Zebra Mussels Invade Lake Lewisville, Continue Inevitable March Into Dallas' Water Supply

Thirty years ago, no one in the U.S. knew what the hell a zebra mussel was. Five years back, the stories of the damage they can wreak on municipal water systems and aquatic ecosystems were still a fairy tale for Texans. Fifteen months ago, wildlife officials remained confident that the threat was confined to Lake Texoma.

The mussels made their debut in the Trinity River basin last year, showing up at Lake Ray Roberts north of Denton. State officials doubled down on their effort to slow their spread with their wash-your-damn-boat public education campaign, but you didn't have to be a biologist to see where this saga was heading, which is the Gulf of Mexico.

The bivalves have taken yet another step in that direction. The Texas Parks & Wildlife Department announced today that a U.S. Geological Survey biologist recently discovered a juvenile zebra mussel in Lake Lewisville. It probably got there by boat.

This is bad news, not only because Dallas gets water from Lake Lewisville -- zebra mussels don't affect water quality, city officials say, but they are a pain in the ass to clean off water intakes and other equipment -- but also because people like to boat on the reservoir, meaning that the likelihood of someone forgetting to drain and rinse their craft before taking it to another lake is high. Unavoidable even.

Parks & Wildlife will no doubt urge us to keep fighting the good fight, but spirits inevitably flag when facing an invincible foe. Maybe it's time to give up and embrace our new aquatic overlords.

Once the mussels get to party cove, they'll kill themselves after the horrors they see.

Steam a bucket of 'em and serve with melted dipping butter, lightly salted.

or grind them up and feed them to the livestock.

If its inevitable, there's no need to get upset Carp, Zebra Mussels and Mexicans, all part of the inevitable New Texas.

We spotted them in Ray Roberts at least four years ago. Took pictures to confirm it - they were ALL over a rope our anchor nabbed. If biologists are so far behind, imagine how many more lake and pipes zebra mussels have taken over. Scary shit.

After pulling the boat out of the water isn't the first thing you do is pull the plug?

We just need to import some lion mussels that enjoy killing and eating zebra mussels.

If we can get Mexicans to figure out a way to make carp & zebra mussel tacos, it'll work itself out.

@RTGolden1 Unfortunately, even they are unlikely to keep the zebra mussels in check.  They just breed too prolifically.

We have a number of native species that feast on them.  Catfish eat them a lot.  Freshwater Drum eat them in large numbers, and although they contribute to a high mortality rate among zebra mussels, they don't actually do much to reduce their numbers.
