The reward for October anglers on the Frying Pan River, north of Aspen, is very low fishing pressure and aggressive browns in the clear, cold tailrace river below Ruedi Dam. Midge and mayfly patterns are the way to go. If September is dry and balmy, you can still catch trout on grasshopper imitations in October. Bring Dave's Hoppers or foam patterns. But the main action is on midge patterns, either Griffith's Gnats or the locally tied Roy's Biot Emerger. The Frying Pan grows some big trout on a diet of mysis shrimp. Fish white shrimp patterns in Toilet Bowl Pool and Bend Pool just below the dam for a mix of rainbow and brown trout to 20 inches. Stripping black or olive Woolly Buggers is a good big-fish tactic all the way downstream to Basalt. Black-and-silver Rapalas are also good big-fish lures.
