Potash injected in Christmas Lake to fight zebra mussels

In what is hoped to be the final blow to zebra mussels in Christmas Lake, on Dec. 19 a contractor working with the Minnesota Department of Natural Resources (DNR) injected 1,000 pounds of potash (potassium chloride) into an enclosed area of the lake at the public boat launch where the mussels were discovered by the MCWD in August. 

The DNR has worked with the MCWD and City of Shorewood on a multi-prong response since the infestation was discovered. The lake has also been treated with Zequanox and a copper-based product. 

If the potash application succeeds as a follow-up to the earlier treatments, it will be the first time zebra mussels have been eradicated from a Minnesota lake.  Learn more here
