Mississippi River Futures: Managing a Vital Watershed for the Next 100 Years

Panel Speakers:

In 1926, the Mississippi River was declared effectively dead in the Twin Cities. In 1927, the Great Mississippi River Flood devastated the lower end of the basin. Both events reshaped our relationship with the Mississippi River and triggered a century of change for the communities, economies, ecosystems, and infrastructure connected to the River. This panel will look ahead and ask what the Mississippi River Basin should look like for the next century. Can we manage this multi-use river more dynamically as conditions change? What role can nature-based solutions play across the watershed? How can we strengthen collaboration and learning across sectors to emerge a more resilient approach to managing America’s most consequential river system?

Mississippi River Gorge in Minneapolis-St. Paul: Impact of Alterations and Plans for Restoration

The Mississippi River flows through a limestone and sandstone confined valley or gorge cutting through the Twin Cities of Minneapolis and St. Paul. For centuries the gorge has been a place of reverence, transport, sustenance, and transformation. In this special session, we’ve gathered a broad range of presenters to share history, perspectives, technical understanding, and possible futures for the Mississippi River gorge. We’ll leave time for question and discussion between attendees and presenters.
