At Megree, thirty miles further down, its width is eighty yards.

In spring and early summer the stream receives enormous accessions from the spring rains and the melting of the snows, which produce floods that often cause great damage to the lands and villages along the valley.

Hence the difficulty of maintaining bridges over the Aras, which was noted as early as the time of Augustus, and is attested by the ruins of many such structures remaining along its course.

Still, there are at the present day at least three bridges over the stream--one, which has been already mentioned, at Keupri-Kieui, another a little above Nakshivan, and the third at Khudoperinski, a little below Megree.

The length of the Aras, including only main windings, is 500 miles.
The Kizil-Uzen, or (as it is called in the lower part of its course) the Sefid-Rud, is a stream of less size than the Aras, but more important to Media, within which lies almost the whole of its basin.
