Chew Valley Lake



Chew Valley Lake is located south of Bristol in south-west England. It is a large, shallow, artificial reservoir with some fringing reedbeds, carr woodland and grassland. The water conditions are eutrophic and open water plant communities are rather sparse, largely comprising Fennel Pondweed Potamogeton pectinatus and Lesser Pondweed Potamogeton pusillus, Opposite-leaved Pondweed Groenlandia densa and Water-crowfoot Ranunculus spp. On neutral soils around the reservoir, Pepper-saxifrage Silaum silaus, Burnet-saxifrage Pimpinella saxifraga and Devil's-bit Scabious Succisa pratensis occur, and on calcareous soils Fairy Flax Linum catharticum, Dwarf Thistle Cirsium acaule and Salad Burnet Sanguisorba minor subsp. minor are found. The open water of the reservoir and its margins are of greatest value for wintering waterbirds.
