River Map
About Yellow River
The Yellow River in Allamakee County is a medium-sized northeast Iowa Driftless trout stream with strong populations of wild brown trout. Limestone-influenced spring water, classic coulee country topography, and a mix of public-access easements through pasture and woodland. Less crowded than the Upper Iowa mainstem and the famous Bear Creek. Trico spinner falls, Sulphurs, and summer terrestrials anchor the dry-fly action.
Regulations
Iowa fishing license required (~$22 resident annual + ~$14.50 trout stamp; 2026 fee changes — verify current rates on Iowa DNR before publishing). Year-round trout season on most NE Iowa streams. 5-fish daily limit on most streams. Verify Allamakee County special-regulation sections in current Iowa DNR trout regulations.
