What metaphors are used in Women in Love by D.H. Lawrence?

This is an annual event that was started years ago, under Mr. Crich's impetus. He invited the people to the manor, and entertained with music, food and boating. At the water party described in the novel, Gerald's younger sister Diana falls in the lake, and when a doctor's son dives in to save her, she clings to him and kills him, so that the lake has to be drained before their bodies are found. Swimming in this lake becomes a metaphor for ill omens.
