"Zebra Mussels Have Reached Texas"

"LAKE TEXOMA -- In a cove on this massive lake on the Texas-Oklahoma border, it doesn't take long to find zebra mussels.

Just a few feet from shore, a large rock is covered with them. A quick scan of the shoreline turns up many more.

This invasive species, an import from Eastern Europe, has long been spreading across the United States. The Great Lakes have been dealing with it for years, and now it has reached Texas.

So far, it has been found only in Lake Texoma and Sister Grove Creek, a tributary that the North Texas Municipal Water District uses to send water from Texoma downstream to Lake Lavon."
