You hit the nail of the head - it's the oxygen levels that causes winter kill.
What is the cause of low oxygen - Snow On Top of the Ice Filters out the sun light that the reservior or lake needs to genterate oxygen from plants and algea. The shallow lakes have less stored oxygen so they tend to be killed if large amounts of snow stay on the ice for long periods.
This is what my Dad has told me about the lakes in South Dakota - where wintertime and iced over lakes are in abundence.
