Situated on the Derwent estuary system, at Elwick Bay, GASP responds to the lapping tides. The tidal waters produce an ever changing environment of mud flats and inundations. Bird and marine life come and go. The little blue boat ‘Robin’s Boat’ moored, just beyond shore, bobs on the surface. Often described as windy the prevailing nor-westerly can disappear completely leaving the bay appearing as a protected lake.
