GSL Slip Renters and Marina Users. There is a large swim event this Saturday morning. The event will force us to close access to and from the lake Saturday morning for a brief period of time for the safety of the swimmers. The marina mouth will be closed from 8:45am to about 9:15am. This will be a short half-hour closure. Please do not try to access the lake or return back to the marina during this brief period of time. The marina mouth will be open the rest of the day. Thank you, for your understanding. Dave
