Flows have been on the rise on the Thompson. On the freestone sections, large stoneflies, caddis, mayflies and various attractor patterns have been working well.

The tailwater is on a similar program, sizing down baetis and stonelfy patterns as well as mixing in scud, worm and caddis patterns have been successful recently.

Streamers can also be effective on the Thompson with smaller minnow and crawfish patterns.
