I ran into a little problem with the Colbinabbin branch where a creek and a major irrigation channel intersect. I was stumped to begin with and Google earth gave only a few clues, but as it was a bit of an engineering marvel there happened to be a photo online which confirmed my suspicion. They built a sump!
There is still a fair amount of tidying up to do around this area and I've now found a use for huge concrete wall splines.
