Boyer Chute National Wildlife Refuge, created in 1992, is a National Wildlife Refuge (NWR) located along the banks of the Missouri River in the U.S. state of Nebraska.
 The 4040 acre refuge preserves an area that had been cultivated and neglected before the early 1990s.
 Channelization projects along the Missouri River to improve flood control and navigation resulted in the closing off a side branch of the river, known since the early 19th century as Boyer Chute.
 Between 1820 and 1937 the Missouri River had migrated 3 mi eastward and the area of the chute had originally been on the east bank of the river; today, the chute is west of the main channel of the Missouri.
 In 1937, the Army Corps of Engineers began to rechannel portions of the Missouri River, cutting off the chute to flowing water.
 Overgrowth and cultivation took over the lands now preserved in the refuge.
 Restoration of the area commenced in 1993; this included planting 9,100 native plants and trees and restoring the inflow to the chute from the main channel of the Missouri River.

Cow Creek is a tributary of the Missouri River, approximately 35 mi long, in north central Montana in the United States.
 Cow Creek rises in the southern foothills of the Bear Paw Mountains in western Blaine County and flows east and then south, joining the Missouri approximately 25 mi northeast of Winifred, Montana—or 22 mi upstream from the Fred Robinson Bridge.
 Cow Creek flows down to the Missouri in a canyon that passes through the Missouri Breaks, which are severely eroded badlands that extend out on either side from the Missouri River.
 The floor of Cow Creek canyon provided a pathway of travel from the Montana plains north of the river, down to the Missouri – at the mouth of Cow Creek, Cow Island made fording the Missouri easier – a steep but short trail on the south bank of the Missouri opposite Cow Creek completed this route which led from the northern Montana plains to the central and southern Montana plains.
 This pathway was used by migrating buffalo/bison and nomadic American Natives for centuries.
 During the steamboat era on the Missouri River, when low water prevented riverboats getting up to Fort Benton, the mouth of Cow Creek became a river landing and freighting depot, and it was the start of the Cow Island Trail by which freight was moved on to Fort Benton by going north up Cow Creek and then west.
 In 1877 the Nez Perce Indian Tribe, fleeing to Canada, had several skirmishes along Cow Creek including the "Battle of Cow Island", and several days later at a camp on Cow Creek the Nez Perce, thinking themselves now beyond the reach of the U.S. Army, made the fateful decision to slow down, rather than push on for the Canada–US border.
 Today, modern highways have by passed Cow Creek, and the buffalo and the nomadic Indian are gone.
 Cow Creek is dormant, in one of the most remote spots of the isolated regions of the vast area known as the Montana Missouri Breaks.

The 2011 Missouri River floods was a flooding event on the Missouri River in the United States.
 The flooding was triggered by record snowfall in the Rocky Mountains of Montana and Wyoming along with near-record spring rainfall in central and eastern Montana.
 All six major dams along the Missouri River released record amounts of water to prevent overflow which led to flooding threatening several towns and cities along the river from Montana to Missouri; in particular Bismarck, North Dakota; Pierre, South Dakota; Dakota Dunes, South Dakota; South Sioux City, Nebraska, Sioux City, Iowa; Omaha, Nebraska; Council Bluffs, Iowa; Kansas City, Missouri; Jefferson City, Missouri, as well as putting many smaller towns at risk.
 According to the National Weather Service, in the second half of the month of May 2011, almost a year's worth of rain fell over the upper Missouri River basin.
 Extremely heavy rainfall in conjunction with an estimated 212 percent of normal snowpack in the Rocky Mountains contributed to this flooding event.
