When you are looking for big browns and rainbows never underestimate small and moving water, where there is enough water speed, shade and food.
The secret is to look for shades and movement and try to find out where they are holding.
Analyze the way you'll approach you target (trout). Try to keep a safe distance from the bank, so no motion or noise will be detected by trout.
If there are more than one trout in the same run, start from the lowest and work your way upstream! Hope you enjoy this video!
