Flowing west from the Pumphouse Recreation Area, this section of the Colorado River carves its way through dramatic canyon walls and sweeping bends that define the upper reaches of Little Gore Canyon. It’s one of the most iconic floats and fisheries in Colorado—a mix of wild scenery, healthy trout populations, and cold, clear flows that stay productive throughout much of the year. The river here offers a perfect combination of deep runs, riffles, and slower eddies that invite a range of approaches, from nymphing and streamer work to classic dry-dropper fishing along the banks. Anglers can expect strong brown trout numbers with the occasional rainbow in the mix, and steady hatches of midges, mayflies, caddis, and stoneflies that keep the fish active from spring through late fall. Access begins at Pumphouse Recreation Area, managed by the Bureau of Land Management, and continues downstream toward Radium. The stretch through Little Gore Canyon is especially scenic, with towering rock faces, hidden side channels, and a true sense of remote wilderness that belies its accessibility. It’s equally rewarding whether you’re wading the edges or floating through in a drift boat or raft.
