The Copper Basin area is home to most of the Lost River tributaries and the beginning of the Lost River proper. This remote setting is graced with plenty of fish and miles upon miles of fishable water. Primarily a dry fly fishery, the Copper Basin area is home to our unique “Grand Slam” of fishing, as each year a few anglers are able to catch the entire gamut of fish in this area in a single day. Five species comprise the Copper Basin Slam, including Rainbow, Brook, two types of Cutthroat and the Mountain Whitefish. It is a true wilderness experience to travel into this area and anglers are rewarded with spectacular views, loads of wildlife and exceptional fishing opportunities.
