Hay Guys we are traveling to the pool hole / kalam, the old road cross riau-sumbar.
this pool/kalam hole is located in kampar. Built in 1929 by the dutch colonial government, this street was once a riau cross road to sumbar and since 1994 this pond hole road has been no longer used since the construction of koto panjang hydropower plant and this road has been sunk for the long koto hydropower project and for the road to the sumbar of Riau through a new road that has been built.
