Most insects hatch without so much as a dimple on the water, your presentation must imitate the insects as well. Free floating insects are often trapped in the current and don't create much commotion. A solid casting repertoire allows you to cast in virtually every situation. Be creative when casting in tight spots. 10 -Prevent your shadow from looming over the waters.
Trout know what shadows are natural and what shadows just appear out of no-where.
A sudden shadow alerts trout. 11 - Maintain a level head approach. Don't panic, as you approach a pool have a game plan laid out. If you pooch the pool move onto to the next one with a new game plan. Small streams and creeks require a high degree of delicacy which is next to impossible to learn on a large river.
