Starters of change (11) Water

Alange

The upper image corresponds to the village of Alange, in the Spanish province of Badajoz. The dam was completed in 1992, with a wall 67 m high (from foundation) and 720 m long, so what until then was just a village over the Matachel river became a space marked by water and a new coastline. This is no doubt a project beyond the means of a small municipality, and was managed by the Guadiana Water Board. This action produces a new landscape that allows the use of water for irrigation (in lower lands there is a wide agrarian plain) and electricity production.

The reservoir has a catchment basin of 2.545 sq km (which is equivalent to 60% of Rhode Island), and its water surface, of some 35 sq km, is marked by some islands which display the geology of the area. The areas that were to be underwater were cleaned of all vegetation, so when the water level changes sometimes the shores look rather arid, in contrast with a much greener area of lands above water.

Water has brought relevant change; a neighborhood was moved as its precedent site was flooded, some new buildings respond to the new landscape, and it is fair to think that the payments to the owners of land taken to be submerged must have somehow influenced the local economy. There sure was an impact due to the flooding of the lower valley agrarian land, usually a fertile one. Over a stretch, the new layout of the road goes between the urban edge and the water, but its physical configuration is not very attractive. Water has become the central element of an area of the Natura 2000 European Nature considered a Relevant Birds Area; birds have become users of the reservoir. But people are becoming less relevant in number; there were 2.031 residents in 1996, and in 2014 this number fell to 1.946.
