OK, this report would not be believed if I gave you the truth, so I'll tone it down a bit. Two of us found the fish, a lot of fish, and we did well most of the day. But, based on reports from the launch, we were the only ones. OK, we did see one boat, one guy, that claimed to be doing pretty well, but he was fishing our old water behind us and I never saw him with a fish, so I don't know for sure.
We, however, knocked them dead. Rock Lake is really a technique specific lake. It is more about what you use, fed to the fish where they concentrate, at the times they concentrate there. Spot A may not turn out fish in the afternoon, while Spot B may not turn out fish in the morning. Method 1 may work on Spot C, while Method 2 will only work on Spot D. Our average fish was about 3 pounds, my partner getting one about 4.5 pounds. I warn you, I think every fish in the lake has a sore jaw right now, so don't expect to duplicate it for a while (LOL). Yes, we lost at least as many as we caught.
The water was still pretty dirty, and the inflow is still quite high. I estimate the visibility at still less then 2' right now. It is dirtier at the inlet, but only slightly less so at the outlet. The water temperature was 46 degrees at the inlet, but only about 42 at the outlet. I did find one tiny cove with a water temperature of 50 degrees, and I can't explain it. The amount of water coming into that spot was too small to make that kind of difference, unless it is a hot springs, and I don't think we have hot springs in Eastern Washington. The water level is stable at about 6 or 7 inches below the high water mark of the year. The snow is gone in the Rock Creek Drainage, so the water we are getting must be excess ground water. IF this is so, and with the amount of inflow we still have, it could be some time before the mud stops coming into the lake.
