The Loddon catchment covers an area of 680 square kilometres across the counties of
    Hampshire, Berkshire and Surrey.

    The River Loddon itself arises from chalk fed springs in Basingstoke and flows north easterly over chalk and clay before joining the Thames near Wargrave. There are three main tributaries, the River Whitewater, River Hart and River Blackwater. One of the defining features of the Loddon catchment is the varied geology through which the rivers flow. As well as the chalk and clays this includes the acid sands and gravels in the east of the catchment. This varied geology has resulted in a matrix of different habitat types, supporting a diverse range of species.

    The Loddon catchment is predominantly rural with much of the catchment being used for agriculture. Urban and suburban development accounts for 39% of the land area with the main urban centres being Basingstoke, the east of Reading, Bracknell, Wokingham and the Camberley-
    Farnborough-Aldershot conurbation.

    Environment Agency investigations show that physical modifications, pollution from urban and rural areas, and waste water are key challenges to the water environment in the Loddon catchment. Further proposed development is a key factor affecting many issues in the catchment.

    The host of the Loddon Catchment Partnership is the Hampshire and Isle of Wight Wildlife Trust.


    Building Partnership & Engaging Stakeholders

    There is a great deal of engagement from existing groups and organisations within the catchment and these are currently being formalised into a catchment partnership.

    Information about data and evidence work coming soon.
    Information about delivery methods and projects coming soon.


    This partnership is being hosted by the Hampshire and Isle of Wight Wildlife Trust. Information about partners in the catchment coming soon.

Thames Info

The Thames RBD covers an area of over 16,000 sq km from the source of the River Thames in Gloucestershire through London to the North Sea. Dominated by Greater London, the eastern and northern parts of the river basin district are heavily urbanised, whereas the area to the west of London has considerable areas of rural land. The Thames RBD is one of the driest in the UK, with rainfall levels below the national average, however the River Thames is an important water source, providing around two-thirds of London's drinking water. Even though it is one of the most densely populated and urbanised parts of the UK, agriculture remains one of the most important industries in the landscape. Farming varies from intensive fruit and vegetable farming to mechanised arable farming on chalk to dairy and beef farming on grassland.


The Catchment-Based Approach website is designed to showcase the work of catchment partnerships aross England and Wales and to encourage the sharing and adoption of best practice in stakeholder-led catchment managment planning, delivery and evaluation.
