Everything is illegal in BML lol. The Beech Mtn police may or may not give you a hassle. I moved away several months ago. We did ice fish it from time to time. Getting on by the clubhouse can be tough. Bubblers and a creek coming in there can make it impossible to get on around there. If you come on from lakefront property you should be ok. I lived close to the spillway. We would park by the timeshare and access from there. Weekends are likely to be less of a problem. During the week when the offices are open is when I have heard of people getting grief. We usually stayed around the island. Most people seem to go across from the beach off the point. That is the deepest water out there.
