Punjab Moves to Geo-Fence 850 Water Bodies, Launches Drone Mapping After Record Ravi Floods

Officials shift to geo-fenced buffers to cut flood risk using precise river elevation data.

Overview

  • Construction within 150 metres of notified drains will require a no‑objection certificate as the state geo‑fences roughly 850 rivers, tributaries and seasonal channels.
  • A memorandum with the Survey of India sets a one‑year timeline for digital elevation modelling of rivers and canals, supported by newly procured drones.
  • Preliminary estimates put plugging 45 embankment breaches at Rs 70–80 crore, with Rs 600–700 crore needed for comprehensive strengthening of dhussi bundhs.
  • The Ravi peaked at 14.11 lakh cusecs, exceeding its carrying capacity and causing 42 of Punjab’s 45 breaches across a 118‑km stretch in Pathankot, Gurdaspur and Amritsar.
  • After Ranjit Sagar levels crossed permissible limits and gates were opened, discharge surged and damaged infrastructure including two Madhopur barrage gates, prompting Punjab to seek stronger catchment‑area forecasts from the IMD.
