Gulf of Khambat · Gujarat, India
An ambitious 30 km dam across the Gulf of Khambat designed to create India's largest man-made freshwater reservoir, generate tidal energy, and transform the economic landscape of Gujarat.
The Kalpasar Project will harness the waters of the Sabarmati, Mahi, Dhadar, Narmada, Saurashtra Rivers, creating a freshwater reservoir upstream while enabling tidal energy generation, enhanced connectivity, and robust fisheries development.
SCHEMATIC · NOT TO SCALE
Dam Alignment
The dam alignment has been shifted northward to optimize its footprint — from Kala Talav village in Bhavnagar district to Aladar village north of Port of Dahej in Bharuch district.
The 30 km structure will serve simultaneously as a dam, a 10-lane highway, and a tidal energy installation — an unprecedented multi-purpose infrastructure asset.
Water Crisis Addressed
Over 30,000 MCM of Narmada river water flows unused into the sea every year due to inadequate storage — Kalpasar will capture this critical resource.
Project Benefits
Capturing surplus waters of major rivers to create a massive freshwater reservoir, preventing over 30,000 MCM of Narmada water from flowing into the sea annually.
Harnessing tidal fluctuations outside the reservoir post-dam closure to generate clean, renewable tidal energy for the region.
A 10-lane road over the dam dramatically reduces travel time between Saurashtra and South Gujarat, promoting economic and social integration.
Two major carp hatcheries to boost fresh and salt-water fisheries, supporting fishing communities in and around the new reservoir.
Reliable irrigation water supply through Kalpasar canals and channels across Saurashtra to transform farming productivity.
Meeting the industrial water demands of the Gujarat region, fuelling economic development and supporting manufacturing sectors.
Project Milestones
Feasibility studies and surveys commence in earnest.
By 2018, ₹250 crore had been spent on feasibility studies. DPR intended for completion by year-end.
By July 2019, 25 of 43 feasibility studies complete; 8 underway; 10 remaining expected by 2021–23.
Construction of Bhadhut Barrage — a smaller component — set to commence.
Environmental clearances, DPR finalization, and full-scale construction to follow.
