Lake Öreg is a historic artificial lake in Tata, Hungary, created in the 14th century by damming the Által-ér stream. It serves as a vital Ramsar site, providing a critical stopover for tens of thousands of migratory wild geese during autumn and winter. The lake's shoreline is dominated by the medieval Tata Castle, which sits directly on the water's edge. The surrounding parklands are part of the Tata Landscape Protection Area. It functions as a multipurpose basin for both ecological conservation and recreational water activities. The lake bottom was historically utilized for fish farming, a tradition that influences the regional gastronomy.
