Lambre River Nature · Monfero, Eume, A Coruña Watercourse that drains the western part of Monfero together with its tributary the Lambruxo; it runs hemmed in between riverside woods and under medieval arched bridges before leaving the concello on its way to the ría de Betanzos. It rises at 600 metres above sea level on Mount Pena da Uz, within Monfero itself, and after crossing the municipalities of Villarmayor, Irijoa, Miño and Paderne it flows, after a 15-kilometre course, into the sea at the place of Ponte do Porco, in Miño, on the right bank of the ría de Betanzos. It is a river with an oceanic rainfall regime, and along its course, in Vilarmaior, lies the Guimil reservoir, owned by Unión Fenosa. Its name, already documented in 1092 as flumen Lambre, has been linked to the pre-Roman root that also gave rise to the river Tambre.
