Here is my take and report.
Day 1 Friday. Fished the Russian at the chute below the cottenwood hole. Limited out but it was a wait and catch day. Took about 3 hours. If you knew what you were doing you could catch fish. Inbetween reds I was enjoying some very fine bow fishing.
Day 2 Saturday. Walked down to the same chute. In 2 hours I saw 1 fish. Time to put the raft in. Floated down the powerline and parked on the left side just before the bend. 20 to 30 fish pushing up about every 15 minutes. Bluebird day and limit caught. Overall probably 30 fish caught in 5 hours that day. Many others hooked and not landed.
Day 3 sunday. Walked down to the chute again. DEAD. Hmmmm lets go up river. Waled way up. Lots of fish laying in all the back eddy's. 57 fish caught and limited out of course. It was a good day. There were a few people up there but it was still very very pleasent. 3 Blackies running around the upper river. 1 very nice one, 1 mid range and 1 newbie little guy. They all stayed on the other side of the bank and were just grabbing snacks out of the water and posed no threat at all.
Day 4 monday. Walked down to the physco zone for the opener. Wow the fish were stacked. 8am and all hell broke loose. 30 minutes later it was deader than a doornail. None of those fish shot up river they all turned and burned back into the Kenai green water. Lots of fish hooked in a short time but on my lightgear just nowhere to take them but no worries. i had enough. More fun watching the insanity.
