Slightly upstream from its mouth and through meanders and shoals , the Cávado River was no longer navigable. In the late 18 th century, queen Maria I,according to other decisions of the same order, approved the works to remove one of the meanders of the river.The majority of the people approved such works,since it did not only to serve the navigability of the river, but they were also useful for agriculture. The only problem was that it involved the demolition of some watermillsmwhich naturally displeasead the locals.Nevertheless,the wall was built ,transforming the meander of Cávado in what became locally call as "the old river" the wall,known as Marachão.(dyke).
