Lake Raymond
Three acres south of the Upsidedown Creek Trail, with nothing published about it anywhere. We saw mountain goats here.
Diamond Lake (Boulder)
On the Upsidedown Creek Trail at 9,609 feet, half a mile east of Horseshoe. Nothing published about it anywhere.
Horseshoe Lake (Upsidedown Creek)
A wide shallow spot in the creek and the first lake on the Upsidedown Trail. Self-sustaining cutthroat, running smaller than they did ten years ago.
Chickadee Lake
Eight feet deep and holding self-sustaining cutthroat to sixteen inches off a spring-fed spawning inlet. Excellent camping just below the lake.
Mirror Lake (Boulder)
Eighty feet deep and the best camping on the Lake Plateau. FWP has been stocking cutthroat at high density since 2011 to swamp out the rainbows.
Squeeze Lake
Seven acres and uniformly deep, holding stocked cutthroat that have averaged 12.5 inches across two surveys seven years apart.
Rainbow Lake (Boulder)
Six numbered lakes on one page, running from 9,407 to 9,765 feet. Self-sustaining rainbows and thirty-nine thousand cutthroat stocked in three years.
Pipit Lake
Seven acres on excellent trail across the plateau, with fat rainbows that nobody can account for. Nice camping and plenty of firewood.
Owl Lake
Fourteen acres on trail across the plateau, holding rainbows to nearly twenty inches. FWP fished it in 2025 and landed one.
Diaphanous Lake
Empty for forty years, then stocked with arctic grayling in 2022 and holding them by 2025. Excellent camping, and on trail from every direction.
Jay Lake
Twenty-four acres at 9,794 feet with self-sustaining cutthroat to seventeen inches. Somebody put five thousand largemouth bass in it in 1988.
Chalice Lake
Eight acres at 9,625 feet, two miles northwest of Lake Surrender and off trail. The prettiest lake we saw in nine days on the plateau.
Lake Vengence
Just over an acre at 9,956 feet, at the far corner of the basin above Lake Surrender alongside Hermit. Nothing published about it anywhere.
Hermit Lake (Clarks Fork, MT)
Three acres at 10,034 feet, the highest and furthest corner of the basin above Lake Surrender. Nothing published about it anywhere.
Asteroid Lake
Three acres and forty feet deep, stocked with goldens meant to seed the water below it. Good camping, and the only decent firewood up here.
Comet Lake
Nine acres at 9,347 feet, half a mile southeast of Needle in the upper basin above Lake Surrender. Nothing published about it anywhere.
Needle Lake
Two acres a third of a mile below Dryad, and the crossroads for the whole upper basin. Nothing published about it anywhere.
Dryad Lake
Five acres and forty-five feet deep, holding golden trout to nearly nineteen inches. FWP netted them and could not catch one on a rod.
Bill Lake
The lowest lake on the Flood Creek side, with good numbers of hybrids. The short way in is four trailless miles FWP calls torture.
Cimmerian Lake
Nineteen acres on Flood Creek with three self-sustaining populations and fish to seventeen inches. FWP says they fight hard.
