Frequently asked questions
- What special fishing regulations apply at Mt. Sterling Lake (Brown County)?
- Mt. Sterling Lake (Brown County) carries one special-regulation overlay that overrides Illinois' statewide 2026 rules. It reads: "Mt. Sterling city lake, west-central IL; largemouth + smallmouth 12–15 in protected slot; channel catfish 6 / day." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Mt. Sterling Lake (Brown County)?
- Yes. Mt. Sterling Lake (Brown County) is in Illinois, so a valid Illinois fishing license is required just as it is anywhere else in the state, issued by Illinois Department of Natural Resources. The special regulations on this page change the bag, size, slot, or gear rules for Mt. Sterling Lake; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Illinois rules.
- Do Mt. Sterling Lake (Brown County)'s special rules replace Illinois' statewide limits?
- Only where they conflict. Illinois' statewide 2026 regulations apply on Mt. Sterling 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.
