I grew up on Success Lake, but don't get up there much any more. My dad practically fishes it everyday and I talked to him a few days ago and he said the lake was nearly at full pool and the bite had been really tough the past few days. The lake has two inlet river systems (North and South Fork Tule River) If you are going to float tube, you might want to consider try starting near the highway bridge and working East into the South Fork of the river. Lots and lots of trees. If you go into the launch ramp areas on the main recreation side try putting in at the north ramp and working into the tree areas from there. There are some steep vert that is adjacent to the trees. My dad said most of the fish being caught are near the trees (typical for this time of year). You can fish it at night. It's a corp of engineers lake for farm water retention so they don't have the same daylight only rules that we have on most of our local lakes. There are many other good places to try, but are hard to get too unless you have a boat. Try topwater and reactions at before the sun comes up. Good luck. BMC
