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.

Making Yamuna Flow Again

Guest Blog by Manoj Misra

It is no secret that the master key to Yamuna rejuvenation or for that matter any other perennial river is to make it flow as close to its natural flow pattern as possible. How to go about it is no rocket science but is no easy task either for we humans have burdened them with so many of our selfish stakes.

What flows in a river is not just water, but water enriched with energy, minerals, sediments, detritus and life, macro and microscopic plants and animals. It’s only such flow that enables and has enabled rivers over the millennia to fulfill various ecological (& social) functions like erosion and deposition of earth, meander and form floodplains, feed aquifers to replenish the ground water, host aquatic and riparian life forms, connect with the floodplain and its water bodies and complete the water cycle.
