Frequently asked questions
- What special fishing regulations apply at Nuʻuanu Reservoir No. 4?
- Nuʻuanu Reservoir No. 4 carries 2 special-regulation overlays that override Hawaii's statewide 2026 rules, covering Largemouth bass. One of them reads: "Oʻahu secondary freshwater venue; largemouth + smallmouth + bluegill + catfish + tilapia; DAR-managed; Freshwater Game Fishing Licence required ages 9+." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Nuʻuanu Reservoir No. 4?
- Yes. Nuʻuanu Reservoir No. 4 is in Hawaii, so a valid Hawaii fishing license is required just as it is anywhere else in the state, issued by Hawaiʻi Department of Land and Natural Resources (DLNR) — Division of Aquatic Resources (DAR). The special regulations on this page change the bag, size, slot, or gear rules for Nuʻuanu Reservoir No. 4; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Hawaii rules.
- Do Nuʻuanu Reservoir No. 4's special rules replace Hawaii's statewide limits?
- Only where they conflict. Hawaii's statewide 2026 regulations apply on Nuʻuanu Reservoir No. 4 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 Nuʻuanu Reservoir No. 4?
- Largemouth bass has a water-body-specific rule on Nuʻuanu Reservoir No. 4, each linking to its full Hawaii regulations above. Species not listed here follow the statewide Hawaii limits.
