Frequently asked questions
- What special fishing regulations apply at Teton River (Teton Valley)?
- Teton River (Teton Valley) carries one special-regulation overlay that overrides Idaho's statewide 2026 rules. It reads: "Dominant native Yellowstone-cutthroat fishery: Dec 1 – before Memorial Day trout limit 0 (C&R); Memorial Day weekend – Nov 30 trout limit 6 but no harvest of cutthroat — rainbow harvest is unlimited to suppress non-native rainbow and protect cutthroat genetics." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Teton River (Teton Valley)?
- Yes. Teton River (Teton Valley) is in Idaho, so a valid Idaho fishing license is required just as it is anywhere else in the state, issued by Idaho Department of Fish and Game (IDFG). The special regulations on this page change the bag, size, slot, or gear rules for Teton River; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Idaho rules.
- Do Teton River (Teton Valley)'s special rules replace Idaho's statewide limits?
- Only where they conflict. Idaho's statewide 2026 regulations apply on Teton River by default; the overlays above replace the matching statewide rule for the species or gear they name, while everything not specifically overridden still follows the statewide rule. When a water-body rule and the statewide rule disagree, the water-body rule wins.
