What's New
Written off as doomed, native mussels survive zebra mussel invasion
The Voice (10/9)
In the Great Lakes, invasive mussel species came close to wiping out native mussels, but significant remnant populations of native mussels have been discovered in the last 15 years and appear to be thriving.

DNR seeks federal approval to use potash on Christmas Lake to kill zebra mussels
Star Tribune (9/25)
If federal and state officials give the OK, Christmas Lake will be the first in Minnesota to use potash to kill off zebra mussels.

Minnesota lake first in nation to use new product to kill zebra mussels
Star Tribune (9/9)
A small Minnesota lake is on the forefront of the national effort to kill off the zebra mussels that threaten lakes and rivers around the country.

Salmon numbers dip in Lake Michigan
The Columbus Dispatch (8/17)
A precarious food chain might be the source of the low salmon problems in Lake Michigan.

Lake Erie: Is it time to worry again about its health?
Erie Time-News (8/12)
Lake Erie is the shallowest and warmest of the Great Lakes, making biological conditions more conducive for algae growth, and making the lake more susceptible to effects of climate change. And invasive species are a persistent threat.

The creatures you're most likely to encounter in the Great Lakes
Michigan Radio (8/11)
Ever wonder what you can find below the surface of our Great Lakes? A researcher tells us.

Overview
PhragmitesZebra mussels (Dreissena polymorpha) are small, fingernail-sized mussels native to the Caspian Sea region of Asia. Considered one of most damaging of the invasive species introduced to this country, zebra mussels were transported to the Great Lakes in ballast water from a transoceanic vessel. Since that time, they have spread rapidly to all of the Great Lakes and waterways in many states, as well as Ontario and Quebec, and to southeast and western portions of the United States.

One of the zebra mussel's most defining characteristics is its tendency to colonize hard substrates and surfaces (e.g., rocky bottoms and water intake structures) in high densities, with as many as tens of thousands living in a square yard.

Zebra mussels have had deleterious effects on local ecosystems. They reduce the amount of phytoplankton available for other organisms and increase water clarity, causing changes to the ecological structure of the lake community. In addition, zebra mussels accumulate contaminants within their tissues to levels greater than concentrations in the water column, increasing the exposure of wildlife to contaminants. Zebra mussel infestations also threaten native mussel populations by attaching to the native species and essentially smothering them.

Zebra mussels have caused a great deal of economic damage by clogging intake pipes of water treatment and power plants as well as boat engine cooling systems. Unfortunately, solutions to these problems are few and not highly effective, resulting in high costs for cleaning and control measures.

Glen Canyon National Recreation Area Expanded Zebra Mussel Action Plan (2007)
National Park Service, U.S. Department of the Interior, Glen Canyon National Recreation Area, Arizona and Utah
An Action Plan to prevent the spread of zebra mussels in Lake Powell and the upper Colorado River. The Zebra Mussel Prevention Program was further expanded in May 2008, at which time both Lake Powell and the upper Colorado River were believed to still be free of the mussels.
