Starry Stonewort - A Real Threat to Clearwater Lake


Starry Stonewort is a real threat to Clearwater Lake.  The two closest lakes that are infected with it are Lake Sylvia and Lake Koronis.  In a matter of one year, it has virtually taken over Lake Koronis with no real treatment option.  It's important we all let other people know about it. 

Below are a few pictures from Lake Koronis that show the real damage it can cause. These pictures were taken at the end of August.  You are not able to drive a boat through it, you can't swim in it, you can't fish in it, it smothers spawning beds, and fish can't swim through it .  It is a lake killer and it is unlike Eurasian Milfoil in that it cannot be killed with chemicals.  The lake shore is being totally covered with this and it grows in depths of water up to 19 feet.  

Unfortunately, the DNR has not restricted access to these infected lakes and they have approved fishing tournaments on Lake Koronis.

 
 
 
 
 
 

Today the infestation is lake-wide. Using a mechanical harvester, the Lake Koronis Association has removed over 286 thousand pounds of starry stonewort from a four acre test plot. Residents are reporting infestations so thick they have trouble getting boats off boat lifts and into the lake, they have to paddle out past the infestation to motor up. Fishing off the dock or swimming from shore is impossible.

Starry stonewort threatens property values and tax base. Koronis resident Roland Ebert has seen a potential impact on home sales on Koronis. “Prospective buyers walk out on the dock and leave.” Said Ebert, “That’s why people buy a lake property, to enjoy swimming, boating, fishing and you can’t do that here. There’s no access."
