Frequently asked questions
- What special fishing regulations apply at Keyhole Reservoir?
- Keyhole Reservoir carries 3 special-regulation overlays that override Wyoming's statewide 2026 rules, covering Walleye and Yellow perch. One of them reads: "Walleye 6 / day with 15 in min Quality Management; smallmouth + largemouth bass 6 / day combined + 12 in min; northern pike 6 / day no min; channel catfish 6 / day no min — WY state-record smallmouth bass 7 lb 1 oz Keyhole 2003." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Keyhole Reservoir?
- Yes. Keyhole Reservoir is in Wyoming, so a valid Wyoming fishing license is required just as it is anywhere else in the state, issued by Wyoming Game and Fish Department (WGFD). The special regulations on this page change the bag, size, slot, or gear rules for Keyhole Reservoir; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Wyoming rules.
- Do Keyhole Reservoir's special rules replace Wyoming's statewide limits?
- Only where they conflict. Wyoming's statewide 2026 regulations apply on Keyhole Reservoir by default; the overlays above replace the matching statewide rules 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.
- Which species have special rules on Keyhole Reservoir?
- Walleye and Yellow perch have a water-body-specific rule on Keyhole Reservoir, each linking to its full Wyoming regulations above. Species not listed here follow the statewide Wyoming limits.
