The sea level difference either side of the Panama Canal is approx.
20 cm (higher on the Pacific side) - see for example, Pugh, D.T.
1987, "Tides, surges and mean sea-level", Wiley.
RLR 1964 datum at Balboa is 3.112 m below the "Tide Staff Zero" which
is itself 12 feet below Panama Canal Precise Level Datum (PLD).
On the Atlantic side, at Coco Solo RLR 1993 is 6.288 m below the
Tide Staff Zero which is itself 2 feet below PLD there.
For the older Cristobal data, RLR 1964 is 6.138 m below the
Tide Staff Zero which is itself 2 feet below PLD.
From inspection of RLR data and from this information, one can
indeed verify that sea level is higher on the Pacific side by
about 20 cm. However, the accuracy of the PLD national levelling
system is unclear.
