(Rick Egan | Tribune file photo) Division of Wildlife Resources biologist Mike Slater releases native Bonneville cutthroat trout into upper Mill Creek in 2014 after removing all trout from the stream above Salt Lake City. In partnership with the Dixie National Forest, Utah wildlife officials are pursuing a similar project on the Paunsaugunt Plateau when they apply a piscicide to Blubber and Upper Kanab creeks, which will be closed for several days.
