Mussel-headed news: Do not panic

Mussel control: A swarm of zebra mussels have attached themselves to this larger regular mussel. The invasive species has been spreading across the U.S. and have now shown up in three Ramsey County lakes, part of many east-metro area drinking water supplies. But their pressence doesn't impact the drinkability of the water. (Photo courtesy of the U.S. Fish and Wildlife Service)

I would have expected this from television news, but this was actually a breaking news story on the Star Tribune website today: zebra mussels have been found in three local lakes that provide water to municipal drinking water systems to east metro cities. A little further into the piece, it does remind us that zebra mussels do not affect the quality of drinking water. The only significant public health issue, I guess, is that the mussels can congregate around and clog up intake pipes for the water systems.

Here’s some other breaking news, from me, about our water supplies: geese poop in them, huge carp (and assorted other fish) die in them, and lots of other natural but nasty things occur there as well. That’s why we have water treatment plants and add chemicals that help purify our water.

What’s distressing is that the spread of zebra mussels is now jumping from the Mississippi River into other local bodies of water where they have no natural predators to control their numbers. And the article barely addresses that issue.

There are no natural predators anywhere in the US for Zebra Mussels that is why they are a problem.
