Night fishing: No general night-fishing closure in Minnesota. Some designated trout lakes and streams close overnight or have a shortened season, and a few border waters have their own hours — check the current MN DNR regulations for this water.
Boats: Boats and motors are allowed on public waters; some lakes carry no-wake or horsepower limits. AIS law is enforced statewide — drain water, remove plants/mussels, and dry or decontaminate before leaving the access.
Bank & bivvy camping: Camp at state parks, state forest campgrounds, WMAs and DNR rustic campsites; the Boundary Waters needs a BWCA permit. Dispersed shoreline camping outside designated sites is generally not allowed.
Tackle: Statewide bag limits apply (walleye 6, though many marquee and border waters are 4 with a protected slot). Many individual lakes carry special or experimental regulations — check the MN DNR fishing regulations booklet for this water.
