operational updates

Walthamstow Wetlands is a Thames Water operational site which serves 3.5 million people with drinking water. To ensure clean and safe drinking water, there will be times when maintenance works will need to be carried out onsite. To keep visitors safe, these works will occasionally affect the access to Walthamstow Wetlands and the various activities allowed onsite and there will be occasions when areas of the site will need to be closed. Whilst operational work is taking place onsite, we kindly ask visitors to take care and avoid entering the affected area.

Below you will find details on upcoming operational works that will be taking place at Walthamstow Wetlands. Please note, these dates are subject to change and we would ask all visitors to check back to this page for the most up to date information.


The south side of Walthamstow Wetlands has been closed early today (Thursday 10th October) due to operational works with heavy machinery on the East Warwick Reservoir. We apologise for any inconvenience.


With the end of the British summer time and the shortening days, Walthamstow Wetlands will be open between 9.30am - 4pm daily starting from Tuesday 1st October. These winter opening times will be in place until spring 2020. 


As a nature reserve, we have to occasionally limit access to certain areas to protect nesting birds or special wildlife habitats. Please stay on the marked paths and trails and look out for signs - they are there to protect both you and the wildlife.

Currently the path running along Reservoirs 4 & 5 is closed due to the area being used by moutling tufted duck.
