Hatch Status

Still find a few Tricos and an array of caddis

Conditions

The Big Wood is running low and clear through mid-August, a situation that rewards stealth and precision. Larger trout will spook easily in thin water, so work between access points to find less pressured fish. Morning sessions should focus on Tricos and caddis, with small hoppers and ants taking fish in the afternoon. Micro nymphs on fine tippets will reward anglers targeting selective feeders.

Techniques

  • Small hoppers and ants are a good bet in the afternoon, micro nymphs also working well
  • Success depends on employing stealth; larger fish are very spooky and will only give one chance to make undetected presentation
