Lake Lethal was a lake on Sergyar south of Mount Stewart. A deep lake in an interesting geologic environment, it had a carbon dioxide inversion layer. Thus, while perhaps appearing inviting, it was likely to abruptly release its load of gas killing anything nearby.
Cordelia Vorkosigan chose the name to discourage settlers from setting up homes near it.
