Frequently asked questions
- What special fishing regulations apply at Big Spring Branch (Grant County)?
- Big Spring Branch (Grant County) carries one special-regulation overlay that overrides Wisconsin's statewide 2026 rules. It reads: "WDNR special-regulation trout stream (Grant County, Driftless Area). Daily bag of 5 trout in total, but all brook trout must be immediately released; brown and rainbow trout have no minimum length. Only artificial lures may be used." Every overlay on this water body is listed in full above.
- Do I need a fishing license to fish Big Spring Branch (Grant County)?
- Yes. Big Spring Branch (Grant County) is in Wisconsin, so a valid Wisconsin fishing license is required just as it is anywhere else in the state, issued by Wisconsin Department of Natural Resources. The special regulations on this page change the bag, size, slot, or gear rules for Big Spring Branch; they do not waive the license requirement. Free-fishing days and youth exemptions follow the statewide Wisconsin rules.
- Do Big Spring Branch (Grant County)'s special rules replace Wisconsin's statewide limits?
- Only where they conflict. Wisconsin's statewide 2026 regulations apply on Big Spring Branch 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.
