This is the trophy fish of the Brooks River. Anglers come from around the globe to lure these guys into their hands with artificial flies – but only for a few moments - Rainbows are all catch-and-release on the Brooks River. I’ve been watching these fish swim from the banks for the past month but ever since the river opened to fishing I’ve been seeing one or two dead rainbows floating down stream each day. It can be a tremendous thrill to spend twenty minutes or more reeling in one of these animals but it can exhaust the fish, perhaps to the point of death. One purpose of a national park is to allow for recreational uses so long as all is left unimpaired for future generations.
