GSL Slip Renters and Marina Users; It is no longer advisable to use the Reef Channel buoys. Storm surge can change the depth over the reef in a short period of time. If you choose to leave the marina area and head out on the lake, it is advised that you now use the Deep Channel buoys. Please keep a close eye on the lake depth as the marina mouth is now quite shallow. At 4196.5 lake level the marina mouth will have a maximum usable depth of 6.0 feet. This means that if you use the ideal approach through the marina you will see some shallow spots at six feet. There are shallower spots if you do not pick the ideal path. Attached is a map and coordinates of the Deep Channel and Reef Channel buoys. But, remember, we do not advise using the Reef Channel for the rest of the 2007 sailing season. We will probably pull 'R-R2' and 'R-R4" buoys sometime in August. Thank you GSL Harbormaster
