State on alert as Kosi, Gandak show signs of swelling amid rain in Nepal
Patna: With water levels already fluctuating in key rivers and forecasts warning of heavy rain upstream in Nepal, Bihar is on alert for potential flood-like conditions in the Kosi and Gandak basins starting Friday.
Officials have warned that the situation could worsen quickly, especially as the region heads into a wetter-than-average monsoon season.
On Thursday afternoon, water discharge through the Birpur barrage on the Kosi stood at 78,660 cusecs, a drop from 87,140 cusecs on Wednesday and 1.04 lakh cusecs on Tuesday, indicating unstable flow patterns. The Gandak, too, has seen considerable variation. While its discharge was recorded at 95,000 cusecs on Tuesday, it has since held steady at 47,000 cusecs for two consecutive days.
The state water resources department (WRD) flood bulletin has flagged concern, pointing to moderate to heavy rainfall forecast in the catchment areas of both rivers in Nepal over the next 48 hours. The Gandak basin is expected to receive rainfall ranging from 17.20mm to 57.32mm. Though other Nepal-fed rivers such as the Burhi Gandak, Bagmati, Adhwara, Kamla and Mahananda are forecast to receive only light rain, they will remain under observation.
Compounding the threat is a broader monsoon outlook. Nepal's meteorological department has predicted above-average rainfall this season while the Indian Meteorological Department (IMD) has also forecast higher-than-normal rain across India, including Bihar. Within the state, light to moderate showers are expected over Friday and Saturday, which may contribute to rising river levels.
Earlier this week, unexpected rain in Jharkhand and parts of Bihar triggered flash floods in the Jehanabad and Nalanda districts.
Swollen Lokain and Bhutahi rivers breached several zamindari bunds in Nalanda. In response to the damage and failure of embankment monitoring, state WRD minister Vijay Kumar Choudhary suspended the executive engineer of Ekangarsarai and six junior engineers. "Negligence of work by engineers and those responsible for embankment vigilance will not be tolerated," he said.
The WRD has since repaired the breaches and reinforced vulnerable points.
However, with monsoon momentum picking up and upstream rainfall imminent, the next 48 hours will be crucial for Bihar's flood management efforts.

Dams across state are nearly half full as monsoon sets in
Nagpur: It's the start of the monsoons, and dams across the state are nearly half full. The average level in all 2,997 dams across the state stands at over 41% as of Thursday. It was a little more than 20% on the same day last year. If the level increases quickly, there is a likelihood that water may have to be released earlier from some of the reservoirs, to prevent dams from breaching. This can increase the riverbed levels. However, it is too early to determine as the monsoon still has a long way to go. The dynamics of each dam are different. Normally, 80% of the level is maintained in the dams and rest of the water is released, said an official in the state's water resources department (WRD). The highest water level in dams is in the Konkan division, with 53.45%. On June 26, the water level stood at 29% in these dams. The least was in the Nagpur division, with 31.43%, which is 4% below the same period last year. At 39%, the dams have 2% more water than last year in the Amravati division. The Nagpur and Amravati divisions cover the eastern and western districts of the region. The Totladoh dam that feeds Nagpur city has 51% water, similar to last year's levels. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like The anime RPG everyone's talking about is finally free! Nikke: Goddess Of Victory Play Now Undo Even the Chattrapati Sambhaji Nagar division that covers Marathwada, which was parched last year, has 33% water in its dams. Last year, it was at 9.36%, according to the data maintained by the state's water resources department (WRD). The WRD categorises the dams as major, medium, and minor irrigation projects. The Gosikhurd dam, which is the biggest in the region, is 12% full; last year, it was 24% full. However, this is because water is being released through canals for irrigation and hydropower generation too. Increased usage has kept the level in Gosikhurd low this year, said sources.

As per India Meteorological Department (IMD), light to moderate rainfall is likely in different parts of Marathwada on Friday and Saturday. A yellow alert, indicating chances of thunderstorms, lightning, and heavy winds along with rainfall, has been issued for Chhatrapati Sambhajinagar and Jalna districts. K K Dakhore, an agricultural meteorologist with Parbhani-based Vasantrao Naik Marathwada Agricultural University, said revival of the monsoon in parts of Marathwada would lead to conducive conditions for the kharif crops.
