What's Up with Water Levels??
The Great Lakes are home to 20 percent of the world’s surface fresh water. But only about one percent of that water is replenished each year. The other ninety-nine percent is there because the glaciers melted and filled the deep scars on the earth’s surface.
Water levels are the result of a variety of processes -- rainfall, evaporation, historic dredging, erosion, ice cover, diversions, managed regulation, power generation and other factors. All interact in a complex and chaotic dance. And climate change is altering that dance – instead of a regal Viennese waltz the Great Lakes are now moshing in the pit at a rock concert.
The coming decades hold a promise: “nothing in their water levels past is a predictor of what will happen in the future.”
