While it is obvious that the laguna would be blocked by the build up of sand over time and break out periodically depending on rain volumes, there is another element to consider. Has the lirio ( water hyacinth ) increased over the years like in Melaque? And has the nitrate level in the laguna increased from adjacent human activity? Are there anoxic events when there are strata of water with no dissolved oxygen? If these conditions exist the laguna is on its way to becoming a bigger problem.
