Columbia River Basin
Section 1: Introducing the Columbia River Basin
What do you get when you put together a flowing river, with a beautiful mountain, and a rolling valley? The result is the amazing Columbia River Basin. The Columbia River is the sculptor that carved the Interior Columbia River Basin. The Columbia River Basin is made up of many different environments, and contains many different organisms. Mountains, high plateaus, desert basins, river valleys, rolling uplands, and deep gorges woven together by the Columbia River and its tributaries make up the whole Columbia River Basin.
People have been drawn to the big and beautiful Columbia River Basin for thousands of years. During the last century, natural resource-based industries supported small, growing communities. Today, people still appreciate the basin's rural flavor and quality of life.
There are many beautiful places in this wonderful area of Oregon. In fact the whole basin was deemed a National Scenic Area. Besides the whole area there are two others natural areas that are very prominent. Among its many waterfalls Kalamath Falls is by far the most breathtaking. Not only can you enjoy the waterfall its self but also if you look hard enough you can see life happening all around you. If you travel up a lot higher you will see the natural trademark of the Pacific Northwest, Mt. Hood. With its 11,239 feet of beauty, what’s not to love? This amazing mountain is not only a natural area, but an area for recreation as well. From the river bellow to the mountains above the Columbia River Basin has a lot to offer.

... North America, steelheads are found in Pacific Ocean drainage from southern California through Alaska. In Oregon they are found throughout the Columbia River. The major factor causing steelhead population decline is freshwater habitat loss and degradation. This has resulted from three main factors: inadequate stream flows, blocked access to historic spawning and rearing areas due to dams, and human activities that discharge sediment and debris into waterways.

The purpose of this paper is to explain and highlight different aspects of the Powder River Basin to include paleogeography, stratigraphy, maturation history of organic material, vitrinite reflectance data, sulfur content, both historical and current production data, as well as the environmental impact in the basin.
Colorado River Hydrosphere A case study of * River management * People interfering in the hydrosphere * Balancing water from one area to another The Colorado river - basic facts It flows through southwest United States and northwestern Mexico. It is 2334 km (1450 miles long), the longest river west of the Rocky Mountains. Its source is west of the Rocky Mountains which is the watershed in northern Colorado, and, for the first 1600km (1000miles) of its course, passes through a series of deep gorges and canyons that were created by the eroding force of its current. The river flows in a generally southwestern direction across Colorado into south eastern Utah, where it is joined by its chief tributary, The Green River. After crossing the northern portion of Arizona, the Colorado flows west for 436 km (271 miles) through the majestic Grand Canyon.
When Meriwether Lewis and William Clark first explored Montana in the early 1800s, they were awestruck by the open plains and delighted by the wide range of animals that roamed the land. After reaching the Great Falls, which is on the Missouri River in what is now Montana (Av2 books). Lewis wrote in his journal that it was “the grandest sight” that he had “ever beheld.” Today much of the landscape the Lewis and Clark crossed remains unchanged. The dense forest, rugged mountains, and rushing rivers are still abundant with fish and other wildlife.
The world has been shaped by many events. Like a sculpture each piece was a result of an event that made it that way. The Snake River Canyon is no different, most of upper Utah and part southern Idaho show the scars of an event that rocked the landscape into what it is today. When researching and digging in the region you can find remnants of an old marine environment, from sediment deposits to river terraces hundreds of feet high. It’s confusing to think of the area as a giant lake with sandy beaches and powerful waves, but the overflow of this huge lake is what created most of the landscape you can see today. The great Bonneville flood was the world second largest flood, emptying over 32,000 square miles of lake volume. (Utah Geological Society) The flood that the this overfill caused carved through many areas and created the beautiful valley that can be seen there. However, this didn’t just happen over night. The pre-flood history, flood event, specific flood deposits all played an important role in shaping this large Geological marvel. Understanding what happened back then can give us a good glimpse into better understanding the region today, which can lead to better predicting and preserving for the future.

