OK, bubba-- Here's what I know. In the spring and fall, the lake whitefish will come out of the depths of Soda and head toward current. You'll find them mostly where the canal dumps into the lake. If you're in a boat, try jigging with a Swedish Pimple or a jigging spoon. Considering the size of the fish, the spoon doesn't have to be too small, but if the water is down, small is better.

From a boat, just vertically jig as if you're ice fishing. you can tip the Pimple with bait-- maggots are probably best, but nightcrawler chunks will work or maybe eveen a single salmon egg-- and the biggest difficulty is finding the schools.

From the bank, you can do well fishing a balanced float and either an ice-fly type of spoon, crappie jig or probably just a hook with bait. Although I haven't tried the last. You can also fish up into the canal to intercept the fish, but be careful, because you might end up hooking nasty trout or walleyes instead of whitey.

If the fish aren't there or aren't biting, I'd head up the canal if on foot, or if in a boat, I'd use my electronics to find schools of fish in the upper end of the lake and jig those. A jigging spoon will catch all you want, but here again you need to be careful as lake whitefish are very strong and will do their best to pull you out of the boat.

Having said all this, I should point out that lake whitefish are all through the system from the Canadian border down, so anywhere you find current in the spring and where there is blocked passage, i.e. a dam, you should find whitefish. For instance, you should be able to find whitefish in the Crab Creek channel in the Potholes, which means that you should be able to catch some at the dam on the south end of Moses.

Looking at this, I see that I haven't mentioned the possibility of fly fishing for them, but I would expect that at the mouth of the canal in Soda you could do well with a sink tip and some kind of fly. I'm thinking a small, bright streamer or flash fly might work or a Zonker or a nymph, or... They'd be a hoot on a fly rod.

Good luck.
