PBH,
Another factor that plays a role in winter kill is the release of hydrogen sulfide from lake sediments. When the oxygen bottoms out, H2S is released and the water becomes toxic as well as anoxic. It's that rotten egg smell you sometimes get at iceout. Pelican Lake is a low elevation water that is subject to winter kill because all that vegetation decays under the ice consuming the oxygen which leads to the release of hydrogen sulfide.
