Waterways and Water Transport in Different Countries by J. Stephen Jeans

2. _The canalised river Ijssel_, from the river Lek, opposite to

Ijsselmonde, to Gouda, whence there is canal communication with the river Amstel, to Amsterdam, and also by the old Rhine, _viâ_ Leiden and Haarlem, to Spaandam, to the North Sea Canal. There is a great traffic in the former of these two routes, there being always a great collection of craft at the sluices at Gouda, waiting their turns to pass. Large and improved locks are said to be urgently required at this place. The depth of water on this route is at least six feet.
