8. HISTORY OF DAMODAR RIVER VALLEY
The records of the Bengal Government for the period show that the river breached its banks frequently. The Government was forced time and again to take up different plans for flood control works. Notably large floods caused wide spread damage in the years 1823, 1840, 1877, 1913, 1935, 1939, 1941, and 1943.
Flood control by means of reservoirs was considered as early as British Engineers wishing to locate dam sites surveyed one reservoir site in January 1864.
In 1902 a reservoir site was proposed at Barakar above the confluence of the Barakar and Usri Rivers. After the severe flood of 1913, a large reservoir was proposed once more for that site.
In 1919, the idea of using multiple reservoirs was conceived. The idea was to use three dams – one on Damodar river, one on the Barakar river and one on the Usri river.
Construction of Damodar Canal began in 1926.
The Governor of Bengal set up the Damodar flood enquiry committee in 1943 & its report (Aug 1944) suggests the creation of an authority similar to that of TVA.
