The Nature Conservancy will prevent entrainment of fish into an irrigation ditch and reduce impacts to native fish recruitment and reintroductions of Yellowstone cutthroat trout by installing a fish screen and bypass system in Bull Lake Creek.  The Nature Conservancy in Wyoming owns and operates the Winchester Ranch approximately 10 miles east of Crowheart, Wyoming on the Wind River Indian Reservation in central Fremont County. Passing through the ranch is a 1.4-mile portion of Bull Lake Creek and over three miles of the Wind River, supporting a significant trout fishery, native trout recruitment and providing important riparian habitat to numerous fish and wildlife species. The Nature Conservancy, together with the United States Fish and Wildlife Service, the Natural Resources Conservation Service, and Trout Unlimited, initiated fisheries enhancement projects on Bull Lake Creek in 2004. Phases 1 and 2 of the enhancement projects have been completed. In Phase 3, the fish screen and bypass system will prevent the entrainment of thousands of fish per year into the irrigation ditch, reduce impacts to the wild rainbow and brown trout fishery, native fish recruitment and reintroductions of Yellowstone Cutthroat occurring in the Bull Lake Creek system.
