Despite that environmental organizations early claimed that the reservoir would affect negatively a large protected area in Mularroya, the construction started anyway in 2008. The environmental impact assessment (EIA) was revoked in 2009, but the construction continued until 2013, when the Spanish Supreme Court stopped the construction, and so it remains since then. In order to bypass the need of an EIA, the Spanish government declared the reservoir object of prime public interest, which might enable the construction to be resumed if compensatory measures are taken. However, the legal battle is not over as the environmentalists claim that this procedure can only be invoked under extraordinary circumstances, which is not the case here. Cost: €128 million plus overrun.
