The shape of Mason Lake decides where the fish sit.

• Tackle & Baits

  No public source sets out the position on this bank. This is a natural basin, not a dammed one. Nothing is listed nearby for parking or launching a boat. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Some banks are open only from a marked point. Where parking is tight, arriving early solves most problems. Should this one be busy, Frank Lake is 0.9 km off. Rules at Mason Lake are worth checking on the day.
