 80's and low 90's and I've got a friend telling me that this is putting an end to trout fishing in VT/NH. I have a hard time believing this but wanted to get more information from the community. What factors will cool a stream back off?
Thanks for any info!
