As Great Lakes plummet, towns try to save harbors
Lowering water levels caused by drought and rising temperatures
Water levels on the Great Lakes are falling to worrisome lows because of drought and rising temperatures, causing problems in the shipping industry and in small communities with recreational harbors.
The water is at near-record lows on lakes Michigan and Huron, while Erie, Ontario and Superior are below their historical averages. Cargo freighters have been forced to lighten loads, marinas have become too shallow for pleasure boats and weeds are sprouting on exposed bottom lands, chasing away swimmers and sunbathers.
Congress used to provide money to dredge channels and repair other infrastructure for small communities. But those special appropriations, called "earmarks," have fallen out of favor.
That leaves small towns scrambling to find ways to attract recreational traffic such as fishing charters, sailing yachts and motorboats.
