There are a lot of bays here and in the spring, lots of fish will move into these areas as water temperatures warm up. The newer green weeds with some warmer water will attract a variety of fish. This is a big lake and the wind can move the warmer water around quite a bit, so make sure to find the warmer water because you will usually find a lot more active fish.

In the summer, the fishing can be a lot tougher here on many anglers because the lake is so big and the fish have a lot of room to spread out. Learn to fish the deeper weed edges and offshore structure to find some of the bigger schools of fish. The quality fish will usually be out deeper on the main lake as well. You can still find plenty of fish shallower, in the bays and along the mainland shorelines, however, good numbers of fish move offshore and if you learn how to find them, you should have more success in the summer.

| Month | Avg. Temps °F (Hi/Lo) |
| September | 68° / 45° |
| October | 53° / 33° |
| November | 36° / 19° |
The fall is transition time and there is a lot of water here for fish to spread out. Some fish move shallow, while some stay deep. You may want to bounce around until you find a pattern. It may be different on any given day in the fall. For the shallow water anglers, you can fish a lot of that 4 to 10 foot water again and catch fish like in the spring. Just don’t expect as many fish as the spring. If you want to stay deep, that can pay off also. As water temperatures cool down and the fall comes to an end, the better bite will almost always be deeper for just about every species of fish in the lake.

The pike fishing can be good in the winter also if you can find them.
