Water Levels Above Average From Stillwater, Minnesota To The Mississippi River
Water levels on the St. Croix from near Stillwater, Minnesota down to its confluence with the Mississippi River are above average for this time of year. Water levels elsewhere on the St. Croix and Namekagon are near normal summer conditions.
The St. Croix and Namekagon Rivers are always flowing and they are in a constantly shifting, dynamic state. Changing water levels and moving sand drive the change. The land that adjoins the rivers is also dynamic. Weather and climate change, geologic processes, fire, and human-caused factors such as air and water pollution are only a few of the agents of change that have helped to create the Riverway that we know today. The park provides a "living laboratory" that helps us better understand how these environmental factors have shaped park landscapes and ecosystems. Park staff are monitoring changes in environmental factors to alert managers to threats to the resources, hopefully, in time to prevent log term damage to the resources.

Before the invention of refrigerators, people harvested ice from rivers and lakes in the winter and stored the ice, covered in sawdust, in buildings. An ice house, storing ice from the river, once stood near the site of the park headquarters for St. Croix NSR, in St. Croix Falls, Wisconsin.
