We were told that some volunteers are helping to remove the mangroves. Basically, the walls of the fishpond is intact except that there is minor damage close to the eastern most makaha. There are three sluice gates in this pond. The east makaha is close to the mangrove area but it still works well. The other two makahas also are in good condition.
Water can easily go in and out the fishpond during the tidal cycle.
Sedimentation does not appear to be a major problem. According to our observations, the water at the sluice gates is very clean during both the low and high tides. Inside the pond, there is 1-2 feet deep mud. But it is observed that the sand outside the pond is very different from that inside the pond. Therefore, it seems that the mud inside the pond comes from the land or some other source, not from the ocean in recent times.
