Largemouth and smallmouth bass (a combined total) size limit in Wisconsin

Closes each year Closed to harvest March 8 through May 1 (spring closed season). Catch-and-release fishing for bass stays open year-round even during this window, per Wisconsin's statewide bass catch-and-release allowance.

Harvest is seasonal here, unlike Lake Winnebago where bass may be kept year-round - but anglers may still fish for and release bass on Geneva Lake during the closed window, so the water isn't off-limits, only harvest is.

Closes each year Closed to harvest March 2 through May 1 (catch-and-release only); harvest reopens in early May and runs through March 1

A narrower carve-out exists within about 5 miles of the Door County shoreline and on the Fox, Peshtigo and Oconto rivers up to their first dams, where smallmouth alone get a later, July 1 harvest opener - this site's tracked Green Bay coordinate sits at the city of Green Bay itself, outside that carve-out, so the general Lake Michigan rule above applies.

What we left out on purpose

• Lake Winnebago's own site data (data/reports/lake-winnebago.json) tracks Walleye only as a target species, so its largemouth/smallmouth bass rule (14-inch minimum, 5/day, open all year) is not modelled here even though the DNR page lists it - out of this site's tracked scope for that water. Northern pike was added despite neither water listing it as a tracked target either, specifically because Wisconsin's two-lake, two-species scope otherwise left each species page under the site's three-sibling-link minimum (see SESSION-ANLEITUNG.md, Silo-Regel) - pike is genuinely DNR-regulated at both waters, not invented to pad the count.
• Wisconsin's 'total daily bag limit' (a same-day, cross-water cap, e.g. 5 walleye/sauger/hybrids combined no matter how many lakes are fished) is genuinely different from the possession-limit multiplier concept (KS 3x, ND/UT 2x) used elsewhere in this silo, so no possessionLimit value is set for any Wisconsin region - inventing one would misrepresent how Wisconsin's rule actually works. The statewide 'total daily bag limit' table also lists a separate north-of-Hwy-10 (5) vs. south-of-Hwy-10 (2) default for northern pike; the per-lake numbers here come directly from each lake's own regulation page and are treated as authoritative over that general zone default.
• Muskellunge and flathead catfish carry their own seasons and, on Lake Winnebago, real minimum sizes (muskellunge 50", flathead catfish a 30"-minimum/36-42"-protected-slot combination) - not modelled since neither tracked water lists these as target species on this site; northern pike, by contrast, is modelled (see above) despite the same caveat, purely to satisfy the site's internal-linking minimum.
• Green Bay walleye and bass numbers come from the WDNR's full regulations booklet (2025/2026 edition, cross-checked against the 2026-2027 season-dates guide, which lists no changes to either species on Green Bay) rather than the per-lake lookup tool used for this state's inland waters - that tool's own disclaimer states it only covers inland lakes, and Green Bay is a boundary/outlying water.
