Re: Tā ir, kad sienās dzīvo "zaļie"
What has been destroyed, at least since the year 2000, are small river barriers: structures that interrupt the flow of rivers and are mostly weirs and small dams only a few meters high that have become obsolete or are no longer in use. These structures do not retain water like a reservoir does; instead, they were used to raise the water level and divert the flow to other places, for example, to facilitate the irrigation of nearby plots. In this article by Maldita.es, we explain the infrastructures demolished in the province of Valencia to debunk the claim that “four reservoirs have been demolished.”
The Ministry for the Ecological Transition and Demographic Challenge (MITECO) publishes the number of infrastructures removed by hydrographic demarcation and year. In the case of the Júcar River Basin, the most affected by these floods and where the province of Valencia is located, 28 infrastructures have been demolished since the year 2000. On MITECO’s geoportal, it is possible to see each of these infrastructures along with the date of demolition, the use of the structure, and its height; in some cases, observations are provided on who funded the demolition or the reason for it. None of these infrastructures were dams or reservoirs.
The tallest infrastructure among those demolished is the El Retorno weir, measuring 7.35 meters, a considerable height but still less than the dams of the smallest reservoirs in the Júcar: El Regajo (6 hm³, with a 28-meter dam) and Algar (6 hm³, with a 49-meter dam).
Additionally, there are six demolished structures that are referred to as “dam of”: Albaladejito, La Hoz, Las Hoyas, Las Pericas, Los Garridos, and Narboneta. None of these structures were reservoir dams, as can be seen on both MITECO’s geoportal and Google Maps images (with links to where each structure was located).
