The Fens and Anglian system is a collection of rivers in East Anglia in England that are navigable and for which the Environment Agency is the navigation authority.
[1] Many of the rivers drain The Fens between Cambridgeshire and Lincolnshire.
The Environment Agency is organising the Fens Waterways Link a major construction project to link these rivers for navigation.
[2][3] Two East Anglian rivers in the grouping are physically separate from the Fens network.
The Environment Agency supervises craft registration for these rivers.
