Frequently asked questions
- What special fishing regulations apply at Big Diamond Pond (Stewartstown, Coos County)?
- Big Diamond Pond (Stewartstown, Coos County) carries one special-regulation overlay that overrides New Hampshire's statewide 2026 rules. It reads: "NHFG lake-trout / salmon water — no minimum length for trout; lake trout 15 in minimum, 2 / day; combined salmon + trout 4 / day of which no more than 2 may be salmon (vs the statewide 5-trout default); a North Country togue + landlocked-salmon pond." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Big Diamond Pond (Stewartstown, Coos County)?
- Yes. Big Diamond Pond (Stewartstown, Coos County) is in New Hampshire, so a valid New Hampshire fishing license is required just as it is anywhere else in the state, issued by New Hampshire Fish & Game Department (NHF&G) — Inland Fisheries Division + Marine Fisheries Division. The special regulations on this page change the bag, size, slot, or gear rules for Big Diamond Pond; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide New Hampshire rules.
- Do Big Diamond Pond (Stewartstown, Coos County)'s special rules replace New Hampshire's statewide limits?
- Only where they conflict. New Hampshire's statewide 2026 regulations apply on Big Diamond Pond 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.
