Hi guys, I'm a newbie on your board and hope someone will give me their opinion. I haven't been salmon fishing on the O for a few years now but we will be camping this weekend and want to take a day to try it again. With this cold front passing through the air temps are supposed to be 70 on Th, 75 Fri, and low 80's for Sat-Sun. On the smaller waters I fish Sunday would probably be a better bet since the weather had more time to stabilize but I'm not sure that it's the same on the big water. So if you only had 1 day to fish would it be Sat. or Sun.? Thanks in advance for any replies.
