In order to determine the precise location of the boundary line in the main navigable channel, namely, the line of deepest soundings, as it existed at the dates of independence, the Chamber based itself on a report prepared in 1970 at the request of the Governments of Dahomey, Mali, Niger and Nigeria by the Dutch company Netherlands Engineering Consultants.
