Our friend Ed was at Hosmer Lake yesterday and reported this good report 

Glad I went! Caught a number of Brookies, most in spawn colors, and a legit 17” rainbow, all on a gold brass bead hare’s ear stripped in the channel. I changed my dropper a few times but they all took the HE on point. No luck in the lower lake at the end of day. High was 43F both air and water temps. 33F when I got there at 10, and water was 39F, but they were still biting. Saw 5 other guys on pontoons, so it was pretty damned fun. Felt like a real stillwater fisherman!

This said, at Hosmer we have some real early winter weather coming for the last week of October. Today through Sunday might be about it for the Hosmer experience until next Summer.
