Destructive plant spreading in Geneva Lake lagoon

WALWORTH COUNTY, Wis. (CBS 58) -- A destructive plant discovered in a Geneva Lake lagoon is spreading. It's been nicknamed the "lake killer."

Starry Stonewart was discovered in two other locations in the lake. The plant could have a harmful impact on the ecosystem and interfere with boating.

The cost to remove the plant from the lagoon is $300,000.

"Eradication of this species in any lake has never been successful," said Ted Peters. "Now that it's out in the lake, I don't think we can eradicate this species. And I don't think it's appropriate to spend that kind of money trying to eradicate it."

The Geneva Lake Environmental Agency will discuss a plan of action Thursday night at a board of directors meeting.
