river in Iowa
Yellow River State Forest and its tributaries offer technical dry-fly and nymph fishing in spring-fed sections and strong warmwater fishing lower in the watershed—popular with Driftless fly anglers.
What's working on Yellow River

- 02Trout will be wary and seeking refuge in deeper, cooler pockets and undercut banks. Stealth and precise casts are crucial.
- 03Terrestrial patterns, such as hoppers and beetles, will become increasingly important as summer progresses.
- 04Subsurface nymphs and small streamers remain a reliable option for probing deeper lies where trout and bass may be holding.
- 05Water levels are currently unknown, but historically tight casting conditions are expected in many of the Yellow River's tributaries.
