Lake Coeur d’Alene Eurasian Milfoil Control Program Kicks Into Gear

In 2011, Aquatechnex biologists performed a number of water exchange studies on the lake, and worked with Barrier Curtain Technologies we developed in 1999 to isolate treatment areas in high water exchange sites. This improves herbicide efficacy dramatically

Aquatechnex biologists are embarking on a Eurasian Milfoil control program on the southern end of Lake Coeur d’Alene this week.  The $450,00.00 project involved monitoring and mapping Eurasian Milfoil and native aquatic plant communities in that portion of the lake and tributaries, treatment of extensive Eurasian Milfoil beds with a selective herbicide and using barrier curtains to contain the herbicide within treatment areas to reduce movement and flow, and post treatment evaluation.

Additional information during the treatments can be found on
