In a Sept. 5, 2017 photo, fish biologist Ben Schleicher of the U.S. Fish and Wildlife Service holds the second Colorado pikeminnow to make passage over the Grand Valley Water User's Dam in 2017. The fish was first encountered and tagged on April 30, 1993, in the Colorado River near Westwater Ranger Station in Utah. It has been since encountered in the Colorado River near Palisade in 1998 and 2009; in the Colorado River near Fruita in 2013; and detected on the historic Price Stubb Dam just upstream of Palisade in 2017. The approximate age of this fish is at least 28 years.
