Over all the years I have been fishing/guiding on the lake, anytime the Corps is letting out water for an extended amount of time, the larger koke's start traveling up the lake. When the dam gets shut off they come back down. Currently most of them are Reed's Cr and above. From what I have experienced, water temp doesn't mean much. That lake down 30' has a pretty stable temp reading year around. What I think happens is when they let water out it creates current. Salmonoids have what is called Positive Riotaxis. When they feel current they swim into it. few years back IDFG tagged some Koke's. They traveled 20 miles in 2 days when the Corps was letting out water. they were netted both times. 1 for tagging and a second for indexing. Idfg was shocked they traveled that much. They aren't going to be overly large this season...... 10" will be a good one.
My advice: Hang in there, they will be back and ready to Play! Good Luck out there and Be Safe!
