is the second smallest of the five Great Lakes and shallowest. It can completely freeze over during winter. Once frozen, lake-effect snow over land to the east and south of Lake Erie is temporarily alleviated. This does not end the possibility of a damaging winter storm. The Great Lakes Blizzard of 1977 that struck metropolitan Buffalo was a direct result of powder snow blown by high winds off Lake Erie, which had frozen earlier than normal. There was, for the region, no significant snowfall during the duration of the blizzard. The southern and southeastern sides of the Great Salt Lake in Utah receive significant lake-effect snow. Since the Great Salt Lake never freezes, the lake effect can influence the weather along the Wasatch Front year-round. The lake effect largely contributes to the 55–80 inches (140–203 cm) annual snowfall amounts recorded south and east of the lake, and an average snowfall reaching 500 inches (13 m) in the Wasatch Range. The snow, which is often very light and dry because of the semiarid climate, is referred to as the "Greatest Snow on Earth" in the mountains. Lake-effect snow contributes to roughly six to eight snowfalls per year in Salt Lake City, with about 10% of the city's precipitation being contributed by the phenomenon."Lake has great impacts on storm, weather"
