Hydrographic reference resulting from the ministerial instruction of 03 June 2015 of the department of Essonne — rivers—

As part of the Government’s instruction of 3 June 2015 on the development of river mapping, DDT developed, in conjunction with the National Water and Aquatic Environments Office, a map of rivers in the Essonne department. The purpose of this map is to enable all users to share the knowledge available to date to differentiate rivers from other flows. The objective of this map is to allow the application of Articles L.214-1 to L.2014-6 of the Environmental Code.
