'''Lake Marathon''' or the '''Marathon Reservoir''' (Greek: ''Limnis Marathonos''')a is a water supply reservoir formed from the construction of Marathon Dam at the junction of Charadros and Varnavas Torrents near the town of [[Marathon]], in [[Greece]]. Since 1931 when the reservoir became operational was the primary the water supply facility for Athens until 1959 when water supply from [[Yliki Lake]] and Mornos Reservoir (operational since 1981) used, today is a backup source for water supply of Athens.

The area of the lake at the height of the spilway of the dam is 2.45 square kilometres, the maximum deth is 54 m , the lake concetrates water from a watershed of 118 square kilometres with an average runoff of 14,400,000.0 m³ per year in an average rainfall of 580mm per year (standard deviation 135mm), the average inbound volume is 12,000,000.0 m³ per year and the maximum reservoir capacity is 41,000,000.0 m³ (effective volume 34,000,000.0 m³).

The dam has a maximum height (from foundation to crest) 54m, maximum width 28m at base and 4.5 m at crest, length 285m , crest altimeter 227 m above sea level, toe altimeter 173 m above sea level (at lower point), the spilway is at 223 m above sea level and has a disgarge of 520 m³/s. The dam is costructed from concrete and is a gravity dam and is considered unique worldwide because of the external cladding of white pentelikon marble (the same marble used in constuction of the [[Parthenon]] and all the other buildings in the [[Acropolis]]. The dam constucted from the American firm ULEN (which had, in a [[BOT]] type contract, the ownership of water supply company of [[Athens]] until [[1974]]) due to increased water supply needs from the rapid increasing of population of Athens from the huge influx of refugees from [[Asia Minor]] in after the end of Greek - Turkish war in [[1922]]. The construction lasted from [[1926]] to [[1929]].
