Unprecedented Kerala deluge that swept through the coastal state on the day of Independence day 2018 was most disastrous flood incident in the year. It has also been termed as one the worst flood in the state and reminded the people of July 1924 and July 1962 flood calamities. Many experts, several reports and studies have established the role of dams in worsening the deluge. According to reports, 35 out of the 46 dams within the state were opened for the first time in history. All 5 overflow gates of the Idukki Dam were opened at the same time, for the first time in 26 years.
State Government Accepts Dams Role
Kerala is usually considered a flood-proofed state with its undulating terrain. For a state that receives an annual average rainfall of nearly 3,000 mm, its natural landscape protects it from recurrent floods. Indeed, the Kerala flood has highlighted our poor dam management system.
As per officials the crisis could have been contained had the state “gradually released” water from at least 30 dams, in advance of high rainfall, adding that local authorities failed to foresee the imminent danger with high rain predictions. “Such floods have probably recurred after 100 years, exposing the State’s unprofessionally run reservoirs management system and unpreparedness on disaster mitigation and disaster resilience.

Great to see this focus on aquatic biodiversity (unfortunately the article keeps using the word marine biodiversity, not using the word aquatic or freshwater biodiversity even once) along the 120 km long Sindhudurg Coast line, one of the 11 ecologically sensitive habitats identified along India’s coasts.
The FIRST study of local Otter Population by Ela Foundation identified upto 591 Smooth coated otters (strangely article does not mention about existence of small clawed Otters in Sindhudurg), 561 Indo Pacific humpbacked dolphins, among many others. The coast is particularly river rich with some twelve creeks/ rivers including Shanti, Piyali, Naringre, Achra, Gad, Talavade, Otawane and Pithdhaval Rivers.
The biodiversity here is facing multiple threats including rapid urbanisation, tourism onslaught with attendant plastic and sewage disposal, unregulated fishing trawlers, illegal sand mining, and global warming. It also underlines the need to do assessment of any interventions done in the area, of impacts on the aquatic biodiversity. http://www.hindustantimes.com/india-news/orphans-in-the-wild-what-the-otter-s-trying-to-tell-us-about-our-oceans/story-IfRFFi63Q8nV7UkUK4c16O.html (The Hindustan Times, 14 January 2018)
