Watercourses are a vital part of our environment and play important environmental functions. If you have a watercourse on your land, there are rules that may affect what you can and cannot do in and around the waterway.  The rules vary, depending on what type of watercourse you have.

We’ve produced this Watercourse guide to help you determine whether a watercourse is a river, ephemeral watercourse, highly modified river or stream, or artificial watercourse. 

Highly modified waterways

Highly modified waterways (which are sometimes called ‘drains’) are very important ecological habitats. We’ve produced this guide to help you understand your responsibilities if you want to do any work in these waterways:

Watercourse maps

Highly modified rivers and streams have been mapped in some parts of the region (where there is a high concentration of these watercourse types). Have a look at the maps.
