The following 12 states and union territories have no CWC-monitored storage reservoirs and appear as N/A on the map: Andaman & Nicobar, Arunachal Pradesh, Chandigarh, Dadra & Nagar Haveli, Daman & Diu, Delhi, Haryana, Jammu & Kashmir, Lakshadweep, Manipur, Puducherry and Sikkim. Together they account for less than ~1% of India's total water storage capacity — their reservoirs are either run-of-river schemes, canal headworks, or small HEP projects not tracked in the CWC Weekly Storage Bulletin.
