Even fishing a lake while the ice is receding may require a variety of fly lines, so make sure your kit bag has the essential lines from the very first trip of the season. Floating, hover, intermediate and faster sinking lines in type 3, 5 and 7 will cover any fishing tactic required in your trout lakes. Trout are not normally very leader shy in the early spring as the intense insect hatches have not begun. Carry spools of good quality 3X, 4X and 5X monofilament or fluorocarbon tippet.
