Electric-only waters in Indiana tend to be managed fishing lakes, and it shows: no wake chop, no fuel sheen, and quiet banks. If you fish from a kayak, a bow- or transom-mount conversion makes you a legal motorboat here — registration rules for motorized craft then apply, so check your paperwork before launch.
Registration still applies once a motor of any kind goes on the boat — electric included in most states, Indiana's rules on the state page here. Bring the card, keep the numbers visible, and you'll clear the only paperwork check that matters on an electric-only lake like Worster Lake.
