The La Aldehuela district was
built at the end of the 40’s to house the
workers from the power station.
The power station began operations
in 1950. It used water from the dam for its closed
circuit refrigeration system and was fed coal
from the mines which was transported by means
of aerial cables. In 1958 a third generator was
installed at the power station in order to increase
its capacity but the mines in the area were unable
to supply enough coal and then extra coal had
to be brought in by road from other neighbouring
coal mines. The power station closed down in 1982.
Nowadays the dam has become a nesting centre
for birds such as the Great Crested Grebe and
other species which have found an ideal haven
in the reed beds along its banks.
