What happens at Arlington Reservoir?

Arlington Reservoir is important for water storage, as it provides water for thousands of South East Water’s customers.

Arlington Reservoir was completed in 1971 and can supply 23 million litres of water daily to the Eastbourne, , Hailsham and Heathfield areas.

The reservoir was formed by cutting off a meander in the River Cuckmere with a concrete faced earth dam. The underlying clay gives a natural watertight base.

During excavations several interesting animal remains were found including a mammoth tusk, a bison horn and the skull of a woolly rhinoceros dating from 250, 000 years ago.

Apart from its main water resource function, the beautiful tranquil setting of the reservoir makes it an important area for quiet informal activities such as walking, riding, angling and nature study. Why is Arlington Reservoir here?

Increasing demand for water in the early 1970’s meant that new sources of water were needed in the area and the decision was taken to build a pumped storage reservoir at Arlington.

Construction began in 1969. Spoil from the construction works was spread across the site, creating the beautiful rolling hill landscape we see today.

The reservoir also serves as a successful trout fishery. Fishing takes place by permit only between February and October, (further information can be obtained from Arlington fishing lodge on 01323 870810) .
