Monitoring efforts continue for two invasive plant species | WXOW News 19

Monitoring efforts are continuing at both the US Fish and Wildlife Service and the Upper Mississippi River National Fish and Wildlife Refuge to help curb two invasive species. The water hyacinth and water lettuce were discovered in the Upper Mississippi on the shores of Lake Onalaska in October of this year. These two invasive species grow very rapidly and if left unchecked can end up taking over large areas in only one growing season, potentially causing damage to the ecosystem.


Alma derailment update | LaCrosse Tribune

ALMA, Wis. — There are no signs of damage to fish and aquatic life almost six weeks after a freight train carrying ethanol derailed in the Mississippi River backwaters near Alma.

BNSF spokeswoman Amy McBeth said Thursday that in consultation with the Wisconsin Department of Natural Resources and the U.S. Environmental Protection Agency, the railway has collected hundreds of surface water and sediment samples near site of the Nov. 7 derailment.

BNSF has also completed a survey of mussels and fish in the area. Sediment samples have been tested for toxicity at the Wisconsin State Laboratory of Hygiene in Madison.