The region surrounding the Columbia River is one of the metaphors that can be found for the term “Buffalo Commons”. In this region a serious debate is taking place over the removal of some of the dams along the river. By shifting the economic dependency on the river to alternative sources there is a hope that the Native Salmon will be able to re populate and flourish in an area were they had once been plentiful (Ka-bye).
To tell how healthy a body of water is, you would need to measure the amount of dissolved oxygen (DO) in the water. Water is only able to dissolve a certain amount of oxygen to be classified as healthy. And once, the maximum amount of oxygen from the atmosphere that can dissolve in water, which is about 9.8 mg/l, is reached , no more oxygen will dissolve. This shows that water needs to maintain a certain amount of dissolved oxygen, typically 4-5 mg/l, for it to be classified as healthy and to support aquatic animals. If the dissolved oxygen levels drop below 5.0 mg/l, the aquatic life will be put under stress. The amount of dissolved oxygen in the water is affected by several physical and biological (natural) factors.
The Ohio River Basin covers the area about 203.940 miles, which is located in northeast of the United States surrounding the easternmost regions of the Mississippi Basin. The mainstream of the basin, the Ohio River itself, winds its way through 6 states or commonwealths around: Pennsylvania, Ohio, West Virginia, Kentucky, Indiana and Illinois. The basin consists of one mainstream, which serves as the largest tributary of the Mississippi river, and its various tributaries, among which the Allegany and Monongahela tributaries serves as the source water of the Ohio river mainstream, where the Ohio River begins at the confluence of these two tributaries. The Ohio River basin cover across 15 states that supports beyond 27 million people, equaling to 10% of the population in the United States, with drinking water, jobs and various kinds of recreational opportunities.

a Watershed is an area of land where all of the water that is under it, or drains off of it collects into the same place. Most of the watersheds in Idaho are part of the Columbia River Basin Watershed, which drains into the Pacific Ocean big cities use a lot of water and when they use too much the place they get the water from might run out.
On Saturday, April 25th, the class went on a field trip to different locations around the Blacksburg-Christiansburg area to view different land formations typical of the Virginia area. We visited a total of eight sites to include the Kentland Farms, VT airport, Blacksburg Golf Course, and several road side areas. The weather conditions that day were cloudy with intermittent showers making the ground very wet and reducing visibility across large landscapes for the majority of the day. This paper will serve a summary of each stop made and will tie all of the observations together into big picture concepts for the New River basin.
The Mississippi river roughly 2,340 miles in length has turned into one of the most active waterways that we know today. According to Cornelia (2006), the Mississippi river once performed like a conveyor belt which transported nutrient-rich sediment downstream and deposited it along the barrier islands and wetlands before the flow of the river was controlled. The U.S Army Corps of Engineers have built dams and levees throughout the river since the 1820s to help protect against flooding. Consequently, this caused the barrier islands as well as the wetlands to disappear due to the lack of sediment that was being distributed to the location. Scientists have argued back and forth weather to allow the Mississippi river to change its course or should

Unlike most basins, the headwaters of the Klamath River are in the high desert of the Great Basin in eastern Oregon and travel south through the temperate rainforests of the Pacific Coast Mountain Range in north Central California, before finally draining into the Pacific Ocean in coastal California. The river basin spans a total of 5,700 square miles in an hourglass formation and includes parts of three counties in Oregon and five counties in California (Bureau of Reclamation 2016). The communities living in the “upside down” basin are as diverse as its climatic ranges in their cultures and livelihoods, but are bound by their reliance on the same sources of water.
There is something transcendent about it. The first time you indulge in its beautifully blue water and breathtaking natural surroundings, you are instantly mesmerized. To the Washoe Native Americans, Lake Tahoe is the center of their very existence. In respect to its beauty, the Washoe entitled the lake, “Da Ow ga” and believed Tahoe was the jewel of the Sierras. In my first experience with this jewel, Lake Tahoe captivated me the same way it has done to many others for thousands of years.
