Ooo, fun mystery!

My first guess, based on the size/shape of the opening, is accessing a pump for the canal. But I do not, personally, know of an appropriate cement for such an application without lift points in the plug.

The lid is likely required to meet a set of security requirements to prevent tampering, thus must be quite difficult to remove in an apparently remote location.
