From an old fly fishing buddy:
I was looking at the Forum posts regarding the Klamath. Other things folks, especially walk and wade anglers, should check beforehand is the level of fine particles (eg PM 2.5) via the AQI and for access closures. For example, if I read a USFS announcement correctly, most of the US Forest Service lands above Weitchpec up to Somes Bar is currently closed due to the wildfires. This might not affect anglers on floats, but could certainly impact walk-in anglers."
