Before you go
Rules change, and some lakes close for the season or have their own permits. We link each lake to the agency page that states its motor rule, and show the month we checked it (most recently October 2026). Confirm the current rules with the lake's manager before you head out. Your state's boat registration and safety-equipment rules still apply on electric-only lakes.
