2025 Curly-leaf Pondweed Treatment Maps

In 2024, the SRCLA had trouble securing DNR permits to do curly-leaf pondweed treatments in a timely fashion. This year, the DNR issued permits based on areas we permitted and inspected last year.

Please see these maps indicating the areas on Knaus, Horseshoe, Cedar Island (per the DNR, Cedar Island includes East and Koetter), Zumwalde, Krays, and Great Northern that will be treated in the coming weeks with 200 ppb of flumioxazin.

In addition, these maps of Long and Becker show the areas that will be mechanically harvested in the coming weeks.
