Kherkatta Reservoir

Kherkatta Reservoir, also known as Pakhanjore Reservoir,[1] is a man-made lake about 12 km (7.5 mi) north of Pakhanjore in Chhattisgarh, India. It was constructed by the Dandakaranya Development Authority under the project Dandakaranya Project[2] in 1958 to assist the refugees who sought a place to settle. Kherkatta is a Hindi word which means "Land of energy".[3]

The Kherkatta Reservoir (Kherkatta Dam)[4] was constructed over an area of 1,300 acres over an estimated cost of Rs 0.08 crores. The year of completion of Pakhanjore reservoir is 1964. The dam is an earth-fill embankment-type the Matholi river. The height above the lowest foundation is 20 m. The length of dam is 610 m and the gross capacity of the dam is 2,955,000 million m3.[5]

Report of completion of project

According to the report submitted on YOJANA July 18, 1965 Page 16, Irrigation canals are being built in the command area of Umerkote Dam and Pakhanjore Dam.One hundred families have been settled around the Pakhanjore Dam, and they will rear ducks and fish and also vegetables. A scheme has been drawn up for a dairy and poultry centre on the banks of the Kotri river in Paralkote zone.[6]

Benefits

The Kherkatta Reservoir was built in hopes of benefiting the locals with better irrigation and cultivation systems. The reservoir consists of two major gates which release water every couple of years through its canals. The artificial lake is used to store water.[7]

  • Local water supply
  • Distant water supply, if water is sent to cities via aqueducts
  • Local source of fishing & boating
  • Wildlife habitat
  • Increased water pressure for those living in the valley
  • Power generation
  • Irrigation
  • Flood water control

Ichthyofaunal diversity

The survey for Ichthyofaunal diversity study in the Pakhanjore Reservoir of Kanker District was mainly focused on Ichthyofaunal diversity. 25 Species of fishes belonging to 5 orders 11 family and 20 genera was recorded during the study. Cyprinidae were most dominant group represent by 12 species, Siluridae with 2 species, Ophiocephalidae with 2 species, Bagridae 1 species, Mestacemballidae with 2 species, Saccobranchidae 1 species, Claridae 1 species, Centropomidae 1 species, Notopteridae 1 species, Gobiidae 1 species and Cichlidae 1 species. This was the first ever study on the fish diversity of reservoir and would help in explore the fish fauna of Pakhanjore Dam.[8]

Low utilisation of developed water resources

The actual utilisation as compared with the designed potential is very poor, about 69%. The reason could be the low rainfall or the low maintenance of the canal system. [9]

gollark: What would be nice is if they'd let me remote-learn a few days a week as the in-person stuff will be pretty limited anyway, except nobody seems to have thought of that or considered that it might be a good idea some people might like?
gollark: So my school has sent out its plans to keep people socially distant and whatnot while at school during the term (starting in a week and a half or so), and they seem like they should actually be pretty effective (apart from the bits about not sharing pencils etc. and wiping down tables a lot, as apparently surface transmission is overrated). They would *also*, though, make lots of school things extremely annoying.
gollark: Random, but sure, some of them are useful chemicals I guess.
gollark: Still, 12 hours of work a day sounds like a great way to have problems.
gollark: Yeeees.
