Dry-Fly Line Mending Principles
In general, there are two main principles to follow while mending your line while fishing a dry fly:

  • The angler should use upstream mends to compensate for faster flowing surface current between the angler and the end of the fly line.
  • The angler should use downstream mends to compensate for slower flowing surface current between the angler and the end of the fly line

Wet-Fly Line Mending Principles
In general there are two all-purpose principles to follow in wet fly line mending:

  • The angler should use upstream or downstream mends in order to achieve an initial drag-free drift for the fly. This free drift will in turn allow the fly to sink down in the water column.
  • When the desired depth is reached, the angler will again mend the line, but this time across the faster flowing current. Fast moving water will cause the belly of the line to be pushed at a faster rate, resulting in an upward swing of fly as it passes its respective target.  (Bass Pro Shop…yes, yes, good enough for April…good enough for you).
