The Lake was a little higher last year, is quite obviously higher than that this year.
The reason lake levels are higher is because a couple of years ago the effect of global warming made the ocean levels rise thus reducing lake levels.
But recently the great efforts to curb global warming by China, India, and other up and coming industrialized nations, has caused ocean levels to fall thus making lake levels rise.
Snowfall levels MAY reflect snowfall amounts. But I haven’t seen any real scientific studies chronicling that. I do know that snowfall levels effecting lake levels is crazy talk.
