Brent Reservoir (Welsh Harp)

Brent Reservoir is a Site of Special Scientific Interest, with the open water and associated habitats supporting an unusually large selection of wetland birds and plants for an inner city reservoir.

In November 2022, with £55,000 funding from the Mayor of London's Grow Back Greener Fund, we installed new floating ecosystems to provide nesting bird habitat and improve water quality.

The artificial islands – which have been specially designed to support and protect Brent Reservoir's important population of great crested grebe – can be easily viewed from Cool Oak Bridge or the nearby picnic area.

Things to see and do

This is a Site of Special Scientific Interest. The standing open water and associated habitats such as willow car, and fen and marsh support a diverse set of wetland birds - little grebes, great crested grebes, willow warbler - and ducks of course!

While the wetlands areas support plants including: lesser pond-sedge, water forget-me-not, branched bur-reed, marsh woundwort, water-plantain, flowering rush, water dock and lesser reedmace.
