Bhakra’s Inflow Crisis: When Climate Stress Meets Structural Neglect and Poor Maintenance……by KBS Sidhu

The dam is receiving half its normal water at peak demand — and the warnings go deeper than the headline numbers

I. The Tribune Report: A Warning in Plain Numbers

Lalit Mohan’s report in The Tribune of 12 June 2026 deserves careful attention. Inflows into the Bhakra reservoir on June 11 stood at 16,527 cusecs — barely half the seasonal average of 32,706 cusecs and well below last year’s 28,015 cusecs on the same date. Cumulative inflows from May 21 to June 11 measured 0.74 BCM against a historical average of 1.45 BCM.

The root cause is a severely depleted Sutlej snowpack: only 2.2 BCM of snowfall was recorded this winter against a normal 4 BCM. Persistent western disturbances have compounded the problem by suppressing high-altitude temperatures to around 4 degrees Celsius, below the 6–8 degrees needed for meaningful snowmelt to begin.

Releases are already exceeding inflows by nearly 7,000 cusecs daily, drawing the reservoir down by 0.70 feet every day. The higher-than-average current reservoir level of 1,576.65 feet is a lagging indicator of carry-over storage, not evidence of current hydrological health. The coming fortnight, before the monsoon arrives, is the critical window.

II. The Dehar Dimension: When Silt Destroys the Turbines That the Water Moves

It is significant that the same correspondent, Lalit Mohan, reported in The Tribune in March 2026 on a crisis that directly compounds today’s inflow emergency — the complete operational collapse of the Dehar Power Plant. The two reports, read together, tell a single story of compounding institutional failure.

The inflow crisis at Gobind Sagar does not begin at Bhakra Dam. It begins at Pandoh, where the Beas–Sutlej Link carries water through the Dehar powerhouse before discharging it into Gobind Sagar.

The plant’s six Francis turbine units of 165 MW each — 990 MW in all — serve a dual purpose: generating peak power and transferring Beas waters into the Sutlej. When Dehar stops generating, it also stops transferring water. Since March 4, 2026, official data confirms no water diversion through the BSL system whatsoever.

Units 1 and 2 were already under maintenance when Unit 3 broke down in February due to excessive vibrations and Unit 4 followed in March due to leakage. All six units are now non-functional.

This is not a sudden catastrophe but the culmination of a long and inexcusably mismanaged decline. Since 2022, power output has been falling steadily due to silt ingress eroding turbine components. Due to the Beas’s heavy Himalayan silt load, two turbines require capital maintenance annually — a known engineering reality since commissioning in 1977.

BBMB’s failure has been to allow the maintenance cycle to collapse entirely, so that instead of two units in rotation with four running, all six are simultaneously broken or under repair. Environmental restrictions limiting dredging to three months annually have complicated matters, but BBMB has devised no workaround across four consecutive years.

Punjab has demanded a third-party audit and a firm repair timeline. BBMB has responded with a project report for eventual Renovation, Modernisation, Uprating and Life Extension. A planning document is not a repair schedule. It does not restore a single cusec of Beas water into Gobind Sagar — which, already receiving half its normal snowmelt inflows, has been additionally deprived of BSL augmentation since early March.

III. The Compounding Risk Factors

The snowpack and Dehar crises do not exhaust the risk register. The siltation burden on Gobind Sagar itself is a structural problem of long standing. Bhakra’s live storage capacity has declined steadily as sediment accumulates on the reservoir bed, reducing the buffer available precisely when inflows are abnormally low. The timing is further cruelled by the paddy season: Punjab and Haryana have transplanted paddy across millions of hectares in the past fortnight, the most water-intensive agricultural operation in northern India, driving releases well above inflows at the worst possible moment.

If inflows do not recover meaningfully after June 21 — uncertain given the snowpack deficit — the drawdown will accelerate through July. Additionally, Bhakra has been the subject of documented engineering concern regarding tilt beyond permissible limits.

A dam under structural stress responds differently to rapid drawdown-and-refill cycles than one operating within design parameters. These cycles, in a structure already exhibiting anomalous behaviour, demand rigorous scrutiny that the present BBMB institutional arrangements are not equipped to provide.

IV. What Must Be Done

The Bhakra system faces a convergence of four simultaneously active crises: climate-driven snowpack depletion, mechanical collapse at Dehar, structural siltation of Gobind Sagar, and institutional inadequacy at BBMB. The Dehar shutdown must be treated not as a maintenance matter but as a national infrastructure emergency, with a war-room accountability mechanism, authority to fast-track BHEL procurement, and power to direct year-round dredging without waiting for the annual three-month environmental window.

The Central Water Commission must publish a current volumetric assessment of Gobind Sagar’s live storage capacity — the last comprehensive public survey is dated, and planning on the basis of design-era figures is denial dressed as administration. An urgent hydrological assessment of long-term snowpack trends in the Sutlej catchment must be commissioned: if 2.2 BCM is the new normal rather than an outlier, the entire allocation envelope for irrigation, drinking water, and power must be recalibrated. Finally, BBMB must be restructured with an independent technical oversight board on statutory footing, insulated from the inter-state political pressures that currently override engineering judgement.

V. The Larger Warning

Bhakra’s reliability over six decades rested on three foundations: adequate Himalayan snowpack, sufficient live storage, and sound institutional management. Today all three are simultaneously under stress. The snowpack is depleted at source. The storage is eroding at the base. The machine that transfers augmentation water from the Beas has been silent since March 4.

And the institution responsible for managing the whole is answering demands for repair timelines with planning documents for eventual renovation. The June 2026 numbers are not a seasonal inconvenience. They are a signal. Water does not wait for committees to meet.
