Officials said 200 people were saved in Chirang district, while in Bongaigaon 150 people were saved from drowning.
The Army even conducted a medical camp in Kokrajhar attending to 100 patients. Army officials said they received distress calls from the populace of Chirang and Bongaigaon in the late afternoon asking for succour from flood water.
Reacting swiftly to provide humanitarian assistance, the Army launched one column in Chirang and two columns in Bongaigaon with boats.
The Army personnel waded through rushing currents and their boats ploughed through in a bid to rescue marooned people.
Based on earlier experience and lessons learnt in the recently concluded disaster preparedness exercise Jalrahat, the Army has pre-placed flood relief equipment at designated places for their swift employment on need basis in the shortest possible time frame, the officials said.
