It is with heavy heart that LILSA must announce the following passing of a dear friend and member of our group:

Steve Hoyda passed away on April 23/22. Our thoughts and prayers are with the Hoyda family during this time.  Steve was a staunch supporter of improving the quality water in the lakes of Lac Ste County. He represented the County on the LILSA Board of Directors since 2017. Steve was especially passionate on working with Alexis First Nation to deal with flowering in Lake Isle. We will miss his contributions to our Society.
