I posted some time ago about Normandy Hedges (thanks for all the replies! ) and I have been thinking about making a ditch for the same future dio. Anyway, does any one know how to make the little trickle/stream of water that can be seen in most ditches? There just seem to be so many ways, and I have know idea which work best... Thanks!

For small amounts of water you can use some laquer painted on in layers. You can also try two part epoxy in small batches.
