I'm sure people in here will know.

There is an issue with the Panama Canal because of lack of water.

On the Thames (slightly different scale) the water come in at the "high"
end and is let out through a series of locks to the tidal Thames.

Why can't the Panama Canal work on that basis?

It does. The problem is the lack of water at the
high end and the much higher volume of water
involved to the much higher volume of massive
ships moving thru the canal.

Because the high point of the Panama is in the middle.
Even the Thames has trouble with low water in dry periods. Midlands
canals with their up and down profile regularly have limits of use in
dry periods, they work on the same principle as the Panama, a large
lake/store of water at the summit. In Victorian times, the water at the
bottom would be pumped back to the store at the top, but that doesnt
happen now.

Bigger ships using bigger locks and using a larger amount of water.

The Panama canal is higher in the middle, and much very higher than high
tide at the oceans at either end.

Where is the high end of the Panama Canal?

About a decade ago they deepened and widened the canal, so it takes more
water to operate the locks.

Sea level on the Pacific side is higher than on the Atlantic side by a
whole 8 inches! Loads of other info on wiki:

Both ends are low, it is the middle that is high and fed from a lake.

Many thank for all the replies :-)

I didn't realise the high spot was in the middle that explains it!

I like the animation of how locks work, first graphical program I wrote on
my BBC micro was to explain that to my daughter.

Didn't they also construct more (pumped) side ponds?

Yes I know (and knew). I was asking Jeff where he thought the high end was. In
fact, the lake isn't just tapped for water to run the canal. It splits the
canal into two sections and you have a 20 mile section of the lake to cross,
in the middle. So the Panama canal is like 2 x River Thames back-to-back, and
the lake provides water for both sections. So the canal and the Thames operate
the same way; the issue is a shortage of rainfall in the area.

With the "new" supermax locks, they do pump between locks so as to reuse
some of the water. The can't do that on the older ones though.

And a small sip in a big lock uses the same amount of water as a big ship.

Nope, the small ship displaces less water and a lock
that can take a big ship needs much more water to fill it.

Another counter-intuitive fact - the western-most end of the canal meets
the Caribbean, and the eastern-most end meets the Pacific.
