This annual overview highlights the critical issue of siltation in dams across India. Silt accumulation is defeating the very ‘multi-purposes’ for which they were built. While the reduced storage has been hampering dam-based water supplies, it is also leading to their fast filling up and untimely releases in monsoon season thus creating avoidable floods. It is in some case has also been resulting in plans to construct additional reservoirs and increase in dam height.

India has witnessed several incidents of dam induced floods during south west monsoon 2025. The most remarkable and devastating episode unfolded in Punjab and Himachal Pradesh states in August 2025 largely due to mismanagement of Bhakra, Pong and Ranjit Sagar dams by BBMB. While negligence of BBMB has invited FIRs in Himachal Pradesh, warnings by Punjab govt and petition in NGT, there is no report in public domain suggesting the authority taking any credible action to make its dam operation scientific and accountable after the disaster.

The annual Renewable Statistics 2023 report from IRENA (International Renewable Energy Agency) says that globally, only 1.6% was added to the hydropower capacity in 2022, that too two thirds in non-democratic China. The capacity added in rest of the world outside China in 2022 was 7.3 GW, lowest figure in last 15 years. Similarly 99% of additional capacity added in pump storage projects in 2022 was in China. The report from IRENA also says that 97% of hydropower finance comes from public or government sources and private sector seems to have little enthusiasm for this sector. The projections for future painted in the report is no better. This is broadly in line with our lead story in DRP News Bulletin last week (dated March 27 2023) painting bleak future of large hydropower projects.

DRP News Bulletin 23 July 2018: Landmark CAG Reports on DAM FLOODS & Ineffective; Costly Mega Irrigation Projects

July 23, 2018July 23, 2018 SANDRPLeave a comment

In its latest report, the Comptroller and Auditor General (CAG) has questioned implementation of sixteen National Irrigation Projects. Before this, the CAG has held mismanagement in dams’ operation responsible for Chennai floods in 2015. Both these reports are available on its website now.

The CAG report on National Irrigation Projects, tabled in Parliament on July 20, has revealed that sixteen major multi-purpose water projects, taken up on an expeditious basis about a decade ago, are nowhere near completion, with no work being undertaken in as many as 11 projects despite the incumbent govt’s much-wanted focus on improving irrigation facilities in the country.

The report also mentioned that out of the 16 projects, undertaken under the Accelerated Irrigation Benefits Programme (AIBP) in Feb 2008, only five projects with estimated irrigation potential of 25.10 lakh hectares were under implementation and even these projects suffer from 8 to 99 per cent shortfall in physical progress, the CAG said. The remaining 11 projects with estimated irrigation potential of 10.48 lakh hectares are yet to commence and are at different stages of approval.
