30. Fish at different depths. If you aren't seeing or enticing fish on or near the surfacce, go deeper. Use a weighted fly or add microshot with a floating line; or switch to a sink-tip or full-sink line. Use the countdown method for systematic depth control. When the fly begins sinking, start counting: one thousand one, one thousand two, etc. Note the number when you start your retrieve. On the next cast, let the fly sink for two or three seconds longer before retrieving. Work your way down to the bottom. If you tangle in weeds on a cast, simply count one or two seconds fewer on the subsequent cast, and you'll be just above the weeds, tangle-free and right in the fish zone.
