Tweed Estuary SAC
This is an estuary which feeds into the North Sea. The water quality is classified as excellent throughout. Lots of fish swim through here, including the rare allis shad. Migratory Atlantic salmon and occasional river lamprey and sea lamprey also use these waters. Sandstell Point, at the mouth of the estuary, is a wide spit of clean mobile sand on which lots of crustaceans live.
