Greyflood

The Greyflood was the name given to the lower reaches of the River Hoarwell, known to the Elves as the Gwathló. The Greyflood flowed southwest from the confluence of the Hoarwell (Mitheithel) with the Glanduin, until it reached the Great Sea at Lond Daer. It formed the border between the regions of Enedwaith in the south and Minhiriath in the north, and took its name from the tree-shadows of the great forest that filled those regions during the Second Age.
