Protecting Freshwater Starts With Understanding Watersheds
MN Water Shed covers watershed science, freshwater conservation, and what it all means for the water coming out of your tap. Practical information for homeowners, hikers, and anyone who cares about local water quality.
Why Watersheds Matter for Your Water
Every rain that falls on your neighborhood drains somewhere. Where it goes, what it picks up along the way, and how it gets treated before reaching your tap is what watershed health is actually about. We cover all of it in plain language.
What We Cover
Four topic areas covering how watersheds work, what threatens water quality, and what you can do about it.
Watershed Basics
How land, rainfall, wetlands, streams, and lakes connect inside a drainage area.
Water Quality
Plain-English coverage of runoff, sediment, nutrients, bacteria, PFAS, and drinking water concerns.
Wetlands & Habitat
Why wetlands, riparian buffers, and native vegetation matter for clean water and flood control.
Conservation Planning
Practical ways communities, homeowners, and landowners can reduce runoff and protect freshwater.

Residential Water Quality Resources
Understanding watershed health is only part of the picture. What enters the watershed eventually reaches residential water supplies. These resources help homeowners evaluate and address water quality at the tap.
- Quality Water Lab – Independent testing data on how home water filtration systems perform against common contaminants including PFAS, chlorine byproducts, lead, and heavy metals.
- EPA Drinking Water Resources – The U.S. Environmental Protection Agency’s drinking water portal covering regulations, contaminant standards, and local water quality information.
