This data shows Drainage District (DD) Channels constructed under a number of drainage and navigation acts from 1842 to the 1930s, that local authorities have a statutory obligation to maintain. These channels are either modified watercourses or constructed channels/drains to enhance the conveyance or constructed to modify the flow regime in an area. Drainage Districts were carried out under a number of drainage and navigation acts from 1842 to the 1930s to improve land for for agricultural purposes.
Purpose: This data has been developed to support the maintenance of Drainage Districts carried out under a number of drainage and navigation acts from 1842 to the 1930s. This work was initially carried out by the Commissioners of Public Works to improve land for agricultural purposes. Local authorities are now charged with the responsibility to maintain the Drainage Districts. Maps and descriptive documents, known as the Award, were created when these schemes were completed to describe the work carried out.
