More about the lake

The lake was first dug in the 1700s. It is around 285 metres long by 48 metres wide and is 3.5 metres at its deepest level.

The water in the lake

The lake is filled and refreshed by three sources of water:

  • Natural run-off as it is located at a low point in the park.
  • Ground water harvested through a drainage system installed below the lake liner.
  • Water from the chalk aquifer under the park, which is accessed by a new 76 metre deep borehole.

There is also an outflow into the wet woodland that will, over time, create a new ecologically rich and locally rare habitat. Aquatic planting will take place during spring, to help absorb nutrients and improve the quality of the water. There are three planting shelves in the lake which will help to absorb nutrients.

As the lake has only just been filled initially the water:

  • may look green at first. This is natural and does not necessarily mean that the quality is compromised
  • will be tested regularly. If tests show the water quality has dropped below acceptable levels for swimming, we will let you know. 

Dogs

Please keep dogs out of the lake at all times. This may mean you need to keep your dog on a lead when you’re near the water. Dogs pose a threat to young wildfowl, trample the establishing lakeside planting, reduce the water quality for swimmers and can increase the risk of accidents. Dogs might enjoy other bodies of water in the park – the swales and the river Ravensbourne.
