In the central part of the United States, the Mississippi River runs deep through the country. To support such a massive river and life source, the Mississippi River needs hardy tributaries that feed it. Enter the St. Croix River: a long, winding body of water that stretches between two states and feeds the muddy Mississippi with clear, great water.
Learn more about the St. Croix River including how long it is, its ecology, what you can do for recreation on it, and how it compares to other tributaries of the Mississippi.
How Long is the St. Croix River?
The St. Croix River is approximately 169 miles long. Starting in the Upper St. Croix Lake in Wisconsin , the vast majority of the St. Croix River’s length creates the border between Minnesota and Wisconsin — which is just over 160 miles long.
As for depth, the range of the river’s depth oscillates between 70 to 100 feet depending on location.
