Montana's waters are an important part of the Montana way. But, we all need to do our part to keep them clean and healthy. Join a ranger to learn about aquatic invasive species, how they impact our ecosystems, and what you can do to prevent them. Test your knowledge and practice identifying aquatic invasive species. This is a two hour program, with games and activities for the whole family! The cost of this program is $4 per person, or $10 per family, and will be held at the Harry Horn Picnic Shelter from 12 pm to 2 pm.
