Small Streams, August 29th, 2023

Mahogany Dun

Good mayfly activity will begin on many streams as we begin the fall emergence peak. Gone are such as brown, gray and green drakes, flavs, and march browns. Only a few smaller PMDs are around on some waters. Tricos are diminishing, but speckled duns will remain in good numbers for weeks especially on still waters..The fall BWO hatch will begin any day now and carry on until winter sets in with such as tiny BWOs included. Pink alberts, also know as snowflake duns, will remain for a while. Mahogany dun hatches will be important and widespread. The Hecuba may fly hatch, more scattered and less consistent will appear on relatively soft bottomed streams. Mistakenly called green drake because of its size, it is famed for consistency on such as Slough Creek, but is less abundant on most Fall River Basin streams having a similar substrate.

A single track bypass road has been opened around the damaged section of the road to Bear Creek. The bypass road is suitable only for single vehicles, but not for those with a trailer. More information on the bypass can be obtained from the Caribou-Targhee Palisades District Ranger Station. Reconstruction of the main road will not be completed this year.
