Long Lake

The Long Lake was an oval-shaped lake situated at the confluence of the Forest River and the northern reaches of the River Running, south of the Lonely Mountain.
The lake was about twenty miles from north to south, and at least five miles from east to west at its widest.
== History ==
The town of Lake-town, whose name refers to this lake, was (twice) built entirely upon the lake itself, thus forming a natural moat. After Smaug's demise, his dying body fell into the lake with a mighty crash. Smaug's remains could be seen sticking out of the water from the shore of the lake, but people feared them and treasure-hunters did not dare approach the carcass.
The surrounding areas are set in the immediate aftermath of the Battle of Dale, with Men and Dwarves rebuilding after the siege and remnants of the Easterling army still lurking around.
