The Great Flood of Pueblo struck on June 3, 1921. It caused over $20 million in damages, destroyed entire neighborhoods, and to this day the full death toll is still unknown. This flood is considered one of the most devastating natural disasters in local history, it left a major mark on local culture and memories which endures to today.

To commemorate the centennial of this tragedy, El Pueblo History Museum documents the resilience of the Pueblo community in the face of natural disaster through a new exhibit open through October 2021. High Water Marks documents the history of water control in Pueblo County, the destruction of the Great Flood, and the strength and resilience of a community that not only recovered and rebuilt, but thrived.
