The Senha River is a river on Bajor. The Elestan River branches off from the river. The spires of the Vanadwan Monastery were once visible from the upper Senha River, until the Cardassians began using barges on the river. The monks feared the Cardassians would discover the monastery and so toppled the towers so Vanadwan could not be seen from the river.
