Wasn't sure whether to tack this onto the Spital dam thread, but because it's an old/new comparison I thought I'd put it here.
The map is from about 1913 & I've made a couple of additions in red. The live Search view is for comparison. The main change is on the shoreline, which is quite different & shows that a lot of land has been reclaimed; notice how close the shoreline came to Price's Candle works. Incidentally, on the map, H.W.M.O.T. stands for High Water Mark,Ordinary Tides. The red square on the map is the site of the old Stone Quay which was the end of the Storeton Quarry Railway. You can see the tracks leading to it running along the front of Lever's & under the main line. The two tracks at the quay were lifted in 1906, so aren't on the map. It is known that at high tide, barges could tie up on three sides of the quay. Further upstream you can see the dock at Lever's, with a lock at its mouth. Boats of some size (or maybe they were lighters) woud unload cargoes of palm oil etc. here & take away the soap products. Note that the dock is still there today. The other thing I've marked in red is where the natural loop of the stream has been cut off, isolating the old stone quay. See also there was a boatyard & slipway opposite the candle works. There's a pale patch there today. What I don't know & maybe someone could find out is, what is the depth of the old channel at the bridge on New Chester Rd? All that would be needed is a weight on the end of a string; any volunteers? That height would obviously have governed the size of ship which could be used.
The present day view shows great detail in bird's eye view.
I'm sure you could find lots of other changes.http://maps.live.com/default.aspxI don't know why I can't link to the view I want, but I guess you can easily navigate there from here, just zoom in on Bromborough Pool.
