About flourishing life in the Chambal river

  • Forest department officials said improvement of quality of aquatic life in the Chambal river also caused an increase in the population of gharial (type of crocodile) by 17% and crocodiles by 24%, according to the survey.
  • Officials have identified the dolphin pools in 2019 and spotted 25 dolphin calves in Chambal river.
  • They have deployed Ghat (bank) in-charge near the pools to check illegal net fishing as it was a major reason behind the death of calves.
  • The dolphin population was falling every year between 2016 and 2020 but for the first time in six years the population has increased.
  • Experts feel the state government should come up with a plan to maintain this quality of aquatic life and habitat so that net fishing and sand mining does not increase once the lockdown is eased.

Chambal River

  • The Chambal River is a tributary of the Yamuna River in central India, and thus forms part of the greater Gangetic drainage system.
  • The river flows north-northeast through Madhya Pradesh, running for a time through Rajasthan, then forming the boundary between Rajasthan and Madhya Pradesh before turning southeast to join the Yamuna in Uttar Pradesh state.
  • The perennial Chambal originates at janapav, south of Mhow town, near manpur Indore, on the south slope of the Vindhya Range in Madhya Pradesh.
  • The Chambal and its tributaries drain the Malwa region of northwestern Madhya Pradesh, while its tributary, the Banas, which rises in the Aravalli Range, drains southeastern Rajasthan.
  • It ends a confluence of five rivers, including the Chambal, Kwari, Yamuna, Sind, Pahuj, at Pachnada near Bhareh in Uttar Pradesh state.
  • The Chambal River is considered pollution free, and hosts an amazing riverine faunal assemblage including 2 species of crocodilians – the mugger and gharial, 8 species of freshwater turtles, smooth-coated otters, gangetic river dolphins, skimmers, black-bellied terns, sarus cranes and black-necked storks, amongst others.
