Caught a 19 lb cat out of Sprague lake before they poisoned it trolling bait (probably closer to drifting). Mainline down to about a 1 ounce egg sinker attached to swivel then about 18 inch leader with a small bobber threaded on the line (the ones with the plastic insert to stop it from sliding on the line) and a wide gap, almost circle hook about 8 inches down from the bobber. This keeps the bait off the bottom. I used thread fin shad that I had brought over frozen from North Carolina. If there is a gentle wind, position yourself upwind and drift bouncing the sinker on the bottom. If there is not much wind, you can use slow speed on a trolling motor. If there is too much wind, you may use the trolling motor to slow you down, or a water anchor.
