The untamed Missouri River continues to alter the landscape of the Missouri River Basin, as shown in the Landsat satellite imagery above of the river near Decatur, NE, and Onawa, IA. Available evidence from the flood zone indicates that as new channels and deep cuts through the valley lowlands are likely being gouged, the rich farmland and countless human constructs are being destroyed or washed away in the months-long flood. In both images, vegetation is green.

Heavy rains and snowmelt have caused record flows in 2011 along the Missouri River and caused the river to remain above flood stage for months. These Landsat satellite images demonstrate the extent of the flooding in central Missouri. In both images, green represents vegetation, purple represents urban areas, and brown-red represents bare ground.

Normally the Missouri River meanders through Sioux City IA, and Omaha, NE; however, that hasn’t been true this year. The Landsat 7 images above show the extent of river flooding as upstream runoff from snowmelt and rainfall continues to surge through the area. Runoff into the Missouri River Basin above Sioux City during June was the highest single runoff month since the Army Corps of Engineers began keeping detailed records in 1898. The river narrows in the cities because of protective levees. In both images, vegetation is green.

The Las Conchas Fire, New Mexico's largest wildfire in recorded history, has burned over 135,000 acres to date. The fire began on June 26 when an aspen tree was blown down by strong winds, falling on power lines. In these Landsat images, vegetation is green, and dark red represents the burned area.

Started by lightning on April 30, the Honey Prairie Fire in southeastern Georgia, has burned over 291,000 acres in the Okefenokee National Wildlife Refuge. At this time, the refuge is closed and visitor activities have been suspended. Fire crews continue to control reburns and mop up hotspots. In these Landsat images, vegetation is green, and dark red represents the burned area.

Heavy rains in Canada caused historic flooding in Minot, North Dakota. The Landsat satellite images above reveal the extent of the flood. The Souris River, which flows through the middle of Minot, finally crested on June 26, but not before more than 4,000 homes and hundreds of businesses were flooded. About one-fourth of Minot's 40,000 residents evacuated the city. Residents expect a long recovery as the river slowly retreats.

The images are false-colored to allow ease of identification of various objects that will help firefighters and emergency managers. Burn scars are red in the images, with ongoing fire as bright red , vegetation is green, smoke is blue , and bare ground is tan-colored.

Landsat images show water collecting behind Gavins Point Dam near Yankton, South Dakota. On June 23, the U.S. Army Corps of Engineers increased the flow of the Missouri River through Gavins Point to 160,000 cubic feet per second. Heavy rain in the area triggered this latest release. The flow through the dam is expected to remain at this level through August. Downstream communities face flooding from the record high releases from Gavins Point and other upstream Missouri River reservoirs.
