Flood Lines, Riverfront Development & Citizen Heroes: Story of Pune Floods
If a city deserved beautiful rivers only through the sheer will and efforts of its civil society, Pune would be a strong contender.
For decades Pune’s civil society has been remarkably active in protecting its rivers.

These sites are in Ganga, Narmada and Brahmaputra basins.
There are some sites where HFL has been breached in June and July 2023 also and peak flood level of these sites is given below the peak levels attained in August 2023.
