- Its original name was Nenuial, or Lake Nenuial, meaning "Lake of Twilight". Ages since this lake is mentioned several times in connection to Evendim, Annúminas, and for being the greatest contributory to Baranduin (Brandywine River). However, it is not given any prominence in Tolkien's work, neither does it play more than the scenery within Lotro, though a gorgeous looking one.
- It was Elendil who founded the great city of Annúminas at the southern shores of Lake Nenuial after the ruin of Númenor. — The Silmarillion
- Lake Nenuial is mentioned in connection to visitors such as Galadriel and Celeborn: "When they entered that region there were many Noldor in their following, together with Grey-elves and Green-elves; and for a while they dwelt in the country about Lake Nenuial (Evendim, north of the Shire). Celeborn and Galadriel came to be regarded as Lord and Lady of the Eldar in Eriador." This happened during the first millennia of the Second Age. — The Book of Unfinished Tales
