About Rathbun Lake

Rathbun Lake sits in Iowa, United States and offers the kind of structure-driven lake fishing that suits both bank anglers and those working from a small boat or float tube. Fish on a stillwater like this don't move much during the heat of the day — finding shade, cooler thermoclines, or current from inflowing streams is the local trick. Most successful trips to Rathbun Lake come down to reading the water before tying on a lure.

Fishing Techniques

  • For Hybrid striped bass

    Look for structure or drop-offs where hybrids ambush prey; Vary your retrieve until you find what they want.

  • For Walleye

    Focus your efforts around dawn and dusk, as walleye are typically more active during these low-light periods; use a slow, deliberate retrieve, as walleye often prefer a subtle presentation.

  • For Channel catfish

    Fish near structure like submerged trees or rocks, as channel catfish often use these areas for ambush points and shelter.
