From the IJSBA website;
Body Beach is closed on Wednesday or Thursday. Here it is, just a week ahead, and we are still hearing conflicting stories of when Body Beach will be closed to accommodate a boat drag racing event. Most of the reports say it will be closed on Thursday, October 11. It is a royal bummer that it is closing, at all, but there really isn’t anything anyone in the watercraft family can do about it, So, lets just be sure to show how compliant we can all be and what good stewards of the lake that we are and lets just play the cards we are dealt. We are guests in Lake Havasu City and we want to be good guests by following the rules so we can be invited back.
