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.

This will help restore the St. Croix to a level closer to what existed in the 1940's. more...

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.

Did You Know?
The Old Man of the Dalles is one of the many features visitors can see looking at the rocks in the Dalles, or rocky gorge, of the St. Croix River. A great way to view these rocky features, as well as St. Croix NSR, is from the water in a boat or a canoe.
