The claim says Leonardo da Vinci developed the first chamber lock in 1497. The available historical sources contradict both parts of that statement.

• The Canal & River Trust's history of canal locks states that "The first lock with gates at both ends was built in Holland in 1373" and separately says that "In the 15th century Leonardo da Vinci invented the double mitre lock". That means Leonardo is being credited with an improvement in lock-gate design, not with inventing the first chamber/pound lock.
• The Museo Nazionale Scienza e Tecnologia Leonardo da Vinci explains that Leonardo's drawing of the San Marco lock dates to around 1506, and that the relevant stretch of the Naviglio Martesana was made navigable through the construction of three locks by Bartolomeo Della Valle. The museum adds that Leonardo's study may have been an improvement to the gates or a survey after construction. That directly contradicts the idea that Leonardo created a first chamber lock in 1497.

So the sentence overstates Leonardo's role. A historically supportable formulation would be that Leonardo is associated with double mitre gates / improvements to lock design, while chamber locks already existed earlier.
