Idaho Angling Services, LLC
Status: published
David Glasscock has been guiding fly anglers on the spring creeks and rivers of south-central Idaho since 1981, building a legendary reputation for technical dry-fly instruction and deep seasonal knowledge. He operates across Silver Creek, the Big Wood, Little Wood, and Big Lost Rivers, and Mackay Reservoir, with mastery of the region's prolific hatches—Golden Stones in early summer, Tricos and Mahogany Duns through August and September, and Blue-Winged Olives into fall. His approach balances instruction with pure fishing opportunity, and he guides year-round, including winter midge hatches for anglers seeking solitude. Glasscock also guides internationally, running trips to New Zealand's South Island spring creeks during the off-season.

"fishingSeasonsNarrative": "My guiding year in south-central Idaho is dictated by the rhythm of the seasons and the incredible hatches that grace our waters. Spring begins with the Big Wood River clearing from runoff, typically by late June, opening up opportunities for dry-fly fishing with Golden Stones and Western Green Drakes. As summer progresses into August and September, the Trico and Mahogany Dun hatches become prime targets on the Big Wood and Silver Creek, with hopper-dropper rigs also effective in the afternoons. Fall is a spectacular time, especially on Silver Creek, where Blue-Winged Olives and late Tricos provide excellent dry-fly action through October. The Big Lost River and Mackay Reservoir offer year-round fishing, with winter midge hatches providing unique opportunities for those seeking solitude on the water.",
"meetingPoint": "home base near Silver Creek",
"providesGear": true,
"gearNotes": "All fly rods, reels, waders, boots, and flies are provided. Clients are welcome to bring their own gear if preferred. Specialty fly patterns matched to seasonal hatches are included on guided days.",
"kidFriendly": null,

"cancellationPolicy": "As long as we receive a cancellation notice 2 weeks prior to the reserved dates, we refund your deposit minus a $25.00 processing fee. If the cancellation is within the 2 week period, we will refund your deposit if we can refill your reserved dates, minus $25.00. If we cannot refill your reserved dates, no refund will be made. We strive to reschedule your reserved dates without any penalty for available dates within the same season.",
"licenseInfo": "Purchase your fishing license in advance from State of Idaho Fish and Game.",
"whatToExpect": "Trips depart from a private home base near Silver Creek, with full-day outings rotating between Silver Creek's technical dry-fly water, the Big Wood's drift-boat runs targeting seasonal hatches, and Mackay Reservoir for stillwater action. Days are dictated by hatch cycles and water conditions—expect dry-fly fishing with Golden Stones in late June, Tricos and hopper-droppers in summer and early fall, and Blue-Winged Olives through October. Streamside lunch is included, and the pace balances instruction with fishing opportunity for all ability levels. Seasons run March through October in Idaho, with winter midge fishing available for dedicated anglers.",
