Chew Valley LakeBristol Category Outdoor Activities, For the Family, Nature & Wildlife
Chew Valley Lake is well known for its birds, including internationally important numbers of wildfowl. The Trust reserve is at the southern end of the site and is managed in partnership with Bristol Water.
Breeding birds include great crested and little grebe, gadwall, tufted duck, shoveler and pochard. Hobbies often feed over the area in late summer. When the water level falls, the mud attracts waders such as dunlin, ringed plover and green sandpipers.
Summer sees large populations of dragonflies hunting over the water. These include ruddy darters and, later in the summer, migrant hawkers. Wintering wildfowl include important numbers of shoveler, gadwall, teal and tufted duck. Goosander, great crested grebe and cormorant also occur in large amounts.
The reedbeds are a vital autumn feeding station for reed and sedge warblers prior to their migration. The winter gull roost is a spectacular sight with up to 50,000 or more, mostly of black-headed, common and Mediterranean gull. Chew Valley Lake often attracts rare birds, including osprey, the scarcer grebes, and an American wader or duck appears most years.
