Fishing Conditions

June 20, 2018

 The Park experienced all four seasons this weekend but the fish didn't care. All the places with good conditions are on the west side of the Park still. The Firehole and the Gibbon have the best conditions. They both have some fish feeding on the surface with Caddis. More are feeding on top as you go later into the day. With the warmer temps on the Firehole there are PMD's in the middle of the day. The upper Gallatin has dropped over a foot and is back to a good green. If you go very high, above Fawn Creek, the river is almost clear. Water temps are still low which is not allowing for hatches yet. The fish are still hunkered down and are eating nymphs. Worms and big stonefly patterns are getting good attention. If you are thinking streamer fishing, start with either a dark pattern or a flashy one that is easy to spot.
