Lake Superior drying up? Well, not exactly, but this trend is worrisome.
Lake Superior has dropped nearly a foot this year to its lowest late-autumn water level in eight decades, a startling decline that is raising worries about shipping, shorelines and fish populations.
Long-term lower levels on Lake Superior, as on any lake, would be a problem for shorelines, where vegetation might change and then be disrupted by a quick rise, and where people might be tempted to build new structures, Johnson said. She and others said that wetlands, like those along the south shore, would lose water, reducing habitat for wildlife and underwater organisms, and eliminating the water-filtration role that wetlands play.
