Correct Option
The Farakka Feeder Canal, originating from the Farakka Barrage on the Ganga River in West Bengal, has a design carrying capacity of 40,000 cusecs (cubic feet per second). This canal is crucial for diverting water into the Bhagirathi-Hooghly river system. Its primary objectives include maintaining the navigability of Kolkata Port and regulating freshwater flow, particularly during lean seasons, thereby addressing siltation issues in the Hooghly River.
Incorrect Options
Options (a) 75,000 Cusecs, (b) 70,000 Cusecs, and (d) 35,000 Cusecs are incorrect. These values do not correspond to the officially established design discharge capacity of the Farakka Feeder Canal, which is 40,000 cusecs.
