All the small planted trout in Rock Lake seem to have migrated to the north end, so if you are targeting larger bows and browns, stay about a mile south of the inlet creek along the eastern shoreline. Trollers dragging an assortment of lures and flies are finding fish running 12-16 inches. Launching a boat at Rock particularly one over 14 feet" can be an ordeal. Be careful not to get the trailer tires over the drop-off on the gravel ramp. At best, launching at Rock is a two-man job, and one of them should be wearing hip boots.
