Center hill is a little north of where I live, but I've fished it and Percy priest a few times. I've fished tims ford my whole life though and for bass heavily since I was about 9 or 10. Most of the time when it's hot, nighttime is the only time I go to the lake. We just had the first real cold front of the year so the bite will get better from here. Fish are usually shallower during the night than during the day. The fish will come up into coves and Creek arms after the cold snap and I usually don't do as well on the main lake. Try fishing flats, points, and drop offs with black jigs, black spinner baits with a single Colorado slow rolled, black chatterbaits, black 7-10 worms with either ribbon or paddle tails, black buzzbaits, and black jitterbugs. If you want to catch some walleye, stripers, and hybrids as well as bass then try fishing jerkbaits at night. I only use albino white or black(or purple, as long as it's dark). If it's a bait like an f11 floating rapala that doesn't have those colors, I use something shad colored. Try reeling in steadily with floating bombers, rapalas, rogues as well as twitching them. I use rattles with everything at night. Seems to help the fish find it. I catch twice as many on worms or jigs with rattles. As the water cools more and it gets into fall all the shad will come back into the backs of Creek arms and the game fish all follow.
