In the "Concise Dictionary of European proverbs" I found the English versions of this saying,
http://books.google.com/books?id=HJ_...nes%22&f=false
A good winter brings a good summer.
A snow year, a good year.
A snow year, a rich year.
A year of snow, a year of plenty.
Under water famine, under snow bread.
I like one of the French versions,
Anée neigeuse, anée frutueuse.
