Sirannon was a river in Eriador.

According to the The Atlas of Middle-earth, the river was about one-hundred miles in length.[1] In the late Third Age, it flowed near a knoll by the High or Hollin Road into a pool close to the Doors of Durin.[2]


The Sirannon once flowed from an underground source near the West side of Moria and running along the road that once led to Ost-in-Edhil, it was dammed at an unknown date in the last thousand years of the Third Age, closing off the Doors of Durin from neighboring lands. The foul pool created by the damming of the stream was where the Watcher in the Water lived.

After the War of the Ring and the resettling of Moria by the Dwarves, the stream and the foul pool it ran through was probably cleaned and freed up to flow naturally to its original destination.


Sirannon is a Sindarin word for 'stream-gate'.[3]
