Chief minister Naveen Patnaik said the flood had caused extensive damage to standing crops and properties in 12 districts.
The flood situation was under control as all rivers in south Odisha were flowing below the danger mark and it had become easier for relief teams to reach the inundated areas, Mohapatra said.
But, with heavy rain forecast in northern Odisha in the next 48 hours, the spectre of flood looms over Balasore, Bhadrak and Mayurbhanj districts.
The latest assessment by the state government is that over 16 lakh people in the state were affected on Friday in 4,611 villages of 10 districts in the second round of floods, which were triggered by a low pressure in the Bay of Bengal.
More than 2.29 lakh people were evacuated.
