The Eems-Dollard is a coastal estuary located on the border between the Netherlands and Germany, where the River Ems meets the Wadden Sea. It is the only estuary of the Wadden Sea and one of only two remaining estuaries in the Netherlands. The mixing of fresh and salt water creates unique environmental conditions. The area is characterized by significant turbidity due to permanently suspended silt, with recent measurements showing sediment concentrations of up to 160 milligrams per litre in the Dollard. This high turbidity reduces water clarity and sunlight penetration. The water and ecological quality have significantly declined, partly due to constant dredging activities and an excess of sediment. The estuary is an important habitat for species such as seals, spotted redshanks, pied avocets, and common scoters. Seagrass meadows, such as those on the Hond-Paap tidal flat, have been decimated, with very limited plant density and coverage. The area faces ongoing challenges from shipping channel maintenance, with plans for deepening posing risks of further water quality deterioration. The overall aesthetic is of a large, dynamic, and ecologically stressed tidal environment where fresh and saltwater converge.
