Project summary

Edit project overview to modify the project summary.

In May 2006 the low level of the reservoir Buendia caused that the dam used to supply the town of Alcocer became an insuperable obstacle to the cyprinids, which prompted the Provincial Delegation of MN and D.R. of the province of Cuenca and various groups, asked for help from the Tagus River Basin. The main solution was the construction of a fish scale to overcome the weir and allow passage upstream of cyprinids.
