Recent findings (audit lane, verbatim)

Albert Canal — The claim that the German construction company Hochtief worked on the canal between 1930 and 1934 is not supported by standard historical sources and is likely a factual error.

Amsterdam–Rhine Canal — The claim that the southern part from the Lek to Tiel opened in 1938 is incorrect; the northern part from Amsterdam to the Lek opened in 1938, and the southern part to Tiel was completed later.

Amsterdam–Rhine Canal — The statement that the canal was built to replace the Merwede Canal is misleading; the Amsterdam–Rhine Canal largely replaced and incorporated the Merwede Canal, using its widened bed for the northern section.

Buckingham Canal — The intermediate name 'Lord Clive's Canal' is not supported by reliable historical records; the canal was known as Cochrane's Canal until 1878.

Buckingham Canal — The initial construction in 1806 only extended from Madras to Ennore, not the full 420 km from Gudivada Kalava to Marakkanam.

Bydgoszcz Canal — The entry states the canal length as 24.7 km in the INTRO and STATS, but the LORE section says it was 26.7 km long. The correct length is 24.7 km.

Bydgoszcz Canal — The LORE section claims the canal was 26.7 km long with 10 wooden locks. Historically, the original length was 24.7 km, not 26.7 km.
