The source of the river begun as two unnamed arms in the central Misty Mountains, near an important pass. It then flowed eastwards to the Great River Anduin, which it met in a series of marshes called the Gladden Fields.
Much later during the Third Age some Stoors lived near the streams of Gladden, and from them came Déagol who found the ring, and was killed by Sméagol (Gollum), who long held the Ring. Gollum eventually followed the stream up to its source, ending up in forgotten caves near Goblin-town.
In T.A. 3018 some of the scouts sent out by Elrond after the arrival of the hobbits in Rivendell crossed the Misty Mountains over the pass at the source of the Gladden to seek the wizard Radagast at Rhosgobel, but he was not at home, and they return through the Dimrill Stair.
