A floating trout rig is used by casting the bait out into the lake about 15 to 30 feet, letting the sinker descend to the bottom, reeling in the slack line and waiting for the trout to strike. Floating trout rigs are one of the most successful methods of catching trout in lakes. The construction of the rig allows the sinker to rest on the bottom while the bait is attached to a leader that floats off of the bottom.
The construction of a floating trout rig may vary between regions and fishermen but it is generally similar and the intended bait presentation is the same. Typically, a 1/16 to 1/4-ounce egg sinker is threaded onto the fishing line and a snap swivel is tied to the end of the line to block the sinker from sliding off of it. An 18 to 24-inch leader made from two to four-pound test line with a hook on one end is tied to the swivel.
Choosing a bait that floats is the most important part of the trout rig. Many types of synthetic baits are available such as Berkley's Powerbaits and Mike's Glitter or Cheese baits. Fisherman also often use live worms that they inject with air using a syringe.
A strike indicator is an option for those who may have difficulty seeing the line move. It is a floating object that does not interfere with the rig, as a bobber would, but does move noticeably in the water when a trout is taking the bait.
