Warkworth Road Waterfall building
 

A couple of pics of the dam/waterfall being built. Perhaps someone on here can expand on its use in the great Warkworth Waterworks scheme of things?
It must have certainly changed things as low tide up by the Butts would have had a lot more mud flats unlike todays' scene

and another, note the old road before it was rebuilt higher

When?
 

I flew down this in a Conor, I always wondered when ( and why ) it was built
