Work is due to start this week to clean and refill St James's Park Lake to improve the water quality for wildlife.

Last drained in 1991, the Lake will be emptied in two sections, with a temporary dam built down the middle, in order to give wildlife access to water and to an island at all times. Once the water has been drained, silt will be collected and removed and the condition of the sluice gate and base of the lake will be inspected and repaired if necessary. The reedbeds along the banks of the lake will be protected during the works and may be extended following the project.

Mark Wasilewski, Park Manager of St James's Park said: "Silt, leaves, and other materials have accumulated in the lake and we felt that this would be an appropriate opportunity to drain and clean it. A number of interesting objects have been found in the past including wedding rings, cameras, and umbrellas - so I'm curious to see what turns up this time!"

The project is due for completion towards the end of April 2009.

Notes to Editors

About the project: The Lake is 4.6 hectares and two-metres deep. It will be re-filled from artesian wells situated in St James's Park and each section of the lake will remain empty for between three and four weeks.

About Reedbeds: Reedbeds are important natural habitats that provide shelter, nest sites and food for a wide variety of wildlife. Reedbeds naturally and effectively cleanse water by absorbing nitrates and pollutants through their roots. This creates a more balanced ecology and improves environmental conditions.
