Mongolia’s fishing year runs roughly from ice-out in spring to freeze-up in late autumn, interrupted in the middle by summer run-off that can colour the rivers for several weeks. Taimen, lenok and grayling all fish differently depending on where you are in that cycle, and the short autumn window before freeze-up is generally the most sought-after time for taimen specifically.
Exact opening and closing dates are set annually and confirmed with your outfitter closer to travel — we would rather tell you honestly that a date is not yet fixed than give you one that turns out to be wrong.
| Spring (ice-out) | Rivers open, water still cold; confirmed at enquiry |
|---|---|
| Early summer | Water can be affected by run-off; variable by year |
| Late summer | Generally stable water, good all-round fishing |
| Autumn | Shortest window, most sought-after for taimen; confirmed at enquiry |
| Freeze-up | Season closes; date set annually |
Highlights
Two windows stand out — the weeks right after ice-out and the short autumn run before freeze-up, when taimen fishing is at its best.
Good to Know
Summer run-off can colour the water for several weeks and isn’t the strongest fishing window — plan around it rather than into it.
