Frequently asked questions
- What special fishing regulations apply at Lake Washington + Lake Sammamish?
- Lake Washington + Lake Sammamish carries one special-regulation overlay that overrides Washington's statewide 2026 rules, covering Largemouth bass. It reads: "Western-WA urban lowland lakes — statewide lake slot rule 5 / day, retain only bass under 12 in plus 1 over 17 in." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Lake Washington + Lake Sammamish?
- Yes. Lake Washington + Lake Sammamish is in Washington, so a valid Washington fishing license is required just as it is anywhere else in the state, issued by Washington Department of Fish and Wildlife (WDFW). The special regulations on this page change the bag, size, slot, or gear rules for Seattle urban lakes; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Washington rules.
- Do Lake Washington + Lake Sammamish's special rules replace Washington's statewide limits?
- Only where they conflict. Washington's statewide 2026 regulations apply on Seattle urban lakes 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.
- Which species have special rules on Seattle urban lakes?
- Largemouth bass has a water-body-specific rule on Lake Washington + Lake Sammamish, each linking to its full Washington regulations above. Species not listed here follow the statewide Washington limits.
