About Portneuf River

Portneuf River cuts through Idaho, United States and offers classic river fishing. The local patterns are the universal river patterns: fish the heads of pools at first light, the deep slow water in the middle of the day, and the tail-outs as light fades. Light tackle and a careful drift go a long way at Portneuf River — heavy splashes spook a whole pool.

Fishing Techniques

  • For Rainbow trout

    Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.

  • For Brown trout

    When fishing streams, focus on seams and current breaks, where trout hold to ambush prey.

  • For Mirror carp

    Pre-baiting your chosen swim for several days prior to fishing can significantly increase your chances of success when targeting mirror carp.
