On Aug 28 2024, the earthen wall of the Karchul Dam in Jetpur Tehsil of Shahdol district in Madhya Pradesh breached.

Will Sardar Sarovar AGAIN create avoidable flood disaster in Sept 2024?

India Meteorological Department (IMD) Flash Flood Bulletin (FFB) at 11.30 hours on Sept 1 2024[i] for “24 hours Outlook for Flash Flood Risk till 0530 hrs of 02-09-2024” includes large number of Narmada valley districts of MP. All this water is likely to come to Sardar Sarovar Dam as Big upstream dams like Bargi (96% full), Tawa (94%), Indira Sagar (97%) and Omkareshwar (72%) are all almost full and the soil in the Narmada basin is already almost fully saturated, all figures from the daily reservoir bulletin of Narmada Control Authority as on Aug 29 2024 (https://nca.gov.in/dailyreports.htm).

Role of dams: 2021 Flood Management In MP’s Sindh River

Guest Article by: Aishani Goswami and Rahul Singh

Walking through Dhimarpura village, in Seondha block, Datia district, Madhya Pradesh, heaps of broken clay tiles, wooden logs and other construction materials could be seen. Temporary tent-like shelters made of plastic sheets were erected in place of the houses that fell due to the floods in River Sindh in 2021.

In this article we try and put together available information to understand the role played by the Madhikheda system of dams in worsening the flood disaster in Sindh River basin in first week of August 2021. It may be noted that whenever a dam proposed, one of the claimed benefits is that the dams can help moderate floods in the downstream area. This is indeed true, provided, the dam is operated with the objective. However, when the dam is not operated with that objective, then the dam can actually end up acting like a force multiplier for the flooded downstream areas. Let us see if Madhikheda dam played that role in August 2021.

Legally enforceable Humane Rehabilitation, not compensation needed: Madikheda Dam in Madhya Pradesh

Guest Article by Bageshwer Singh and Pooja Chand

Dam construction on any river is often preceded by displacement of locals and followed by submergence of villages, turning them into ghost villages. All the major river water projects involve large scale displacement of locals, and most of these displacements lead to creation of vulnerable groups. The stories of displacement and forced evictions can be traced back to construction of dams like Sardar Sarovar Dam on river Narmada, or Tehri Dam on Bhagirathi or Hirakud Dam on Mahanadi. Almost always, these displacements are rife with little insight into the village specific consequences of dam construction, villagers are left with no option but to give up on their ancestral lands to move out to alien colonies with no land to their name. Arundhati Roy, in her essay, ‘The greater common good’, while arriving at the figure of number of people displaced in the developmental projects in the last fifty years writes, “Fifty million people. I feel like someone who’s just stumbled on a mass grave.”

Monsoon 2022: CWC Changing HFLs in Ad-hock Manner

During monsoon season, Centre Water Commission’s (CWC) carries flood monitoring and forecast work through a network of 332 stations[i] covering 20 major river basins. The stations are comprised of Level Forecast (LF), Level Monitoring (LM) and Inflow Forecast (IF) sites. The LF sites have Warning Level (WL), Danger Level (DL), Highest Flood Level (HFL), date of HFL information while LM sites maintain HFL and HFL date records. At IF sites flood level for respective dams/ barrages with inflow, out flow figures are measured and forecast is issued accordingly.

However, there are plenty of concerns plaguing CWC’s flood forecast and monitoring work across country for years. In this 2022 SW monsoon season, the agency has exhibited one more problematic tendency which exhibits not only its careless approach vis-a-vis keeping accurate information of HFL breach events, but it also seems strange that it realises it has giving wrong HFL level and date information mostly only after crossing the HFL now.
