Missouri River near Omaha, NE - one year after flooding

In the spring and summer of 2011, the Missouri River experienced extreme flooding. Triggered by record snowfall in the Rocky Mountains of Montana and Wyoming, along with near-record spring rainfall in central and eastern Montana, reservoir levels approached dangerously high levels along the Missouri River in Montana and the Dakotas. To manage reservoir levels, a record amount of water was released to prevent overtopping of dams, which then contributed to flooding downstream. 

These Landsat images show the Omaha, Nebraska, area during the flooding in June 2011, and again recently on June 8, 2012. During the flooding, two major interstate highways, I-29 and I-680, were flooded, resulting in disrupted traffic patterns and damage to the roadways. Warm, dry weather has allowed the river to return to its banks, while cleanup continues on the highways and areas along the entire Missouri River. 

The 40 years of images in the Landsat archive is useful for context of widespread events, such as the 2011 Missouri River flooding, and aids in future planning and improvements for future potential catastrophic events.
