Montana Trout Stocking Schedule

Normalized public-agency records with timing guidance and official source links.

Quick answer: Montana trout stocking timing varies by waterbody. Records are added as seasonal field work is completed, with high-country access and ice controlling much of the calendar. Reservoir fry or fingerling releases may take years to affect angling. Our latest normalized snapshot shows 5 reported trout stocking rows during the past 30 days (360 in the trailing 24 months). Data was retrieved September 1, 2026 from Montana FWP FishMT Stocking Records; confirm current conditions with the official report.
