The water flows, has quite a lot of fish, turtles and while rarer...rays come in and hunt so it's not stagnant. I do know an owner on a neighboring community that jumps off of their dock for exercise swimming - no idea if this is considered acceptable for the lagoon but as far as Waterlands goes I do believe we at least have no diving signs. Personally I would just go to the end of the road and swim off of Windsock anyway. Maybe it is tempting from a 'hang around the house' standpoint but for me the ocean is too hard to resist.
