Works to start on de-watering and de-silting of the lake at Boston Manor Park - 8 October 2021

What's going to happen to the wildlife?

  • Fish and terrapins will be relocated as part of this process.
  • The small waterfowl will naturally relocate themselves as the water levels lower and we will create a secure fenced route to provide guidance down to the river.
  • The swans will be re-homed for their protection for the duration of the works by the Swan Support organization and returned to the restored lake.
  • We ask all dog owners using the woodland area to keep dogs on leads during this time to prevent any harm coming to local wildlife.

Why is this happening?

Due to the dense tree canopy over the water, the lake and its margins have been ecologically degraded, and significant amounts of silt build-up and a lack of water circulation has led to fish deaths, especially in high temperatures over the summer.

These works will ultimately improve the lake and surrounding area not just for visitors but for crucially for wildlife.

How will de-watering and de-silting the lake improve the area?

  • Careful and selective tree thinning will allow the remaining trees to grow into healthy specimens, reducing leaf litter and allowing light to penetrate the water and air currents across the water’s surface to increase oxygen levels.
  • This will improve the water quality for fish, waterfowl, birds, insects, invertebrates and amphibians.
  • We will also improve the lake edge and railings, secure the boundary and improve its appearance.
