Frequently asked questions
- What special fishing regulations apply at Mousam Lake (Acton & Shapleigh, York County)?
- Mousam Lake (Acton & Shapleigh, York County) carries one special-regulation overlay that overrides Maine's statewide 2026 rules. It reads: "South Zone. Smelt taking restricted to hook-and-line, direct tributaries closed. No minimum length and no bag limit on togue (lake trout) under 23 in; togue over 23 in 1 / day. October 1 – December 31 artificial-lures-only with all trout, salmon and togue released alive. Southern-Maine salmon and togue lake — the modern Maine state-record brook trout (9 lb 2 oz, 2010) came from Mousam Lake. (MDIFW 2026 Special Fishing Laws.)." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Mousam Lake (Acton & Shapleigh, York County)?
- Yes. Mousam Lake (Acton & Shapleigh, York County) is in Maine, so a valid Maine fishing license is required just as it is anywhere else in the state, issued by Maine Department of Inland Fisheries & Wildlife (MDIFW) — freshwater; Maine Department of Marine Resources (DMR) — saltwater. The special regulations on this page change the bag, size, slot, or gear rules for Mousam Lake; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Maine rules.
- Do Mousam Lake (Acton & Shapleigh, York County)'s special rules replace Maine's statewide limits?
- Only where they conflict. Maine's statewide 2026 regulations apply on Mousam Lake 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.
