Idaho Angling Services

The Big Lost is one of the south-central Idaho waters this outfitter names as part of its working beat, and it appears repeatedly in the dated condition reports the company publishes through the season rather than on a trip page of its own. The operation describes the Lost River drainage in connection with Mackay Reservoir, and it is on that reservoir water rather than on the river itself that it runs jet boat trips; across its waters generally it offers wading trips, float tube trips and jet boat trips, sold as single-day or multi-day outings in full-day and three-quarter-day lengths. The trout named across the company’s Idaho rivers are rainbow, brown and cutthroat. No Big Lost specific reach, access point, hatch calendar or price is published anywhere on the domain, so an angler should expect the guide to pick water on the day from conditions, and the running fishing report is the best published guide to what the river is doing at any given point in the season.
