Well out of interest I started poking around the bylaws. Not surprisingly it's rather ambiguous...
Although not mentioned here in the FAQ:
http://www.calgary.ca/UEP/Water/Page...omeowners.aspx
The bylaw itself (
http://www.calgary.ca/CA/city-clerks...5-Drainage.pdf) does seem to state that you can drain from a decorative pond so long as it is less than 3000 litres.
However, elsewhere, it mentions that a decorative pond is defined as "an artificial body of water for ornamental purposes but does not include fish ponds". But then.... nowhere does it say that fish ponds are allowed to be drained into a swale,
but neither does it state "do not".
It does list that
fish themselves can't be put into the drainage. But I can't find anything about water that has touched fish while in your custody.
Confused as ever as to whether the city feels they can fine you for draining a pond into the swales or not.

I know they will gleefully fine you if you don't keep it clean enough or if you dare put anything close to it or over top of it. That's a rant for another day though.
