Missouri River

The Missouri River’s the longest river in North America. It starts in Western Montana and ends North of St. Louis, Missouri. Most people think that the Missouri River was made over 30 million years ago, but because its changed its stream over time, the current course of estimation is at 115, 000 years old. The first human life emerged in the valley of the Missouri river past 12 thousand years ago. The banks of the Missouri River were settled on by more than 10 different tribes of Native Americans

The fragility of river biome ecosystems are increasing more and more with each passing year. Development of man-made, hydraulic obstructions and pollution are two of the biggest factors putting the Missouri River at risk. Less than 70% of the planet’s longest 177 rivers are without man-made structures, such as dams. The number will only continue to increase as global populations grow and untapped rivers are targeted. Structures built on rivers negatively affect plants, animals, and especially humans

and environmental contaminants may have also played a role in the pallid sturgeon's decline. The resultant changes to the Missouri River in the upper Great Plains from channelization prevent upstream migration. The reduced water flow rates and sediment loads have brought an end to the seasonal flooding of the flood plains in the region.

There is an extreme amount of pollution in the Missouri River. Lots of rivers are being polluted, but one of the worst is the Missouri River. For example “According to the EPA, in 2007 the amount of pollution dumped into the Missouri River within the boundaries of our state totaled pounds.” (Top Ten Frightening Facts About The Missouri River, 1). The amount of pollution that has been deposited into the river is terrifying. Even companies that we trust and are a part of our everyday life like Tyson

The Missouri River can be a wonderful yet terrible place. So much joy can be experienced from being on the river, but at the same time, so much destruction can happen. I have had both wonderful and terrible experiences on this river. It was another beautiful day on the Missouri River. The air was crisp. A slight breeze drifted over the ice covered river. The sun was illuminating onto the ice making a bright white light. You could not have asked for a better day of ice fishing. Luckily for us, we

Before the expeditions of todays well known Lewis and Clark, the entire western end of the United States was uncharted territory consisting of new peoples and surroundings waiting to be discovered. A member of this team included John Colter , who is an unknown person to most historians. Colter was an important piece of this group, and though he did not stay with Lewis and Clark during the entirety of two years, from May 1804 to September 1806, he was an essential component of their travels. While

The acquired Louisiana territory doubled the size of America and allowed the boundaries of the country to be extended. This acquisition of land became to be known as the Louisiana Purchase. However, the new and unknown territory had to be explored in order to obtain an accurate sense of the strange land and what resources it had to offer. Jefferson was in need of someone brave enough who would take on the challenge and achieve success. The role best fit the appointed soldier, politician, and public

11-20-2014 Romero DUAL Within the time period of 1801- 1809 Thomas Jefferson was President and participated in the Louisiana Purchase. America bought 820,000 square miles from France. (All land that stretched from the Mississippi river, in total 15 states were bought from the purchase.) With this amount of un-known land, Jefferson called for an exploration and hired Meriwether Lewis, Jefferson’s secretary, due to his penmanship and frontiersman skills. Lewis grew up in Virginia and

from the dam construction. Bed aggradations on upstream of dams are seen as a result of such disturbance. Sediment particles in the river are in form of sand, silt, gravel and even larger boulders. Water flowing in the river, scours its bed and banks, detaching these sediment panicles from the surface and carries them to the downstream. If a dam is constructed on this river, the velocity of the flowing water is reduced due to obstruction, thereby helping the sediment panicles to settle down in the reservoir

on unstable regions of the world for our oil consumption. This oil would come from North Dakota, which says to contain undiscovered 7.4 billion barrels of crude oil. This pipeline would build underground crossing about 200 wetlands, including Missouri River, and 4 states of dry lands; the route will be starting from North Dakota to South Dakota and Iowa, then into Illinois. In Illinois it will be connected to other pipeline companies to transfer this oil all the way to Gulf of Mexico. And since it
