The lakes I listed are all decent and would be a good option if you were staying @ Canadian Lakes. I mentioned them because I know the fishing in any lake can drop off right after the airboat gets done spraying for weeds. Having said that, I should mention that both Tri-Lakes and Townline Lake get the same treatment.
Tri-Lakes is going to give you numbers of largemouth, with the chance at the somewhat rare smallmouth. If you can find them, some of these brown fish can be bigger than average.
Chippewa Lake is a numbers game and the size is going to be better than Tri-Lakes. Largemouth predominate but there are some smallmouth here as well.
The Martiny Chain is a flooded chain of lakes that is strictly largemouth. A bunch of small lakes connected by channels running through vast fields of lily pads. The place just screams bass, but be warned, it can be the most fickle of the area's lakes. I've been in tournaments where it took five fish to win and the weights went anywhere from 8lbs to 18lbs.
Townline Lake is a real decent lake for largemouth, was a tournament stop for our old Tuesday night trail.
One last area lake I forgot to mention earlier is the backwaters for Hardy Dam. Hardy Pond is long, narrow, has current upstream and tons on submerged wood along its entire shoreline. A tournament held last spring there had a winning weight of almost 20lbs! Great fishing for both largemouth and smallmouth, it just takes a fairly speedy boat to get from one end to the other, is a little dangerous to navigate if you don't know where you are going, and can get crazy busy during the summer.
As you get closer to your trip, shoot me a PM and maybe we can discuss what's going on up here this spring.
