Legal FrameRoyal Decree 1265/2005, of October 21st, by which exceptional administrative measures are adopted for the management of hydrological resources and for the correction of drought effects in the hydrological basins of rivers Júcar, Segura and Tajo, extended until 30th November 2008 by Royal Decree-Law 9/2007, of October 5th.

The Permanent Commission of the Governing Board, constituted on December 1st 2005, has developed a detailed follow-up of the drought evolution, meeting up monthly. Thanks to its constitution, public participation is made effective in drought management.

Use reduction 2007-08

Objective: Reducing extractions in the middle section of the Júcar river, both in surface water and in groundwater with a greater effect on the river flow.

2007 Rights acquisition through reduction of irrigated surface. 2008 Rights acquisition by using less water-consuming crops (spring crops).
