Even as the flood situation in Jalka river is showing improvement with a fall in the water level, the incessant downpour lashing the State since the morning hours of today is likely to trigger severe flood situations in some blocks of Bhadrak and Baleswar during the coming 48 hours.
As the weather system will move over to Chhattisgarh by around 10-11 PM on Monday (Sept 13), the upper Mahanadi basin in the State is going to record very heavy rainfall in the range of over 5 -10 cm for the next 48 hours.
The data with IMD and CWC (Central Water Commission) reveals that the lower Mahanadi basin will be receiving a total of 6-10 cm rainfall by tonight.
Flood Situation In Mahanadi
Even as few places in the upper Mahanadi basin region in Odisha are predicted to record 9mm rainfall per hour on September 14, there is unlikely of any emerging flood situation in the Mahanadi river system, despite heavy rain forecast in Chhattisgarh.
As per the CWC data, the actual water level today in Hirakud reservoir stands at 189.91 mt today against the Full Reservoir Level (FRL) of 192.02 mt. The level is currently rising. The current inflow rate has been around 2500 cum/sec.
While the inflow rate is projected to double to around 7200cum/sec, the total inflow on Sept 17 is projected to touch 500 million cubic meters (MCM). But there is no flood threat in Mahanadi.
Flood Scenario In Other Rivers
As per data with CWC and Odisha Water Resources Dept, though the inflow will rise in the Brahmani and Baitarani basin, a flood threat exists in only some blocks of Bhadrak district. There is also a flood-like situation in some villages in the Balasore district, the data shows.
The water level at Akhupada is projected to remain above the danger level till the midnight hours of Sept 17. The actual water level currently is measured at around 16.8mt, and the inflow is high. It is predicted to cross the danger level in the next 72 hours.
However, the situation at the other gauge stations in the Brahmani-Baitarani is considered normal. And as per the inflow status, there is little possibility of flood-like conditions in other areas along the Brahmani-Baitarani river basin.
Though the western Odisha districts are going to record 25-100 mm rainfall, the data with Odisha Water Resources Department and CWC indicates no flood threat in other rivers like Tel, Bheden, Ong, Jonk and Ib.
As per the inflow forecast status, there is no flood threat in the Budhabalanga river basin. Moreover, even as the inflow into Bansadhara will rise to 150 MCM in the next 48 hours, there is no flood threat in the river basin, the inflow status forecast reveals.
