Lethal Doses of Liquid Potash Will Be Used To Combat Zebra Mussels
Once the winter ice recedes on Lake Winnipeg, a silk curtain will be lowered to the lake floor to seal off four infested harbors. Liquid potash will then be pumped into the water until it reaches a lethal concentration for the zebra mussels and clogs their gills.
The technique has been tried in a closed quarry, but this is believed to be the first time liquid potash has been used in open water. Scientists who study the mussels say Manitoba presents a "golden opportunity" to find a way to prevent their proliferation in waterways around the world.
The invasive species are in their early stages of invasion in Manitoba and officials are hopeful the potash will eradicate the zebra mussels.
