Ruedi Dam and the Toilet Bowl
Fryingpan Road leaves Basalt and follows the river 14 miles up to Ruedi Dam. Directly below the dam the outflow spins into a deep round basin, the Toilet Bowl, where the river's biggest rainbows sit in the Mysis shrimp flushed through the dam. Expect company: it is the most watched pool in Colorado. Below it the Flats, the Bend Hole and the bridge pools carry the same fish and the same tiny-fly, fine-tippet game. The top two miles hold the most Mysis and the fattest trout.
The middle river
Public and private water alternate down the canyon and it is well signed, with roughly eight to nine miles of public access in the 14 Gold Medal miles. Pullouts on Fryingpan Road serve the public stretches, and the fish get slightly smaller and less pressured with every mile downstream from the dam. Blue-winged olives in spring and fall, PMDs in summer and the green drakes that start in July and run into October make this the dry fly water.
Seven Castles to Basalt
From the red-rock Seven Castles formation down the last four miles to the Roaring Fork confluence in Basalt, silt on the bottom changes the insect mix and stoneflies and caddis show up alongside the mayflies. This lower river sees less pressure and fishes more like a freestone. Taylor Creek Fly Shop sits on the bank in Basalt and posts the river report.
Rainbow and brown trout
Rainbows dominate the upper river and grow heavy on Mysis, and browns become a bigger share of the catch lower down. Mysis patterns work all year in the top miles, midges carry the winter, and 6X tippet is standard on the flats. Whether a given day produces a giant is up to the fish; the river is famous for them but does not hand them out.
Season and regulations
Releases from Ruedi are set by the Bureau of Reclamation and can jump for downstream water calls. Basalt guides consider about 250 cfs the sweet spot and say the river becomes hard for most anglers to wade at 300 cfs; winter releases drop well under 100 cfs and still fish. This page treats 50 to 250 cfs as in range.
The Fryingpan is open all year. From Ruedi Dam to the Roaring Fork, about 14 miles, it is artificial flies and lures only, all trout except browns must be released immediately, and the brown trout limit is 2 fish of 14 inches or less. You need a Colorado license, and the current CPW fishing regulations are the place to confirm the rest.
