The major river of Sikkim Tista originates from Cholamu Lake, it makes various tributaries along the way as it goes. Rangit is the major tributary of Tista which originates from Rathong glacier. No one can imagine that this innocuous-looking stream would transform into a thundering mighty river less than a hundred kilometers downstream. From an altitude of almost 5400 meters, the Tista plumes down in less than 80 kilometers to 1620 meters throughout about 100 kilometers.<\/p>\n<p>The other major tributaries of Tista River are Zemu (chu) River, Lonak Chu, Lachung Chu, Talung Chu, and Bakcha Chu, Tista River is a snow-fed river. Sikkim&#8217;s rivers flow fast and furious because of their potential of generating thousands of megawatts of electricity number hydropower has nestled in the state.<\/p>\n<p>Sikkim is one of the rainiest regions of India, Because of the mountainous region most of the parts of the state experience torrential rain during monsoon. But with the impact of climate change, rainfall pattern has become uneven. On 4th October 2023, there were heavy downpours which led to the Glacial Lake Outburst Flow due to the heavy flow Chungthang dam were burst leading to a more devastating situation for all the low-lying areas that lie along the river belt.\u00a0 Detailed description of the incident is explained below.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Flash_floods_in_Sikkim\"><\/span><a href=\"https:\/\/www.livemint.com\/news\/india\/sikkim-flash-floods-33-bodies-recovered-over-60-000-people-affected-10-things-we-know-so-far-11696817139682.html#:~:text=Sikkim%20flash%20flood%20was%20triggered,affected%2060%2C870%20people%2C%20reported%20PTI.\" target=\"_blank\" rel=\"noopener\"><em><strong>Flash floods in Sikkim<\/strong><\/em><\/a><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><strong><em><a href=\"https:\/\/en.wikipedia.org\/wiki\/2023_Sikkim_flash_floods\" target=\"_blank\" rel=\"noopener\">On 4th October 2023<\/a>, <\/em><\/strong>the picturesque Sikkim, nestled in the Himalayan foothills, the northeastern state of India experienced devastating flash floods. The tragedy was attributed to the GLOF from Lhonak Lake, which in turn, was set in motion by relentless heavy rains. The surge of water led to the catastrophic burst of the Chungthang dam, leaving destruction in its wake. This article delves into the sequence of events and their impact on North, East, and South Sikkim with far-reaching consequences of its residence.<\/p>\n<p>Sikkim, with its fragile climatic condition, is a region vulnerable to climate change impacts. The incident started with the Glacial Lake Outburst Flow in Lhonak Lake which is situated in North Sikkim. This glacial lake, nestled at an altitude, accumulated excessive glacial meltwater due to a rise in temperature and heavy rainfall. Eventually, the immense pressure resulted in the Lhonak Lake outburst, releasing a colossal volume of water downstream.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Chungthang_Dam_Disaster\"><\/span><em>Chungthang Dam Disaster<\/em><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The surge from Lhonak Lake cascaded downstream towards Chungthang, a small town located in North Sikkim. The Chungthang Dam, a vital structure for the region&#8217;s water management could not withstand the sheer force of the unleased water. The dam&#8217;s breach unleashed a torrent of water, creating a deadly flash flood on its path. This unexpected disaster caught the region off guard resulting a severe consequence.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Impact_on_North_East_and_South_Sikkim\"><\/span><strong><em>Impact on North, East, and South Sikkim<\/em><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>The flash floods wreaked havoc in North-East and East Sikkim, causing extensive damage to lives and property.
