Outside temperatures are going to stay in the mid to low 60s. with lows near 40. We are expecting stable weather through the week. It feels like fall is creeping in! Caddis are still around with good hatches later in the day and the terrestrials are abundant as temps warm up mid day.

Techniques & Tips as of 9/21/23

Purple Chubby patterns and flashy prince nymphs as indicators. Downsize to a Purple Haze Ant pattern and beetles are producing well.
