Willen Lake Milton Keynes From Above 

Willen is a district of Milton Keynes, England and is also one of the ancient villages of Buckinghamshire to have been included in the designated area of the New City in 1967. The original village is now a small but important part of the larger district that contains it and to which it gives its name.One of the more important features of the district is a large balancing lake on the River Ouzel, designed to capture flash floods lest they cause problems down stream. The north basin is a wild-life sanctuary and a favourite of migrating aquatic birds. The south basin is for leisure use, favoured by wind surfers and dinghy sailors. The circuit of the lakes is a favoured "fun run".
