Creeks and Streams - Spline?

Hi. As most of you know, a very small creek or stream hardly ever has any visible water. It's usually just a line of mud and rocks with a lot of undergrowth and small trees, etc.
That's what I would like to find in a spline form; so that I can mark the trails of these creeks and streams on the map. I can then come back later, and make them bigger and wider where needed, install a small bridge or two - that sort of thing.
Is anyone aware of a spline like this? It does NOT have to cut into the landscape - it's just a brown and green visual trail.
If nothing exists, then next question is how hard would it be to model a spline? I have done some 3D structures, but nothing like a spline.
Any help or tips great appreciated!

Thanks for the (fast!) wealth of suggestions, folks! I found one that will work just fine.
