Frequently asked questions
- What special fishing regulations apply at Topock Marsh?
- Topock Marsh carries one special-regulation overlay that overrides Arizona's statewide 2026 rules. It reads: "Lower Colorado River backwater in the Havasu National Wildlife Refuge above Lake Havasu — largemouth + smallmouth bass 6 / day combined, 13-in minimum; crappie 25 / day combined with sunfish; channel + flathead catfish 10 / day combined; fishable on the Arizona license (Colorado River boundary-water privilege bundled in)." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Topock Marsh?
- Yes. Topock Marsh is in Arizona, so a valid Arizona fishing license is required just as it is anywhere else in the state, issued by Arizona Game and Fish Department (AZGFD). The special regulations on this page change the bag, size, slot, or gear rules for Topock Marsh; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Arizona rules.
- Do Topock Marsh's special rules replace Arizona's statewide limits?
- Only where they conflict. Arizona's statewide 2026 regulations apply on Topock Marsh 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.
