A brutal negative impact on the economy, society and the environment is the final conclusion of the report made by Ecologistas en Acción about the reservoir project to be built on the Cega River.
The report highlights the lack of efficiency of the work when it comes to storing water, as stated by Santiago Martín Barajas, responsible for the confederal water area of this environmental association “we are facing a very ineffective work. A reservoir is more efficient when it stores a lot of water with a small flooded area. What is happening? As we are in a very flat area, we find that this reservoir that we intend to build would have 40 hectometres of capacity, flooding 700 hectares. In Spain there are many reservoirs that flood less land with a capacity ten times higher ”.
This reservoir would cause a serious environmental impact since it would end up with an important bird protection area where the imperial eagle or the black stork nest and with an area of 700 hectares of resin pine that would also cause economic losses to the municipalities that live on resources such as resin or wood.
On the other hand, it would motivate a social problem of mouth water supply for many nuclei that now drink from Cega “the towns in this area have good quality water since they are supplied by springs that are filtered with sand, with a production of important water. Now five municipalities are supplied, a sixth nucleus will now be supplied, which is Lastras de Cuéllar. And with the reservoir, these springs would be flooded and disappear ”, commented Martín Barajas.
Ecologists do not share the arguments for its construction, which ensures the recharge of the Arenales aquifer, important for the Cuéllar region for 4,000 hectares of irrigation, causing a disaster to cover another with the emptying of this water reserve.
That is why they demand that the administrations definitively renounce this reservoir that was projected in 1917, that the Duero Hydrographic Confederation withdrew in 2003 due to a possible negative environmental declaration and that it was reactivated in 2015 within the Duero hydrological plan, currently being processed in the drafting of the draft.
