Alexander Reservoir

A scenic 1,011-acre fishing reservoir with good boat access next to Soda Springs. Both smallmouth bass and perch fishing have improved in recent years. The reservoir also offers decent catfish and trout fishing with regular stocking.

Species: Yellow Perch, Cutthroat Trout, Smallmouth Bass, Channel Catfish, Rainbow Trout. Difficulty: beginner. Approachable for first-timers and families.

Best timing: Spring and Summer and Fall. Spring fishing keys on warming water and emerging insects. Summer fishes best at first light and late evening; midday is technical. Fall is prime — heavy feeding before winter, fewer crowds.

Regulations: Southeast Region Bag Limits apply. Bass limit 6 (none under 14 inches). Trout limit 6. Always confirm with the current IDFG rule book before fishing.

Southeast context

Southeast Idaho holds the densest concentration of trophy trout water in the state. The Henry's Fork is the marquee fly-fishing river in North America for technical dry-fly fishing; the South Fork of the Snake holds Yellowstone cutthroat-rainbow hybrids; Henrys Lake and Palisades Reservoir produce trophy-sized fish. Driggs, Ashton, Idaho Falls, and Soda Springs are the staging towns.

Family-friendly access — bring kids and beginners.
