About the reserve

This large expanse of water is a valuable refuge for waterfowl, including blacknecked grebe. An important site for large numbers of wintering ducks, particularly mallard, shoveler, teal, wigeon and goldeneye. The area is of national importance for its summer populations of pochard, tufted duck and common tern. The marginal vegetation supports many breeding bird species such as reed bunting and sedge warbler. Around the margins of the reservoir are large marshy areas where many species of marsh plants flourish, including great reedmace, reed canary grass, phragmites and various sedges.

Hilfield Park Reservoir is owned by Affinity Water and managed by the Trust.
