The current will carry the fly into the lake. Flying ant hatches will bring larger fish up along shorelines. Windy days are the best for this along brushy banks. Lakes with lots of shoreline trees and bushes can be fished by roll casting, casting parallel to shoreline or a modified spey cast. The spey type cast can be done by picking up your cast side arm and rolling the rod over your head.
Float tubes work extremely well on lakes that are a shorter hike or day trip.
They allow you a great deal of mobility. I generally inflate my tube and tie it to my pack. You can also carry a small high pressure foot pump. Equipment Two piece rods can be used to pack fish, but for those who do it a lot, multiple piece rods are handy. Rods anywhere from 3 to 8 weight can be used.
