Okanagan Basin
The Okanagan Basin spans two countries and comprises the basin of Okanagan Lake, the Okanogan River and tributary valleys such as that of the Similkameen and Chelan Rivers. In Canada the basin constitutes two distinct regions within British Columbia, the Similkameen Country to the west and the main Okanagan region running from the communities of Osoyoos in the south to Armstrong in the north – incorporating most of the three Okanagan regional districts and is usually known as "the Okanagan" or as the Okanagan Valley or the Okanagan Country. In the United States, the Okanogan Country is the western, lowland core of Okanogan County, which like its Canadian counterpart has a history and economy based on ranching, gold, fruit orcharding and vineyards, but the basin includes Lake Chelan and other flanking valleys. Communities in Washington's Okanogan Basin include Pateros, Omak, Okanogan, Oroville and Brewster. Almost 200 km long and 8000 km2 in area, the Canadian p ...

Okanagan Lake
Okanagan Lake ( oka, kɬúsx̌nítkw) is a lake in the Okanagan Valley of British Columbia, Canada. The lake is long, between wide, and has a surface area of 348 km2 (135 sq. mi.). Hydrography Okanagan Lake is called a fjord lake as it has been carved out by repeated glaciations. Although the lake contains numerous lacustrine terraces, it is not uncommon for the lake to be deep only offshore. Major inflows include Mission, Vernon, Trout, Penticton, Equesis, Kelowna, Peachland and Powers Creeks. The lake is drained by the Okanagan River, which exits the lake's south end via a canal through the city of Penticton to Skaha Lake, whence the river continues southwards into the rest of the South Okanagan and through Okanogan County, Washington to its confluence with the Columbia. The lake's maximum depth is near Grant Island (Nahun Weenox). There are three other islands: one known as Rattlesnake Island, much farther south by Squally Point. The other two are near Gr ...

Omak, Washington
Omak ( Merriam (1997), p. 869) is a city located in the foothills of the Okanogan Highlands in north-central Washington, United States. With an estimated 4,845 residents as of 2010, distributed over a land area of , Omak is the largest municipality of Okanogan County and the largest municipality in Central Washington north of Wenatchee. The Greater Omak Area of around 8,229 inhabitants as of the 2010 census is the largest urban cluster in the Okanogan Country region, encompassing most of its twin city of Okanogan. The population has increased significantly since the 1910 census, reporting 520 residents just prior to incorporation in 1911. The land that is now Omak had been inhabited by various Native American tribes before the arrival of non- indigenous settlers in the early 19th century. The city began to develop after the completion of the Okanogan Irrigation Project affecting the Grand Coulee Dam and other nearby electric facilities. The housing and municipal infra ...

Okanagan Highland
The Okanagan Highland is an elevated hilly plateau area in British Columbia, Canada, and the U.S. state of Washington (where it is spelled Okanogan Highlands). Rounded mountains with elevations up to above sea level and deep, narrow valleys are characteristic of the region. Definition BC Geographical Names, a service of the British Columbia Integrated Land Management Bureau, defines the Okanagan Highland as an area extending southward from the Shuswap River and the Coldstream Valley, east of Vernon, British Columbia, for 85 miles to the 49th parallel and into the State of Washington, lying between the Monashee Mountains on the east, and the Thompson Plateau and the Okanagan Valley on the west. The eastern boundary of the Okanagan Highland is clearly defined by the valley of the Kettle River. The western boundary is drawn arbitrarily and is somewhat difficult to define, because there are no natural features to follow between Penticton in the Okanagan Valley and Lumby in the ...

Okanagan Basin Water Board
The Okanagan Basin Water Board (OBWB) is a water governance body designated to identify and resolve critical water issues for the Okanagan watershed in British Columbia, Canada. It was set up to implement the recommendations of the Okanagan Basin Study, and to take on a range of responsibilities for water management. The OBWB’s jurisdiction is defined by the geographic borders of the Okanagan Basin rather than political boundaries. Overview Water is one of the most precious and important natural assets in the Okanagan Basin. Even though the Basin is endowed with several large lakes, the supply of clean, reliable water is inherently limited by the semi-arid to arid climate, which brings minimal precipitation and high evaporation and evapotranspiration rates. In fact, according to Statistics Canada the Okanagan Basin has the lowest, per capita availability of fresh water in Canada. Water shortages have already occurred in some areas of the Basin, and are expected to occur more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causin ...

Agricultural Expansion
Agricultural expansion describes the growth of agricultural land ( arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself), with an estimated expectation of 10 to 11 billion humans on Earth by end of this century. It is foreseen that most of the world's non-agrarian ecosystems ( terrestrial and aquatic) will be affected adversely, from habitat loss, land degradation, overexploitation, and other problems. The intensified food (and biofuel) production will in particular affect the tropical regions. Most modern agriculture relies on intensive methods. Further expansion of the predominant farming types that rest on a small number of highly productive crops has led to a significant loss of biodiversity on a global scale already. ...

Population Explosion
Overpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources. The animals in an overpopulated area may then be forced to migrate to areas not typically inhabited, or die off without access to necessary resources. Judgements regarding overpopulation always involve both facts and values. Animals often are judged overpopulated when their numbers cause impacts that people find dangerous, damaging, expensive, or otherwise harmful. Societies may be judged overpopulated when their human numbers cause impacts that degrade ecosystem services, decrease human health and well-being, or crowed other species out of existence. Background In ecology, overpopulation is a concept used primarily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vancouver Island
Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian province of British Columbia. The island is in length, in width at its widest point, and in total area, while are of land. The island is the largest by area and the most populous along the west coasts of the Americas. The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel. This area has one of the warmest climates in Canada, and since the mid-1990s has been mild enough in a few areas to grow Mediterranean crops such as olives and lemons. The population of Vancouver Island was 864,864 as of 2021. Nearly half of that population (~400,000) live in the metropolitan area of Greater Victoria, the capital city of British Columbia. Other notable cities and towns on Vancouver Island include Nanaimo, Port Alberni, Parksville, Courtenay, and Campbell River. Vancouver Island is the ...

Oroville, Washington
Oroville is a city located in the northern bulk of the Okanogan Highlands in north-central Washington, United States. Oroville is a member municipality of Okanogan County, Washington, situated between Omak and Penticton. The population was 1,686 at the 2010 census. History Oroville was first settled by Caucasian settlers in the late 1850s and known as 'rag town.' The settlement was named Oro, after the Spanish word for gold, in 1892 after the surrounding gold mines and in an attempt to attract prospectors and merchants. The Post Office objected to the name "Oro" because a town was already named " Oso" in Washington, so the name was changed to Oroville, in 1909. Oroville was a stop along the Spokane Falls and Northern Railway line from British Columbia to Spokane, via Molson and Chesaw. In 1914 a third branch south to Wenatchee was constructed to avoid the steep inclines on the original Spokane track. Passenger train service to Oroville was operated by the Great Northern ...

Pateros, Washington
Pateros is a city in Okanogan County, Washington, United States. The population was 643 at the 2000 census and increased 3.7% to 667 in the 2010 census. History Pateros was originally established as Ive's Landing in around 1886 by Lee Ives. Ives began farming the area near the confluence of the Methow and Columbia Rivers, which was populated by a small band of Native Americans and around 20 Chinese miners. Ives also built an 18-room hotel at the town site and operated a ferry crossing. The first post office was built in 1895. In 1900, Charles Nosler acquired most of the townsite. He renamed the town to Pateros, after a town in the Philippines he previously visited. In 1903, the city consisted of four commercial establishments and nine residences and the town was sold to J.C.
