As funny an image as it makes for jeets using Canada's lakes as a toilet, it's not human shit, it's bird shit and farm runoff. Chestermere Lake isn't a real, natural lake, it's a giant, stagnant, man-mode ditch that's been repurposed as a "recreation area." It can't filter naturally because there's virtually no flow in or out, and when you do have flow, it's local rains that just flush shit in nearly as often as it flushes it out. I have no idea how it's ever safe and I would never actually step foot in it myself. I wouldn't even want to be downwind of it on a hot day.
It's possible to grant a body of water natural filtering capacity with cat-tails and aquatic vegetation and various crtitters, even if there is no outflow. Surface vegetation, like duckweed, are especially effective. I dunno what the lake in Chestermere is like though.
