Spain still has dozens of reservoirs that cannot be used because literally no one has installed pipes

Dozens of Spanish reservoirs remain unused because the pipelines and secondary channels needed to move the water were never built.

Projects such as Siles and Rules have sat for years in limbo amid jurisdiction disputes, permits, and administrative delays.

The article says the same problem affects other dams, including Alcolea, Mularroya, and Castrovido, across several provinces.
