Dannemarche reservoir is one of six rainwater storage reservoirs on Jersey.
When full, the six reservoirs hold enough useable water to provide approximately 110 days of supply to the Island.
Commissioned in 1909 the dam is over 70 metres long and nearly 8 metres high.
The reservoir can hold 93 mega litres (over 20 million gallons).
