Identify a type of watercourse

Use this service to identify:

• a type of watercourse
• who maintains the watercourse (if you want to carry out work)

If the watercourse is not shown on the map, you can assume it’s an ordinary watercourse.

You can zoom in and out of the map using the plus and minus.
