Lake Achinos
Lake Achinos spread across the lower Strymon valley north of Amphipolis, a shallow expanse fed by the river before it reached the Aegean. Known in antiquity as Lake Cercinitis, it formed part of a waterway linking the Strymonic Gulf with the interior. Its waters and those of the river were rich in fish; the Strymon's eels were particularly celebrated in ancient accounts. The lake expanded and contracted with the changing flow of the river and the seasons.
