Congrats on the good fishing. I'm an El Do regular and I haven't had near that kind of luck as of late. I usually fish the small lake, north of the big one because there's too much traffic at the big lake.
For the life of me, I can't get bit on a senko. I even throw the same color as you and I use a 3/0 hook - but the same brand and style as yours. I've fished every possible spot on both lakes (but again, I spend most of my time on the small lake). I've also yet to see anyone else catch fish of late when I'm there.
Sunday I caught one small fish on a shallow running crank bait and ran into a ranger who said some guy caught a 5lb 2 ounce fish on a spinner bait.
The big lake is really getting huge mats along the shore and the water is looking pretty disgusting these days. People are starting to catch bluegill at the big lake. The small lake's water is much more clear, but just as weedy.
