Water Quality

The St. Croix River is known as one of the cleanest rivers in the Midwest. Yet all is not well, even with the St. Croix. In 2006 Wisconsin and Minnesota signed an agreement to work toward a 20% reduction in phosphorus loading in the St. Croix River Basin. This will help restore the St. Croix to a level closer to what existed in the 1940's. more...

A Habitat Classification Report looks at the rivers and divides them into segments.  This may help you better understand the rivers in regard to water quality.  more...  This document also has appendices.

 

The St. Croix's water quality is a major factor in the St. Croix having a mostly intact mussel population. This includes 40 species, two of which are on the endangered species list. Learn more about mussels.

A green dragonfly emerges from its old skin, seen below.

Did You Know?
Dragonflies spend most of their life living in the water. Eventually they climb out of the water and grab onto something. Here they will emerge from their old skin like a butterfly emerges from its cocoon and fly away.
