Zebra mussels invade all Great Lakes within a decade

Zebra mussels, an invasive species from Eurasia, spread across all five Great Lakes within a decade of their 1988 arrival via ballast water. Now, Texas officials have declared Lake Meredith fully infested, marking the state's 35th such lake. The mussels damage ecosystems, infrastructure, and recreation, and their presence in the Panhandle raises fears of westward spread. Prevention relies on cleaning boats and equipment.
