Originally in the legends Lancelot was called "Lancelot du Lac", meaning Lancelot of the Lake, because he was the son of the lady of the Lake, the lady of Avalon. So, the show must mean the lake of Avalon, where Merlin had him rest in peace. It is an indirect connection to the original legends, like the episode "Le Morte d'Arthur". The creators probably do this in order to show the connection between the show and the legend.
