While out West Trout fishing, there were times that there were either too many trees or bushes to use my fly rod from the bank. In such cases I would use either my ultra-lite/light rod and reel to cast a fly out. Since the fly or Salmon egg was too light for any distance I used a bobber as pictured below. They come in all sizes. The center will slide out and you can dunk it in the water and add some for weight. Using a small rubber bobber stopper and split shot enables the bobber to slide down the line thus not having 4'-6' hanging and trying to cast.
