I don't love the taste of Puget Sound. I know some of my fellow swimmers do. But the salt bothers me. Lake Washington, doesn't have the salt taste, but it isn't really a clean taste either. It is always a bit "green" like there is something growing. Which there is.
The best tasting lake I've swum in recently is Crescent Lake in Olympic National Park. The water had no taste at all. It was amazing. So clean! The color was remarkable too, blue, and clear deep enough to trigger my fear of heights as I came close to shore and could see the bottom again.
So although I don't try to drink the water (though I often get a face-full on a windy day) I am aware of the taste of what I swim in. Just one more reason to avoid polluting our waterways!
