Understanding and improving the water environment across the Adur & Ouse CatchmentRead more
Rivers, wetlands and marine environments are all under pressure. Understanding the issues is key to providing lasting solutions for both people and nature.
Explore the Catchment
Do you know where your local river or stream is? Our map shows the catchment and provides information on the water environment across the whole area.
There are many ways you can help to improve the local environment and we are always keen to get people and business involved in our activities.
What is a catchment?
A catchment is an area of land including hills, farmland, woodlands, towns and villages from which water drains after rainfall. This water flows into streams, rivers, lakes and underground aquifers, eventually flowing into the sea through our estuaries. The water which flows above ground is called surface water and the water that seeps into the soil is called ground water. There are 100 catchment areas in England and Wales, all are different but all are formed on the basic principle that they collect all the rainfall in that area.
Catchments provide a range of benefits for people and wildlife, they provide natural flow to rivers, sustain wetlands and host a diverse array of plants and animals. We use the water collected within the catchment for many things; to drink and use in our homes, produce food, support local industry and provide recreational activities such as angling, canoeing and swimming.
Our Areas of Work

Natural Flood Management
How we work with nature and natural processes across the catchment to reduce the risk of flooding to local communities in our area.
Find out more about how we are supporting the protection of water in the aquifers of the South Downs, a vital supply of drinking water.
This is what we want, natural rivers full of a diverse range of wildlife and able to provide a recreational resource for communities.
