The Great Ouse, in this catchment, is fed by four main tributaries: \tThe River Cam, which receives water from the River Granta, the South Level Lodes, the River Rhee and Bourn Brook. \tThe River Lark. The Little Ouse and its tributaries which include the Thet and the Sapiston/Black Bourn. The River Wissey. \n\n\nThe area is characterised by the East Anglian Chalklands in the south, Brecklands in the north and the South Level fenland to the west of the area. The catchment is predominantly rural and includes high-grade agricultural land. The main urban areas within the Cam and Ely Ouse are Cambridge, Royston, Saffron Walden, Newmarket, Bury St Edmunds, Ely and Swaffham. The area is rapidly developing. The catchment also supports a number of nationally and internationally important water-related sites that are of exceptional value.","photoAltText":"Roswell former gravel pits looking towards Ely Cathedral, Cambridgeshire","color":"#c71585","data-url":"http://environment.data.gov.uk/catchment-planning/so/ManagementCatchment/3009","web-url":"ManagementCatchment/3009","label":"Cam and Ely Ouse","type":"Management Catchment","subType":"SurfaceWater","gml":"gml/managementcatchment/3009.gml","id":"3009","legend":[{"type":"surface water operational catchment","color":"#00bfff","display":"area"},{"type":"surface water management catchment","color":"#c71585"}]}
