Children at Marathon dam
The artificial lake of Marathon, created by the historical dam (created 1926-1929) at the junction of Charadros and Varnavas Torrents near the town of Marathon, was the primary water supply for Athens until 1959.
The area of the lake is 2450 acres and its maximum depth reaches 54 meters. The lake collects water from an area called the drainage basin area of 118 sq. km., with an average runoff of 14.400.000 m³ per year, with average annual rainfall of about 580 mm. The average inbound volume of the lake is 12.000.000 m³, while the maximum reservoir capacity is 41.000.000 m³ (of which only 34 million can be drawn).
The crest of the dam has a maximum height of 227 meters above sea level. The Marathon dam was built by U.S. company ULEN (which maintained by contract, the ownership of the water supply company of Athens until 1974)
