This is a great time of year to fish the Park. While the valleys surrounding Yellowstone can get quite hot, the Park has cooler temps at it's higher elevation. The northest corner is fishing great with the cool weather that came through this week. Early morning is time to fish small PMD's. When the air finally starts to warm the hopper fishing will begin to pick up steam. It is still good to have a PMD emerger dropped under your hopper pattern. The Yellowstone River would be my next choice if I wasn't going into the Lamar Valley area. The PMD's are out but are tiny now. Stimulators, hoppers and ants are your mid-day patterns. The Park also has a lot crickets so remember to try a small black hopper. If you don't have any patterns that are black bring a sharpie and color one of your tan hoppers black. The west side of the Park has some fishable water temps again on the Gibbon and Madison. Early or late in the day are the best times to be on the rivers in this area.
