Yellowstone Park 8-25-12

Thundershowers are predicted for this weekend.  If they happen, look for fishing on most streams to pick up.  Only “fly in the ointment” would be a shower with a direct hit on stream side formations with a tendency to erode and slough into the stream. This happens on the Lamar and Snake rivers frequently during big showers.  Go with tricos for early morning action, and switch to terrestrial patterns around mid day for most streams.
