The Long Lake was an oval-shaped lake situated at the confluence of the Forest River and the northern reaches of the Celduin (River Running) south of the Lonely Mountain. The town of Esgaroth or "Laketown" was (twice) built entirely upon the lake itself, which thus formed a natural moat.
The lake was about twenty miles from north to south and about five miles from east to west.
