Testalinden Creek
Testalinden Creek is a watercourse that flows east into the Okanagan River, south of the Okanagan town of Oliver, British Columbia. The Testalinden Dam was at the headwaters of this creek prior to the dam's failure in June 2010. Disasters The dam at Testalinden Lake located near the summit of Mt. Kobau burst on June 13, 2010 at around 2:15pm creating a debris torrent landslide that descended about 1500m to the valley below, destroying 5 houses, damaging several farms and blocking British Columbia Highway 97 Highway 97 is a major highway in the Canadian province of British Columbia. It is the longest continuously numbered route in the province, running and is the only route that runs the entire north–south length of British Columbia, connecting .... The overall damages were estimated to be over CAD$20 million. The dam was constructed in 1927 and was in poor maintenance at the time of failure. Two days before the breach, a hiker noted that Testalinden Lake was full and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stream
A stream is a continuous body of water, body of surface water Current (stream), flowing within the stream bed, bed and bank (geography), banks of a channel (geography), channel. Depending on its location or certain characteristics, a stream may be referred to by a variety of local or regional names. Long, large streams are usually called rivers, while smaller, less voluminous and more intermittent river, intermittent streams are known, amongst others, as brook, creek, rivulet, rill, run, tributary, feeder, freshet, narrow river, and streamlet. The flow of a stream is controlled by three inputs – surface runoff (from precipitation or meltwater), daylighting (streams), daylighted subterranean river, subterranean water, and surfaced groundwater (Spring (hydrology), spring water). The surface and subterranean water are highly variable between periods of rainfall. Groundwater, on the other hand, has a relatively constant input and is controlled more by long-term patterns of pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okanogan River
The Okanogan River (known as the Okanagan River in Canada) is a tributary of the Columbia River, approximately 115 mi (185 km) long, in southern British Columbia and north central Washington. It drains a scenic plateau region called the Okanagan Country east of the Cascade Range and north and west of the Columbia, and also the Okanagan region of British Columbia. The Canadian portion of the river has been channelized since the mid-1950s. Course The Okanagan River rises in southern British Columbia, issuing out of the southern end of Okanagan Lake, which is on the north side of the city of Penticton. It flows south past Penticton, through Skaha Lake, past Okanagan Falls, through Vaseux Lake, and past Oliver to Osoyoos and Osoyoos Lake, which spans the Canada–United States border and has its outlet into the Okanogan River at Oroville, on the southern shore of the lake, in Okanogan County. At the border the river's name (and the region and also the name of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Okanagan
The Okanagan ( ), also called the Okanagan Valley and sometimes the Okanagan Country, is a region in the Canadian province of British Columbia defined by the basin of Okanagan Lake and the Canadian portion of the Okanagan River. It is part of the Okanagan Country, extending into the United States as Okanogan County in north-central Washington. According to the 2016 Canadian census, the region's population is 362,258. The largest populated cities are Kelowna, Penticton, Vernon, and West Kelowna. The region is known for its sunny climate, dry landscapes, lakeshore communities, and particular lifestyle. The economy is retirement- and commercial-recreation-based, with outdoor activities such as boating and watersports, skiing, and hiking. Agriculture has been focused primarily on fruit orchards, with a recent shift in focus to vineyards and wine. The region stretches northwards via the Spallumcheen Valley to Sicamous in the Shuswap Country, and reaches south of the Canada� ...

Oliver, British Columbia
Oliver is a town near the south end of the Okanagan Valley in the southern British Columbia Interior, interior of British Columbia, Canada, with a population of nearly 5,000 people. It is located along the Okanagan River by Tuc-el-nuit Lake between Osoyoos and Okanagan Falls, and is labelled as the Wine Capital of Canada by Tourism British Columbia. It was once "The Home of the Cantaloupe" as well as the "Home of the International Horseshow." The community of Oliver is made up of land governed by three different bodies: the Town of Oliver, the Regional District of Okanagan-Similkameen and the Osoyoos Indian Band. Local industries include grape and fruit production, agritourism, Okanagan Valley (wine), wine production, ranching, golfing and recreation, retail and service trades. Some of the largest employers include Osoyoos Indian Band, School District #53, Interior Health and Okanagan Tree Fruit Cooperative.

River Source
The headwater of a river or stream is the geographical point of its beginning, specifically where surface runoff water begins to accumulate into a flowing channel of water. A river or stream into which one or many tributary rivers or streams flows has many headwaters, these being all of the individual headwaters of its tributaries. Each headwater is one of the river or stream's sources, as it is the place where surface runoffs from rainwater, meltwater, or spring water begin accumulating into a more substantial and consistent flow that becomes a Strahler number, first-order tributary of that river or stream. The tributary with the longest channel (geography), channel of all the tributaries to a river or stream, such length measured from that tributary's headwater to its mouth where it discharges into the river or stream, is the main stem of the river or stream in question. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
June 13, 2010 Oliver Mudslide Through Vineyard
June is the sixth and current month of the year in the Julian and Gregorian calendars—the latter the most widely used calendar in the world. Its length is 30 days. June succeeds May and precedes July. This month marks the start of summer in the Northern Hemisphere and contains the summer solstice, which is the day with the most daylight hours. In the Southern Hemisphere, June is the start of winter and contains the winter solstice, the day with the fewest hours of daylight out of the year. In places north of the Arctic Circle, the June solstice is when the midnight sun occurs, during which the Sun remains visible even at midnight. The Atlantic hurricane season—when tropical or subtropical cyclones are most likely to form in the north Atlantic Ocean—begins on 1 June and lasts until 30 November. Several monsoons and subsequent wet seasons also commence in the Northern Hemisphere during this month. Multiple meteor showers occur annually in June, including the Arietids, ...

Debris Flow
Debris flows are geological phenomena in which water-laden masses of soil and fragmented Rock (geology), rock flow down mountainsides, funnel into stream channels, entrain objects in their paths, and form thick, muddy deposits on valley floors. They generally have bulk density, bulk densities comparable to those of rock avalanche, rockslides and other types of landslide classification, landslides (roughly 2000 kilograms per cubic meter), but owing to widespread sediment liquefaction caused by high pore pressure, pore-fluid pressures, they can flow almost as fluidly as water. Debris flows descending steep channels commonly attain speeds that surpass 10 m/s (36 km/h), although some large flows can reach speeds that are much greater. Debris flows with volumes ranging up to about 100,000 cubic meters occur frequently in mountainous regions worldwide. The largest prehistoric flows have had volumes exceeding 1 billion cubic meters (i.e., 1 cubic kilometer). As a result o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Columbia Highway 97
Highway 97 is a major highway in the Canadian province of British Columbia. It is the longest continuously numbered route in the province, running and is the only route that runs the entire north–south length of British Columbia, connecting the Canada–United States border near Osoyoos in the south to the British Columbia–Yukon boundary in the north at Watson Lake, Yukon. The highway connects several major cities in BC Interior, including Kelowna, Kamloops, Prince George, British Columbia, Prince George, and Dawson Creek. Within and near these cities, Highway 97 varies from a two-lane highway to a Controlled-access highway, freeway with as many as six lanes. Some remote sections also remain unpaved and gravel road, gravelled. The route takes its number from U.S. Route 97, with which it connects at the international border. The highway was initially designated '97' in 1953. Route description The busiest section of Highway 97 is in West Kelowna, carrying almost 70,000 ve ...
