stream

Hello everyone!
It is now time for us to spruce up the still loveless garden!
We had a small pond with a stream in mind, however, we are standing there clueless about how to implement such a thing and I don’t like stumbling into ill-conceived projects that fail in the end due to the execution, or something doesn’t work because something wasn’t taken into account...
Is there anyone here who has done such a project themselves or has knowledge about it?
I would be very grateful for a few tips!

Best regards

In my parents' garden, there is a pond. In the pond, there is a submersible pump that feeds water through a hose into the watercourse. The watercourse starts at a small rock garden and then winds around the rock garden with a slope towards the pond. The watercourse next to the rock garden is partly concreted (the lower part) and decorated with stones on top - the lower part is simply protected by pond liner. The kids love the watercourse and sail boats there, build dams, etc.

Sounds cool. Got a photo?
