The statutory main river map is a 1:10,000 scale spatial (polyline) dataset that defines statutory watercourses designated by Natural Resources Wales as main rivers. The data is for Wales only. '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.

Natural Resources Wales has permissive powers, but not a duty, to carry out maintenance, improvement or construction work on designated main rivers. Natural Resources Wales has 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. Natural Resources Wales undertakes the role of the Internal Drainage Board in Wales for all Internal Drainage Districts.
