It's probably on privately owned land or something, I HATE that...TRESPASS FOR ANDRASTE! 
It's got a tourist area...and a yacht club now:

Drunk Quizzy: VARRIC MY FRIEND, WITH ME TO THE LAKE! LET'S GO YACHTING FOR ANDRASTE!
Varric: Um, Cadash, are you sure you're feeling alright?
DQ: Fine as you please, why you you ask?
Varric: First, try to remind me later exactly what it was Solas offered you to drink. Secondly, what in blue blazes is a yacht?!?
DQ: A reeeallly big boat, for rich people. Where they can dance and sing and drink on the water!
Varric: That...sounds like a meeting with the Merchant's Guild. On water. Congratulations Cadash, you've managed to give me a bigger nightmare than the Fear Demons.
DQ&Sera (in unison): Biiiig...booooat.
