The lake is situated in the middle of the town of Tata. Adjoining the South-east quarter of the lake is a wooded area. It is fed by the Által-brook (Hungarian: Által-ér) from the south-east, which then leaves it in a Northerly direction through the town until it eventually reaches the Danube.
On the lake's shores lie Tata Castle and the Esterházy Palace.
