Here's what I've done:
Rivers made at just 1 x 50m pixel, only connected at bends by the corners, in other words the smallest river that can be done.
I copied the layer (three times so far).
Layer 1 - Gaussian Blur 1.0. On its own this caused a lot of gaps in the river and it appeared 'shallow'.
Layer 2 - Gaussian Blur 0.4 and merged with Layer 1. Still a few gaps but overall not a bad result.
Layer 3 - No blur; simply merged with the other two. Here's the result:

As you can see from the grid the average width is about 100m, but every now and then these very thin North/South strips appear, width about 25m. I was hoping that the addition of Layer 3 might widen them out a bit but no luck. As I am trying to create streams I don't really mind, but it only ever happens N-S.
Just about all of the gaps have gone, but the blur has eliminated a lot of the islands that I had put in - two pixels of land between streams. These look like shallow patches.
However, the worst thing about these 'streams' is that vehicles drive straight across them, even the 100m wide bits. Is there a minimum width before water acts like it should?
