Frequently asked questions
- What special fishing regulations apply at Lake Lillinonah?
- Lake Lillinonah carries 5 special-regulation overlays that override Connecticut's statewide 2026 rules, covering Largemouth bass, Smallmouth bass, Northern pike, and Channel catfish. One of them reads: "1,540-acre Housatonic River impoundment downstream of Shepaug Dam; 12 in min largemouth + smallmouth, 6 / day combined; trophy smallmouth on rocky shorelines; walleye 18 in min, 2 / day; northern pike / muskellunge 1 / day (pike OR muskie, not both) 38 in min; channel catfish 6 / day aggregate + carp." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Lake Lillinonah?
- Yes. Lake Lillinonah is in Connecticut, so a valid Connecticut fishing license is required just as it is anywhere else in the state, issued by Connecticut Department of Energy & Environmental Protection (DEEP) — Inland Fisheries + Marine Fisheries Divisions. The special regulations on this page change the bag, size, slot, or gear rules for Lake Lillinonah; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Connecticut rules.
- Do Lake Lillinonah's special rules replace Connecticut's statewide limits?
- Only where they conflict. Connecticut's statewide 2026 regulations apply on Lake Lillinonah 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 Lake Lillinonah?
- Largemouth bass, Smallmouth bass, Northern pike, and Channel catfish have a water-body-specific rule on Lake Lillinonah, each linking to its full Connecticut regulations above. Species not listed here follow the statewide Connecticut limits.
