Kalamalka Lake
Kalamalka Lake ( "Kal Lake") is a large lake in the interior plateau of southern central British Columbia, Canada, east of Okanagan Lake. The lake is located approximately south of the city of Vernon and is its main drinking water supply. The lake is named after the Okanagan (''Okanogan'' U.S. spelling) First Nation chief who occupied its northern shores. At different times of the year the colour of the lake can range from cyan to indigo, in different parts at the same time, earning the lake the moniker "lake of a thousand colours". The colour of the water is derived from light scattering, caused by the precipitation of calcium carbonate (CaCO3). Hydrology Kalamalka Lake is an oligotrophic, monomictic marl lake with high alkalinity and hardness. From fall to spring the entire water column mixes and is thermally stratified in May through early November. During periods of warmer weather and increasing photosynthesis of phytoplankton, calcium, carbonate ions, and phosphorus i ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Water
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters.World Health OrganizatioHardness in Drinking-Water 2003 Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects. Origins Natural rainwater, snow and other forms of precipitation typically have low concentrations of multivalent cations such as calcium and magnes ...

Kalamalka Lake Provincial Park And Protected Area
Kalamalka Lake Provincial Park and Protected Area is a provincial park in Coldstream, British Columbia, Canada. Located within the Okanagan region, the park encompasses a land area of about of pristine natural areas in the North Okanagan Regional District. Kalamalka Lake Provincial Park and Protected Area adopted its current name from Kalamalka Lake, for which it is located on its shore. During the process of entering summer, calcium carbonate forms crystals that reflect sunlight and create the vivid blue and green colours. Temperature changes in the fall and the spring sometimes create ribbons of deep blue colour in the lake, seen from the park. The park is a preserved remnant of the natural grasslands that once stretched from Vernon to Osoyoos. There are several forests and cross-country ski trails available throughout the year, along with two archaeological sites. Mammals include coyote, deer, black bear, Columbian ground squirrel, marmot Marmots are large ground squ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winter Morning Over Kalamalka Lake - Panoramio
Winter is the coldest season of the year in polar and temperate climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the winte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wood Lake (British Columbia)
Wood Lake is a lake in a chain of five major lakes which occupies portions of the Okanagan Valley in the interior of British Columbia, Canada. The lakes of the Okanagan Valley were formed by about 8900 BP. Wood Lake is immediately south of Kalamalka Lake and in 1908 was connected to it by a dredged channel (the Oyama canal). Situated between Oyama and Winfield, it has a solid reputation for rainbow trout fishing. The lake is named after Tom Wood, who settled on the south end of the lake around 1860. The dry climate and suitable soil has encouraged development of a substantial tree fruit industry around the lake and throughout the valley. The upper watershed is heavily forested and has been logged for several decades. The lower elevation of the watershed is described as a Ponderosa pine/ bunchgrass area. Physical data *Normal range of annual water level fluctuation: 1.2 m *Number of beaches: 4 There is also a Wood Lake in Fraser Valley, an area of British Columbia. ...

Charophyta
Charophyta () is a group of freshwater green algae, called charophytes (), sometimes treated as a division, yet also as a superdivision or an unranked clade. The terrestrial plants, the Embryophyta emerged within Charophyta, possibly from terrestrial unicellular charophytes, with the class Zygnematophyceae as a sister group. The clade Streptophyta may be formed by placing Embryophyta within the Charophyta. The Embryophyta may already be included in the Charophyta, in which case it is a synonym of the Streptophyta. The sister group of the charophytes are the Chlorophyta. In some charophyte groups, such as the Zygnematophyceae or conjugating green algae, flagella are absent and sexual reproduction does not involve free-swimming flagellate sperm. Flagellate sperm, however, are found in stoneworts ( Charales) and Coleochaetales, orders of parenchymatous charophytes that are the closest relatives of the land plants, where flagellate sperm are also present in all except the coni ...

Turbidity
Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air. The measurement of turbidity is a key test of water quality. Fluids can contain suspended solid matter consisting of particles of many different sizes. While some suspended material will be large enough and heavy enough to settle rapidly to the bottom of the container if a liquid sample is left to stand (the settable solids), very small particles will settle only very slowly or not at all if the sample is regularly agitated or the particles are colloidal. These small solid particles cause the liquid to appear turbid. Turbidity (or haze) is also applied to transparent solids such as glass or plastic. In plastic production, haze is defined as the percentage of light that is deflected more than 2.5° from the incoming light direction. Causes and effects Turbidity in open water may be caused by growth of phyto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as do trees and other plants on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half of the oxygen production, despite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name ''photosynthesis'', from the Greek ''phōs'' (), "light", and ''synthesis'' (), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromoph ...

Thermal Stratification
Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Typically stratified lakes show three distinct layers, the Epilimnion comprising the top warm layer, the thermocline (or Metalimnion): the middle layer, which may change depth throughout the day, and the colder Hypolimnion extending to the floor of the lake. Definition The thermal stratification of lakes refers to a change in the temperature at different depths in the lake, and is due to the density of water varying with temperature. Cold water is denser than warm water and the epilimnion generally consists of water that is not as dense as the water in the hypolimnion. However, the temperature of maximum density for freshwater is 4 °C. In temperate regions where lake water warms up and cools through the seasons, a cyclical pattern of overturn occurs that is repeated from year to year as the cold dense water at the top of the lake sinks (see stable and unstable st ...
