About Waterloo Creek
Waterloo Creek in Allamakee County is Iowa's most-famous catch-and-release trout stream — artificials only, catch-and-release only in posted sections, and a flagship of decades of Iowa DNR habitat work. Small, cold limestone-spring water with strong populations of wild brown trout and brook trout in headwater refuges. The USGS gauge was downgraded to stage-only in 2023 — no live CFS data is available, so check with regional fly shops before driving.
