The EA Statutory Main River Map shows the sections of watercourse that are the responsibility of the Environment Agency.
Statutory Main Rivers Map is a spatial (polyline) dataset that defines statutory watercourses in England designated as Main Rivers by the Environment Agency. Watercourses designated as 'main river' are generally the larger arterial watercourses. The Environment Agency has permissive powers, but not a duty, to carry out maintenance, improvement or construction work on designated main rivers. All other open water courses in England are determined by statute as an 'ordinary watercourse'. On these watercourses the Lead Local flood Authority or, if within an Internal Drainage District, the Internal Drainage Board have similar permissive powers to maintain and improve.
