One of the most common questions I get regarding nymphing is how to know if you’re fishing your nymphs in the strike zone? Since we can’t always see at what level fish are feeding below the surface, we have to work with is our knowledge and powers of observation to formulate an educated guess.
There’s a well-heeled saying which proclaims that you’re not nymphing correctly if you aren’t constantly snagging bottom. As a result, many anglers believe they need to bounce their nymphs along the stream bottom at all times. This is most certainly an overstatement.
