About the Lower Ouse catchment
This catchment covers the River Great Ouse valley from Roxton to Earith and its main tributaries Abbotsley/Hen Brook, River Kym, Ellington, Cock and Alconbury Brooks. The River Great Ouse flows through the major towns of St Neots, Huntingdon and St Ives and contributes to their character. Elsewhere the catchment is mainly rural. At Offord, water is taken from the river to supply Grafham Water reservoir. Portholme Meadow, near Huntingdon, is the only designated Special Area of Conservation in the whole of the Upper and Bedford Ouse Management Catchment. This traditionally managed flood meadow is particular important for its plant life.
