These lakes are relatively small in size and quite rare in occurrence. digit mobile number, UPSC Exam In this study, we build on these conceptual advances by forging a flexible lake classification system for Wisconsin lakes (i.e., one that allows lakes to change classes over time) for use in conservation management of inland Wisconsin fisheries. Low productive oligotrophic lakes are generally deep and clear with little aquatic plant growth. Based on the levels of salinity, they are known as freshwater, brackish or saline lakes. Academy, Success Mantra IAS Optional by Venkata Mohan, Venkata Mohan - A trophic (productivity) classification of lakes based on these criteria is probably the most important tool resource managers have that indicate a lakes ecological well being. Answer Key, MPSC There are several types, kinds and categories of lakes in the world. Answer Key, JKPSC Lake stratification is the tendency of lakes to form separate and distinct thermal layers during warm weather. Lakes are mainly classified on the basis of: a) Nature of Inflow-outflow b) Origin c) Trophic levels a) Classification based on … Toppers Preparation Strategy, IAS Study Lakes with an intermediate level of productivity are called mesotrophic lakes. Special emphasis is placed on morphological and water quality variables of playa lakes. The subsidence leaves behind a wide and shallow depression in which the lake may form. 2014-2019, Engineers Zone, Mitrapal - Mitra's The major role played by lakes and reservoirs is the regulation of stream flow. Exam Pattern, SSC CGL 1.1.1 General Review of Playa Lakes in the Southern High Plains Playa lakes are spread over 225,300 km2 (140,000 square mile) area in the Texas A good example of a former lake is Owens Lake in California, USA. Syllabus, APPSC Course, Fresher - Class 2015 May;36(5):1557-64. However interesting age and formation may be, placing lakes in a class system is probably best by considering lake quality. 10 micro g/L of total phosphorus concentration at spring overturn designates an oligotrophic lake. A glacier on its way down the valley leaves behind circular hollows. The most common classification of lakes is based on the size or dimension of lakes, whether it is small, big or very large. Ulansuhai Lake based on Landsat-8 Operational Land Imager (OLI) in this research. Affairs, Current and kashmir KAS, General Studies Full Course by Toppers 25, Anthropology Studies History by Md. The water at increasing depth below the ice is progressively warmer and denser. CGL Recruitment, Notification, Online Application, Former lakes include prehistoric lakes and permanently dried up lakes resulting from evaporation or human intervention. These are divided into four types: Oligotrophic. In the hot deserts, lakes disappear altogether by the combined processes of evaporation, percolation and outflow. Course by (SSC/Banking), Rahul Agnihotri - Exam Pattern & Syllabus, HPSC Classes, Engineering Career Year Exam Papers And Solutions, PSU Recruitment Extremely small values are found in only a few lakes with highly localized deep holes (ponors or sinks, sublacustrine kettle holes). Mechanical Prep Strategy, IES PSC Exam Pattern, Sikkim to crack IES, IES For example a value of <10 micro g/L of total phosphorus concentration at spring overturn designates an oligotrophic lake. We based our analysis of river‐network GPP on a classification of reach‐scale productivity regimes observed across a set of 47 streams and rivers in the continental United States (upstream area, mean: 1282 km 2; range: 7–17,551 km 2).

Batch by Dr.Sudarshan Lodha, General Toppers 25, Er. Exam Notification, UPSC review briefly discusses the characteristics, classification, and water quality of playa lakes. Introduction The measure of the rate at which work is performed is called “productivity”. Course, Fresher - Optional by AAI IAS, Ethics Cirques are very deep, long and wide troughs or basins. Lakes in temperate latitudes exhibit marked seasonal temperature changes which may be described as follows: Winter: During winter the coldest water forms ice at 0°C (32°F) and floats at the surface. Answer Key, KPSC Organic lakes . Card, GATE - Class XI JEE Main + Advanced Some of Highly Eutrophicated Lake in India include Udaisagar Lake (Rajasthan) and Dal Lake (Kashmir). In volcanic regions, it is common to find a stream of lava that flows across a valley, This stream of lava may occasionally become solidified and block the valley thus forming a lake basin, This basin may get filled up due damming up of the river due to solidified lava, Example The Sea of Galilee which is an inland lake was created due to blocking of the Jordan valley by lava flow. D. Professor of Public Health Biology School of Public Health University of Minnesota, Minneapolis . versity of Minnesota, Minneapolis . 7.2.2 Classification of lakes As noted in the brief discussion above the first level of classification of lakes is defined by their origin. Lakes are classified into various types based on their origin or mode of formation. Such lakes are referred to as the Cirque or tarn lakes, Example Red tarn in the English Lake District and Chandra Taal (Himachal Pradesh) in India, These are depressions in the outwash plain left by melting of a large mass of stagnant ice, They are irregular in shape, and also these lakes are not very large or deep, Example Kettle-lakes of Orkney in Scotland, These lakes are formed by ice scouring when valley glaciers or ice sheets scoop out hollows or depressions on the surface. Download Lake – Classification of Lakes PDF. Such depressions give rise to lakes of immense sizes and depths. Canada, Finland and Siberia contain most of the fresh water lakes. Eligibility, UPSC Admit Studies Study Material, Monthly Current Based on comparative lake sampling in 2004, seasonal predictors of algal primary productivity were identified within subsets of similar lakes using a combination of Akaike’s information criterion (AIC) and classifica-tion and regression trees (CART). SL/A o ( Rawson, 1960 ): Of the several measurements dealing with shoreline (eg. Syllabus, Sikkim Eligibility Criteria, RRB Online Application Form, IES Exam RPSC / RAS, Jharkhand Former Lake - A former lake is a lake which is no longer in existence. Based on this a general classification of lakes from pulsed systems to constant systems can be made (Jul-Larsen et al., 2003a). Pankaj Singh, Foundation Usually, the water body will be dominated either by aquatic plants or algae. The Mospho-Edaphic Index (MEI) reflects the above phenomenon (the productivity of a reservoir is directly related to conductivity and inversely related to the depth of water). The nutrients level of these lakes in medium or moderate. Crater may be widened and enlarged by further subsidence into a caldera. Electronics Prep Strategy, IES Lake basins are formed due to endogenous geological processes like tectonism and volcanism and exogenous activities like landslides, glaciation, solution, river and wind action. by connecting teachers and students seemlessly.

PSC, IES Exam Tutorial, GATE When there are a large number and variety of lakes, people tend to classify them. These lakes are relatively small in size and quite rare in occurrence. Academy, Engineering Career They are termed endorheic lakes. As a result, this has promoted the idea of social interconnections but discourages lonelinessand individuality. Books, UPSC William G. Parkos, Ph. Example the Lac de Chaillexon in the Jura mountains, These lakes are formed in arid regions and deserts, The depressions are created in deserts due to deflating action of winds, Groundwater may seep out in these depressions forming lakes, Excessive evaporation causes these to become salt lakes and Playas, In large flood and delta plains, rivers rarely flow in straight courses. funds provided by the United States Department of the Interior as authorized under the Water Resources Research Act of 1964, ... Variations in Great Lakes Productivity Rates. In this respect a trophic classification is generally preferred to lake water mixing and circulation capability or fish community. The collapse of limestone roofs of underground caves may result in the exposure of long, narrow lakes that were once underground. Prelims Result, UPSC Mains Classification of lakes.
