A group of LRIA members met with Olivia Nyffeler from the University of Minnesota last night to hear about her research study of Zebra Mussels in Lake Riley.  Josh Maxwell from the Watershed District, Lori Haak from the City of Eden Prairie, and a representative from the US Geological Survey joined her.  The research project is being funded by the USGS.  This will be Olivia’s Ph.D. project working under the guidance of Prof. Gretchen Hansen.
 
You may have noticed the buoys they put in the lake to monitor Zebra Mussels.  The buoys have a USGS logo on them.  They will be there for 2-3 months, and the plates are about 10-12 feet deep.
 
Chemical treatments won’t be done until late July or early August 2026.  The low dose copper treatments will not interfere with any enjoyment of the lake such as swimming and are not expected to have any adverse effects on fish.  
 
This is a follow up study to what was done in Lake Minnetonka.  Here is a short summary of that study.  https://maisrc.umn.edu/news/mnkta-copper
 
It might make sense for Olivia to speak at a future LRIA Annual Meeting to educate us on what she learns.

Hi LRIA members,


At our annual meeting, we discussed creating a Facebook page for the association that could allow LRIA members and residents/friends of Lake Riley to join and post pictures of fun activities on the lake and post other questions and concerns that may be helpful to share or ask the group through social media.

A private group has now been created. Feel free to search "Lake Riley Improvement Association" or click the link below and ask to join the group. Share this site with other Facebook users who love the lake and also may enjoy considering joining the association.

Take care and hope to see you on the lake soon as the weather warms up.

The MN DNR approved RPBCWD's application for chemical (herbicide) control of Curly-leaf Pondweed on Lake Riley. The herbicide treatment is scheduled for the week of May 5thwith treatment most likely occurring near the beginning of the week, weather permitting.
 
The herbicide applicator will post signage on shoreline that is within 150 feet of the application area. Attached is the treatment flyer which shows a map of the treatment areas.
 
Any updates or changes to the treatment timeframe will be posted on:
