The Tribasin Divide

The Tribasin area is a renowned destination for anglers seeking to complete the Wyoming Game and Fish Department’s (WGFD) Wyoming Cutt-Slam, because of the three cutthroat trout species found in a relatively small area. Trout Unlimited (TU) and the Bridger-Teton National Forest (BTNF) partnered in Phase 2 of the Tribasin Fish Passage and Watershed Restoration Project which began during the summer of 2020. The project is a large-scale, multi-phased project initiated in 2018 to improve ecosystem function and reconnect stream habitat for cutthroat trout and other native fish species on BTNF lands. The construction implementation includes replacing an undersized culvert on the Greys River, near the confluence of Shale Creek, with a newly constructed bridge, as well as replacing 3 undersized culverts on Mink Creek, Clear Creek, and the West Fork Greys River.
