Recent findings (audit lane, verbatim)

Grand Canal (China) — The entry states the Sui dynasty's Grand Canal was completed in 609, but the full system was completed in 611.

Kiel Canal — The entry states the canal was named after Kaiser Wilhelm II's grandfather, but it was named after Kaiser Wilhelm I.

Rhine–Main–Danube Canal — The 'DID YOU KNOW' section claims the canal's summit is 'the highest point reached by commercial watercraft from the sea in Europe,' which is factually incorrect; the highest point is elsewhere.

Rhine–Main–Danube Canal — The 'DID YOU KNOW' section says 'The canal has 16 locks, with lifting heights up to 25 meters,' but the maximum lift height is actually 24.67 m (at Hilpoltstein lock).

Rideau Canal — The first survey of the Rideau route was conducted in 1783 by Lieutenant Gershom French, but it was for Loyalist settlement, not a military route.

Rideau Canal — The 1816 survey was conducted by Lieutenant Joshua Jebb, but he surveyed the Ottawa River, not the Rideau Canal route; the first canal survey of the Rideau route was done by Samuel Clowes in 1823–24.
