Is it something to do with more bottom sediment in Winni that gets churned up?

The particulates in the lake water limit the visibility. This is due to sediment runoff and the general muckiness of much of the bottom. And, of course, the warmer water brings algae formation. The ocean bottoms where I've dived are mostly sand and, the deeper, the cleaner, generally speaking. There's probably even more variables than that but I think that's the major ones.
