The message below originally appeared on the AGLCA forum, as part of a discussion as to whether one could anchor on Lake Okeechobee itself. The strong consensus was that this is a bad idea.
Below, Captain Jim gives us some good advice on where you might tie to a set of dolphins, or possibly even anchor east of the Lake Okeechobee and the Port Mayacca lock. Notice also his endorsement of nearby Indiantown Marina. We have always found this to be a good place to coil one’s lines.

If you go through the lock, eastbound, there is a set of dolphins in the canal there. You can tie between the dolphins and stay the night. People do also anchor there, in the pool area immediately east of the dolphins. Room for maybe two boats. Mind the red channel marker there’ it marks a boulder! Only once in a dozen times through there have we seen commercial boats use the dolphins, but it is possible to see a small tug there, maybe a tug and barge.
About 8 – 10 miles east of Port Mayaca is a marina called “Indiantown.” It’s popular, and I suggest you make reservations ahead, but it’s a nice stop.
Hope this is useful
Jim
