Walton Lake

Originally built as a 'balancing lake' for the River Ouzel, Walton Lake is one of the richest spots in Milton Keynes to enjoy wildlife.

What to see and do

Don’t miss

Walton Lake was no longer needed to absorb floodwater once Willen and Caldecotte Lakes were created. The lake was allowed to fill with reeds, creating a very different habitat from the open waters of most of the city's other lakes.

In 2002 the Parks Trust, with funding from Shanks First, built a boardwalk into the reedbed. This wonderful route through the reeds is linked to two birdhides, offering fantastic opportunties to see the bird and waterlife really close-up.

It is the combination of habitats that makes Walton Lake so rich in wildlife. Surrounding the reedbed are ponds and open water, ancient hedgerows and hay meadow, plus the River Ouzel running nearby.

Mature reed bed need a lot of management to keep them in optimum condition. If they are neglected trees will start to invade, drying out the reedbeds until eventually the habitat is lost. To prevent this from happening the reedbed at Walton Lake is maintained by Parks Trust volunteers and contractors, regularly cutting back blocks of weed to create a diverse mosaic of open water, and blocks of reed of different heights

 A series of information panels have been installed around the park, packed with information about the site. The panels have been jointly funded by Shanks First and the Open University, whose headquarters neighbours Walton Lake.


Each year Walton Lake hosts guided walks to explore the wildlife. Particularly popular are events to see the damsel and dragonfly population.For full programme see our events pages.


Look out for reed warbler, reed buntings and water rail, sparrowhawks, green woodpeckers and breeding kestrels. During the summer months the lakeside hums with insect species such as dragon and damselfly. And Walton Lake has a colony of grass-snakes whose shyness makes them hard to spot elsewhere.
