About Dholavira Reservoirs — Harappan Urban Hydraulics
3000–1800 BCE) on hyper-arid Khadirbet island in the Rann of Kutch, where monsoon 300 mm must be harvested. Sixteen monumental rock-cut and dam-fed reservoirs surround the walled town: the Eastern Reservoir 33×9? Actually Eastern Reservoir 77×16 m with 30 rock-cut steps, the Great Bath–like North Reservoir and twin city-wall reservoirs demonstrating Harappan urban process. Bisht's excavations 1990–2005 exposed check dams across Manhar and Mansar streams feeding a 12-km canal, spillways, filter drains and rock-cut wells 18 m deep with staircases.
Capacity >30,000 m³ made Dholavira viable for 800 years despite no perennial river, a desert Harappan innovation unlike Mohenjo-Daro Great Bath.
Why it mattersOnly Harappan desert hydraulic city showing complete monsoon harvesting without river, informing Indus collapse models.
