Sand Dune Lagoon

Lake Wollumboola is intermittent. A coastal dune lagoon, enclosed by berm of sand. Its basin a drowned creek-scoured depression. This tiny lake is perched above high tide, vulnerable. Its survival lies at the whim of wind-blown and sea-thrown sand. It's long term fate short-lived as its filling up with sediment, weed, detritus and muck. This little lagoon among the dunes is mecca for migratory birds. The curlew and buff-breasted sandpiper, The long-toed stint, pied oyster catcher and little tern. These vulnerable birds depend on the vulnerable lake. They arrive on-cue from long-hall flights. Alight and feeds in the shallows. Mate, breed and lay eggs in vulnerable places on the open beach and shore. They squat on eggs and fledge their young, and when the time comes, migrate back with young yearling in tow, to whence they came. They book return migratory flights to Lake Wollumboola each year, hoping it survives vulnerable for another year, and hoping its time is not yet up.
