Lake Washington is deep enough that the bottom most layer of water will take up the majority of the water column. Above that layer is a band of water where the temps rise gradually the closer you get to the primary thermocline and is where I find most of my action in the Summer months. I can't say for sure what causes it, I believe it has to do with the depth that sunlight can reach in the lake. I haven't really given the lower one much attention as it is usually where the oxygen levels drop dramatically and I wouldn't expect the trout to hang out there. I guess it is early enough in the season that the O2 levels are still good throughout the entire water column. Thinking about it though, sockeye are caught at 90' during the dead of Summer so the conditions can't be all that bad at that depth.

Need to figure out what to replace it with. Try fishing just 1 day without your fish-finder, it's like driving with a blindfold on!!
