Beth Knutson is an expert when it comes to Minnesota and the watersheds that helps keep our water supply safe and sound.

In fact, she developed a tool the DNR uses to test the health of our watersheds, and will show you how to use it at an upcoming workshop.

If you're a land owner, if you like to go outside and enjoy Minnesota's lakes and rivers, or if you just want to make sure your descendants can still get a crystal clear glass of fresh, pure water to drink many years from now, listen to the conversation we had earlier this morning on WJON.

(And if you don't have an inkling what a watershed is and does for you every day, this interview is a must-hear).
