Association of Drainage Authorities: Administrative Boundaries - Internal Drainage Districts in England
Summary
PLEASE NOTE: This data has been published by the Environment Agency on behalf of the Association of Drainage Authorities. © Association of Drainage Authorities copyright and/or database right 2020. All rights reserved.
Under the Land Drainage Act 1991, internal drainage districts are areas defined as deriving benefit or avoiding danger as a result of drainage operations. Each internal drainage board (IDB) is a local independent public body that manages water levels in the corresponding internal drainage district. IDBs undertake works to reducing flood risk to people and property, and manage water levels for agricultural needs and for the protection and enhancement of the environment within their district. IDBs are defined as a type of Risk Management Authority under the Flood & Water Management Act 2010. Whilst indicative, the data is the most comprehensive and consistent national dataset of internal drainage district boundaries in England.

- Initially based upon information gathered from internal drainage boards including GIS layers and hard copy data (scans of documents etc).

All IDBs in England have given their consent to ADA to publish these indicative boundaries under an Open Government Licence. Extra GIS data from the Environment Agency regarding the River Arun Internal Drainage District was then included.
