Idaho Stillwaters

Springfield Reservoir offers the most convenient still water fishing around. It has been stocked with hatchery catchable rainbows ranging to around 18" and has a population of holdover rainbows running to larger sizes. Midge pupa patterns under an indicator, small black or purple leeches, and fly rod jigs seem to offer the best way to encounter these.
Fly Patterns to use:
Chan’s Balanced Ruby-Eyed Leech Black/Red
Rowley’s Balanced Leech-Black
Rohmer’s BH Simi Seal Leech Canadian Brown
