Indira Gandhi Nahar Pariyojana — IGNP
The Indira Gandhi Nahar Pariyojana — formerly called the Rajasthan Canal — is the single most transformative water infrastructure project in Rajasthan's history and one of the world's largest canal irrigation systems.
5.1 Basic Parameters
| Parameter | Detail |
|---|---|
| Headworks / Source | Harike Barrage, at confluence of Beas and Sutlej rivers, Ferozepur (Punjab) |
| Rajasthan Canal inception | 1958 (renamed Indira Gandhi Canal after PM Indira Gandhi's 1984 assassination) |
| Main canal length | 649 km (Harike to Mohangarh/Gadra Road) |
| Total canal network length | ~9,000 km including distribution canals |
| Irrigated command area | ~19.63 lakh hectares (designed); ~15.6 lakh hectares (actual irrigated as of 2023-24) |
| Districts benefited | Ganganagar, Hanumangarh, Bikaner, Churu, Jaisalmer, Barmer, Jodhpur |
| Water source allocation | Rajasthan's share: 8.6 MAF (million acre feet) under Indus Waters Treaty-linked allocation from Ravi-Beas waters |

5.2 Stage I and Stage II
Stage I:
- Length: 204 km (from Masitawali headworks to Pugal, Bikaner)
- Completion: 1972
- Command area: 5.53 lakh hectares (Ganganagar, Hanumangarh)
- Canals: Bikaner, Ferozepur Feeder — branches include the Gang Canal (built 1927 by Maharaja Ganga Singh of Bikaner, India's first modern irrigation project)
Stage II:
- Length: 445 km (Pugal to Gadra Road, covering Bikaner, Jaisalmer, Barmer, Jodhpur districts)
- Status: Largely complete; some extensions ongoing
- Command area: ~14.1 lakh hectares (target); transforms core Thar Desert
- Includes the Indira Gandhi Canal Command Area Development Programme (CADA)
5.3 Significance and Impact
- Demographic: Population of the IGNP command area grew from ~0.9 lakh (1961) to over 30 lakh by 2011 — a 30-fold increase demonstrating the project's transformative power
- Agricultural transformation: Before IGNP, Jaisalmer and Bikaner produced only bajra (millet) in low-rainfall years. Post-IGNP, wheat, cotton, mustard, groundnut are cultivated
- Drinking water: The Indira Gandhi Canal provides drinking water to Jaisalmer (100% dependent on IGNP for its urban supply), Bikaner, Barmer, and Jodhpur cities through feeder pipelines
- Ecological concern: Waterlogging and soil salinity (due to over-irrigation and inadequate drainage) have damaged ~3–4 lakh hectares of the original Stage I command area; the Rajasthan government's Drainage Master Plan (2020) addresses this through subsurface drainage channels
- Wildlife conflict: Canal water has attracted wildlife (blackbucks, chinkara) and also poachers; the Desert National Park buffer zone is intersected by canal infrastructure
