Please see below for an important update regarding 2nd Lake in Trempealeau. If you have any additional questions regarding this information, please reach out directly to the Wisconsin DNR.
**Important Lake Protection Update**
Over the past several weeks, the Wisconsin DNR has identified and removed a highly invasive aquatic plant from 2nd Lake in Trempealeau. It is believed that this plant may have been introduced into the lake through the improper disposal of aquarium or water garden materials. If established, this invasive species could cause significant harm to our lake ecosystem and native aquatic habitats.
Please help protect our waterways by never releasing aquarium plants, animals, or water garden materials into lakes, rivers, or streams. If you see this plant or suspect the presence of an invasive aquatic species, please contact the Wisconsin DNR immediately. Together, we can help keep the Trempealeau Lakes healthy for future generations!
