I'm afraid I've fallen at the first hurdle.

I followed the Garonne on Google Maps downstream (i.e. towards the
aqueduct) from the the projection of the line of the branch from Le
Passage lock to the river bank for a long way, and could see no bridge
labelled as carrying the D931, nor any evidence of a weir.

Sorry but that could be my fault as I meant follow it down the page
not downstream!

However, when I followed it *upstream*, I soon found a weir some way
above the N21 bridge (Pont de Pierre).  This weir has what looks very
much like a lock cut around the left end of it.  Is this actually the
spot shown in your last photo?  There seems to be a little island by
the downstream end of the cut that might be what the guy in the photo
was standing on.  Although it doesn't quite explain how he got there,
or the waterfall, maybe.

Yes, I am sure that this is the place of the last photo.


Switch to the Sat picture and zoom in to the left hand side of the barrage and
you can see what looks to me like a “cut”.  

When I opened Ged's link, it showed the photo with a street names
overlay.  Or is that just my local setting?

You should have a tab marked satellite to make you from a plan to a
photo.


Also I'm confused by the section of the article that says that the
feeder joined the canal "downstream of the fourth lock below Passage".
The branch doesn't do that.  Or did the article mean "at the bottom of
the four locks flight rising to the aqueduct", which *is* where the
branch joins the canal?  I wouldn't have thought the article author
would have written it that way he did if he meant that. Unless
"Passage" is what he calls the aqueduct, of course.

I think I can clarify this, when you cross the Pont Canal du Agen you
are entering the separate community of Le Passage and the 4 lock
flight is within its boundary.


Another link to La Depeche – dating from September 2006 – gives some
more specific dates of its use that I was surprised at.

http://www.ladepeche.fr/article/2006/09/07/51944-Agen-Ils-veulent-sau...

That article describes a breach in the weir, which is clearly visible
(actually now two breaches).  

OK.  My conclusion at present is that the weir I can see *is*
Beauregard.  There is evidence of a lock cut bypassing it, and that is
what your last picture shows.  The cut once did not rejoin the river
below the weir as it does now, but originally went on to the Le
Passage lock.  Its purpose was both navigation and to feed the canal
below the aqueduct flight (the flow through the lock visible in your
first photo is feed water, not a leak).  

I still need to visit the Archives to try and confirm dates and exact
routes but I am hopeful that there will be some photographic evidence
in existence that I can copy.

I'm on the edge of my seat.


Don't let go !!
