The Riley Purgatory Bluff Creek Watershed District has stopped the spread of Eurasian watermilfoil in Staring Lake thanks to efforts this month.

After the invasive aquatic plant was spotted in the 155-acre lake in Eden Prairie for the first time, Watershed District staff, volunteers and experts waded into the lake and hand-pulled the plants, which were concentrated around the public boat launch and a fishing pier. It was followed by an herbicide treatment the following week. The Watershed District will continue to monitor the lake to see if any plants return.

Eurasian milfoil has infested other west metro waterways such as Lake Minnetonka and Minnehaha Creek, among more than 270 infested lakes and rivers in Minnesota, according to the state Department of Natural Resources.

The event will take place at The Adopt-A-Pet-Shop and will include teen author Justin Anderson, a Wayzata High School freshman, signing copies of his book, "Saving Stripes: A Kitty's Story" from 11 a.m. to 1 p.m.

All proceeds from the $10 book will benefit S.O.S. Rescue Relief inc., which runs the pet shop.
