I think the huge volume of water in the clot is due to the wettest January to May in 150 years, an owner on our phase told me that while he was in GA for January it rained every day for three weeks . Think the clot water is fresh and not salt or even brackish given the reeds that grow around the margins. I took my binoculars to the clot in June and it was wonderful, saw a marsh harrier, first one I've seen there. I suspect that more water run off from the estate is being diverted to the clot which might account for the bigger lakes at the moment.
