In Lake Ummja, the color of the water has changed from blue-green to green, but the water hearing has decreased from 6 meters in 1906 to 3 meters in 2017.<\/p>\n<p><em><strong>Examining the general trend of the overgrowth of Lake Ummja, it can be concluded that a natural process takes place there,<\/strong> because the lake has a thick composition of organic materials, <\/em>throughout the long period from its origin to the present day, the lakes have been constantly evolving and changing. Neither of the lakes has retained its original form or content, because as soon as the depression is filled with water, the interaction between the two begins. On the one hand - water erodes and dissolves the bedrock and sedimentary rocks forming the depression, on the other hand - dissolved substances change the chemical composition of water.<\/p>\n<figure id=\"attachment_5691\" aria-describedby=\"caption-attachment-5691\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/daivings.lv\/daivings-ummja-ezera\/nirsana-ummja-ezera\/\" rel=\"attachment wp-att-5691\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-5691\" src=\"https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-300x225.jpg\" alt=\"Diving in Lake Ummja\" width=\"300\" height=\"225\" srcset=\"https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-300x225.jpg?v=1706275478 300w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-1024x768.jpg?v=1706275478 1024w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-768x576.jpg?v=1706275478 768w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-16x12.jpg?v=1706275478 16w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-1000x750.jpg?v=1706275478 1000w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-230x173.jpg?v=1706275478 230w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-350x263.jpg?v=1706275478 350w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera-480x360.jpg?v=1706275478 480w, https:\/\/daivings.lv\/wp-content\/uploads\/Nirsana-Ummja-ezera.jpg?v=1706275478 1200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-5691\" class=\"wp-caption-text\">Diving in Lake Ummja<\/figcaption><\/figure>\n<p>It is estimated that 1 mg of bacteria (Bacillus subtilis, Pseudomonas aeruginosa, Mycobacterium tuberculosis and Acidithiobacillus ferrooxidans) consumes up to 4 l of oxygen per hour. But a person who weighs 70 kg consumes only 22 liters of oxygen per hour during heavy physical work, which is many millions (100) times less than the weight of bacteria of the same weight. If there is a lot of algae, then all the sinking mass is usually not enough for mineralization, and part of the residue accumulates at the bottom of the lake in the form of undecomposed organic matter.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ezeros_izveidojas_bez_skabekla_zonas\"><\/span>Oxygen-free zones are formed in lakes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>At the same time, an oxygen-free area is formed in the deeper layers of the lake. In winter, on the other hand, oxygen disappears completely from the water for the same reason. Lakes are covered with ice, oxygen cannot enter from the air, photosynthesis does not take place, but overwintering plants, like animals, need oxygen to breathe. Oxygen is low in water, as it is mostly used in the decomposition of organic matter. Therefore, towards the spring, in lakes rich in plants and animals, fish are suffocated. The lakes will be enriched with oxygen at full depth only in spring and autumn, during the vertical circulation of water.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ezoros_mainas_krasas_dabiga_procesa_rezultata\"><\/span>The lakes change color as a result of a natural process<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In such lakes, the color of the water becomes darker and the clarity decreases very sharply. At best, water is<br \/>transparent at a depth of 5 - 6 m, usually at a depth of 1 - 3 m. Most of the water reaction is alkaline (pH&gt; 7)<br \/>and during the flowering of lakes - even strongly alkaline (pH 9). In the process of lake development, the oligotrophic type has changed<br \/>eutrophic (E). Plant feeding conditions in eutrophic lakes are excellent because of the accumulation of nutrients. Therefore, the substance and<br \/>there is an interruption in the circulation of energy.\u00a0<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Aizliegums_peldeties_Ummja_ezera_vasara\"><\/span>Prohibition to swim in Lake Ummja in summer<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In order not to disturb the flowering of this fragile and unusual plant, the Cabinet of Ministers Regulations No. 204 \u201cIndividual protection and use regulations of the nature park\u201c Piej\u016bra \u201d\u201d, which prohibits swimming and boating in Lake Ummja from 1 June to 15 August.<\/p>\n<p><strong>Related diving training courses led by a PADI MSDT diving trainer:<\/strong><\/p>\n<ul>\n<li><a href=\"https:\/\/daivings.lv\/padi-open-water-diver-owd\/\">PADI Open water Diver<\/a><\/li>\n<li><a href=\"https:\/\/daivings.lv\/advanced-open-water-diver-sertifikats\/\">PADI Advanced Open Water Diver<\/a><\/li>\n<li><a href=\"https:\/\/daivings.lv\/meklesana-zem-udens-ar-metala-detektoru\/\">Underwater search with a metal detector<\/a><\/li>\n<\/ul>\n<p>We prepare, train and certify divers.
