Island conditions

Real map. Real plume. The whole island.

The shaded overlay is the modeled sediment plume from every archipelago river with usable hydrology running simultaneously as one combined source, not picked one at a time. Beaches below are ranked worst-visibility-first, so the places worth checking surface immediately instead of getting lost in a map of "likely clear" dots.

Screening-class estimates only — never calibrated diver visibility, never a safety determination. Full methodology at the field lab.
