Description: The statutory main river Line Variation dataset defines changes to the statutory main river map.The statutory main river map is a dataset that defines statutory watercourses designated by the Environment Agency as main rivers.'Main rivers' are usually larger streams and rivers, but some of them are small watercourses of significance. They include certain structures that control or regulate the flow of water in, into or out of the channel. We have permissive powers, but not a duty, to carry out maintenance, improvement or construction work on designated main rivers. We have powers to regulate the activities of others affecting rivers and their flood plains under the Environmental Permitting Regulations, the Water Resources Act 1991 and our land drainage byelaws. All other watercourses are 'ordinary watercourses'. 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. They also have powers to regulate works under the provisions of the Land Drainage Act 1991 and local byelaws.
