Sirannon

The Gate-stream of Khazad-dûm

The course of the Sirannon (conjectural)2
The course of the Sirannon (conjectural)2

A stream or small river that rose from springs near the West-gate of Moria, and was therefore known as the Gate-stream (or, in Elvish, the Sirannon). From there it ran down a series of waterfalls known as the Stair Falls before continuing westward. The road from old Khazad-dûm to Eregion followed the course of the Sirannon for at least several miles, and it may be that Ost-in-Edhil, the chief city of the Elves of Eregion, was built on the river.3 The waters of the Sirannon presumably flowed into Glanduin, the only significant river in this part of Middle-earth, and thence into the Gwathló and on to the Great Sea.

In the closing years of the Third Age, after the occupation of Moria by creatures of Sauron, the upper waters of the Gate-steam were dammed and the Sirannon itself was reduced to a mere trickle. This created a great pool outside the West-gate, which was guarded by a dangerous and mysterious being known only as the Watcher in the Water.


Notes

1

The stream of Sirannon is not shown on any map, so we're reliant on textual descriptions to understand its course from Moria. The stream's outflow is never specifically described, but given the existence of the river Glanduin fifty miles away or less, and the lack of any other major rivers nearby, it seems inevitable that the waters of Sirannon must have emptied into Glanduin at some point.

2

As noted above, we have very limited information about the course of the Sirannon. Indeed, all we can say for certain is that its source was by the West-gate of Moria. Realistically, it must have followed a line something like that shown on this map, though its precise course is entirely unknown. The river is shown as a dashed line on the map to emphasise this fact.

3

We don't know exactly where Ost-in-Edhil stood, but the fact that the road towards it ran along the Sirannon, coupled with the clear practical value of building a city on a watercourse, gives at least some credence to the possibility that the city stood on the river.
