Trout Unlimited, Inc. will install a fish ladder on a diversion structure within the mainstem of Greybull River, located 25 miles west of Meeteetse, Wyoming. The existing structure diverts water for agricultural uses and is a complete barrier for all native fish in the Greybull River, including Yellowstone cutthroat trout. The structure will be replaced by the Greybull Valley Irrigation District during the summer of 2011. Trout Unlimited, Inc. has received permission to install a fish ladder on the new diversion structure for the purpose of providing fish passage and accessibility to over 60 miles of habitat, including historical spawning and rearing tributaries for Yellowstone cutthroat trout. Project partners include the U.S. Fish and Wildlife Service, Wyoming Game and Fish Department, Greybull Valley Irrigation District, Wyoming Wildlife and Natural Resource Trust, and the ranch landowners.
