River Rushdown

A northern tributary of the Anduin

Map of the River Rushdown

A lesser tributary of the Great River Anduin. It rose in the eastern Misty Mountains, not far from the sources of the Hoarwell, though on the other side of the range. The river started as twin torrents rushing down from the mountains (hence its name) though these joined as they flowed into the Vales of Anduin. The combined waters of the Rushdown flowed on to meet the Great River some fifty miles north of the Carrock.

Various related Elvish names are known for this river, of which the most settled form seems (arguably) to be Rhimdath (though the variants Rhibdath and Rhibdad are also recorded). The course of the Rushdown is marked on the maps that accompany The Lord of the Rings, but the river itself is not named there.
