5-Day Outlook as of 9/22/22

It's going to be a hot week. I cannot predict how quickly stream temps will rise from the low 60's to the high 60's. Bring your thermometer and make sure to cut off catch and release fishing around 68 degrees. The week starts hot getting cooler by the weekend. Monday or Tuesday will probably hit bad water temps for C&R Trout fishing.
