Claim

India has never used its full share of the water; of the water India was permitted to use for consumption and power generation, it has used only about 20%.

“लेकिन भारत ने कभी अपने हिस्से का पूरा पानी इस्तेमाल नहीं किया। भारत को इन नदियों का जितना पानी इस्तेमाल करने और बिजली बनाने की छूट दी थी, उसका भी सिर्फ 20% ही हमने इस्तेमाल किया।”

Rationale

The claim repurposes a real but different statistic. The robustly documented ~20% is India's SHARE of the total Indus system (the Eastern Rivers), not the fraction of its permitted water it has used. In practice India uses roughly 90%+ of its Eastern-river entitlement, while genuine underutilization is concentrated in unbuilt storage and undeveloped hydropower on the Western Rivers. By recasting the '20% allocation' figure as a '20% of permitted use' utilization rate, the anchor conflates two distinct numbers; the underlying point (India underutilizes some permitted Western-river uses) is partly true, but the specific 20%-of-permitted claim is not supported by primary data and misrepresents the overall picture.

Evidence

• https://en.wikipedia.org/wiki/Indus_Waters_Treaty The well-documented '20%' figure refers to India's ALLOCATION under the treaty (the three Eastern Rivers, ~33 MAF), against Pakistan's ~80% (Western Rivers, ~135 MAF) — it is a share-of-total-system figure, not a measure of how much of its permitted water India has actually used. ✓ reachable · archived
• https://www.pib.gov.in/Pressreleaseshare.aspx?PRID=1565906 Government of India (PIB) status note shows India has substantially developed use of the Eastern Rivers (Bhakra, Pong, Ranjit Sagar dams, plus ongoing Shahpurkandi/Ujh projects), i.e. it uses the large majority of its Eastern-river entitlement — inconsistent with 'only 20% of permitted water used.' ✓ reachable · archived
• https://theprint.in/opinion/indus-water-irrigation-problems-generate-hydropower-india/2640783/ Underutilization is real but concentrated on the Western Rivers: India has built almost none of its permitted ~3.6 MAF storage and only a fraction of hydropower potential, while roughly 2-3.3 BCM of Eastern-river water still flows unused to Pakistan — a nuance the flat '20% of permitted use' claim obscures. ✓ reachable · archived
