Fishing out of a canoe with no depthfinder, no trolling motor, and no room for a decent net is tough. The current can be your ally or it can be a nightmare. Carry anchors and extra rope for tying off. If the rivers or streams you fish are fast moving, gin clear water like mine, then you'll want to tie off or anchor up at the bends of the river. Always keep your vessel near the point, traversing the shallowest water possible. Personally, I like to beach my boat before a bend and walk the bank to the other side to prevent spooking these little spotted bass.
The reason I fish the bends is simple. The outside edges where the river sharply turns will be substantially deeper than on the inside edge of the bend. Many times, I'm dealing with a subtle drop from 0" of water to around 6ft in depth. The bass pack up in these pockets and wait for baits to come zooming overhead with the current.
This is where walking the bank and heading down river from the bend comes in. Once at the apex of the point, I start casting upriver and reel with the current. Both the small profiled humdinger and the subtle, forgotten grub are perfect lure to mimic a bait fish frantically seeking cover from the current in the depths of these pockets. The hula grub is a smaller profile, subtle little bait which i use to mimic a little crawfish bumping around in the calmer water among the rocks and sticks. I don't bother with using weed guards or weedless lures as all of these are cheap and easy to retrieve. Most of the time, I don't get hung up. If I do, typically I can see what I get hung up on. I'll break the line off, tie on a new lure, fish the spot until I'm done. Then I swim over, dive down, get my bait and go back to the canoe. I don't recommend doing this in the winter for obvious reasons. This is my summer time hobby.
Anytime you're fishing small water, you have GOT to think small. The fish are smaller. The forage is smaller. Little river bass aren't accustomed to hammering blue gill or sun fish. They eat minnows, bugs, and craws. Any large baits may get some reactionary strikes, but you'll do far better with little lures like my little list of canoe favorites. They are cheap lures...save the big bucks for the big fish.
Of course, you can apply these techniques and lures to any body of water and more than likely, you'll be successful. If a guy is burning a spinnerbait, follow up with a white grub with a chartruse dyed tail. Might discover something "new."
