A big visitor weekend is coming up with Labor Day, so expect company, even in some back country locations. Whatever streams you choose, terrestrial patterns are a must. This is really true if flying ant swarms are where you fish. Be sure to have some cinnamon ant patterns in size 14. Look for tricos to dominate AM fishing along some parts of Fall River Basin streams and the Madison River drainage. Slough Creek will feature a green drake emergence. We need to cool off more for the Firehole River to shape up to fall fishing form. Run-up browns and ‘bows from Hebgen Lake are beginning to show in the Madison River. Gulpers are still active on Beula Lake, but expect crowds on this last big weekend of the summer season. Small streams such as Obsidian, Cascade, and Polecat creeks host eager trout for light weight equipment fans. So there will something for whatever your fly fishing preference may be.
