Genetically Unique Cutthroat Trout Rescued From 2016 Wildfire are Found to be Reproducing in SE Region Streams

Colorado Parks and Wildlife (CPW) biologists have observed promising signs that their efforts to save a genetically unique cutthroat trout from Hayden Creek, threatened by the 2016 Hayden Pass Fire, are paying off. Recent surveys in southeastern Colorado streams have found evidence of these trout surviving multiple years and reproducing naturally, marking a significant milestone. Since the rescue operation, CPW has reintroduced over 8,000 of these fish into Newlin Creek and 135,000 into 18 streams and lakes across the Arkansas River drainage, establishing multiple age classes and indicating a positive trajectory for this unique trout species.
