Comparison with Other Major Indian Canals
While the Indira Gandhi Canal is the longest single line, India has several other massive canal systems:
| Canal Name | State | Key Feature |
| Buckingham Canal | AP & Tamil Nadu | 796 km long (a series of connected natural and artificial waterways). |
| Sharda Canal | Uttar Pradesh | The longest canal network in UP (approx. 938 km including all branches). |
| Narmada Canal | Gujarat & Rajasthan | Approx. 534 km; it is the world’s largest lined irrigation canal. |
| Sutlej Yamuna Link (SYL) | Punjab & Haryana | A major 214 km proposed freight/link canal (partially completed). |
Recent 2026 Update
With the assembly elections in Punjab and Rajasthan approaching, since early 2026, there has been re-emphasis on the Malwa Canal project in Punjab and the subsequent extension of lift irrigation schemes in Rajasthan to supply drinking water to the remotest border villages in Barmer and Jaisalmer districts
Frequently Asked Questions (F&Q)
Q, Which states does the Indira Gandhi Canal cross?
Which of the following was the by name of Indira Gandhi Canal?
Draft the news with a limited number of wordsThe project was initially named the Rajasthan Canal. The name was changed in 1984 after the assassination of Prime Minister Indira Gandhi.
Which rivers water this canal?

How many states does the canal runs through?
So, essentially the entire canal system runs over 3 states, Punjab, Haryana and Rajasthan. Nevertheless, most of its length and the major advantages is actually in Rajasthan.
What do we mean by a Lift Canal in this project?
With several parts of the Thar Desert lying higher than the main canal, water cannot flow there by gravity. Lift CanalsThese are the kind of canals that carry water to higher regions with the help of gigantic pumping stations, lifting the water up. Presently, the project has 07 Major Lift Irrigation Schemes.
Can you name the major crops cultivated due to this canal?
Water has enabled the farmers cultivate wheat mustard cotton, groundnut and chick peas on the barren sand dunes.
Will the canal be finished in 2026?
The main stages are all there though “Stage II” is an ever evolving process. The focus in 2026 has now shifted to lining the smaller distributaries to check water seepage and to enhancing the “tail-end” reaches to ensure that water reaches the far-flung border villages of Barmer.
What are the environmental issues with the canal?
However, the two major problems are waterlogging and rising salinity. In certain regions, overuse of water in desert soil (with low permeability potential) leads to a rise in the water table, bringing salts to the soil surface and rendering the land unsuitable for agriculture after some time.

Highlights of India’s Major Waterways
A top-quality Feat: The Indira Gandhi Canal, The Rajasthan Lifeline Not only did it give water, it prevented the Thar Desert from expanding. Here in year 2026, we are lifting desert water to high land villages using new “Lift Irrigation” technologies
The Buckingham Canal, which is unusual purely because it is also a navigation channel. The ridge running parallel to the Coromandel Coast served as an important buffer for many of the coastal villages when the Tsunami hit in 2004 and spared many of the villages by absorbing the influx.
Tahelka Engineering Heritage The Upper Ganga Canal is one of the oldest and most significant irrigation projects in the world, distributing water to the fertile “Doab” region located between the Ganges and Yamuna.
Entry points to the world: World Milestones in Western Transformation: The Narmada Canal The longest “lined” canal in the world (i.e. concrete-lined to avoid water seepage), bringing the waters of the Sardar Sarovar Dam into the water-deficient Kutch and Jalore regions.
F&Q Quick Guide

The Sharda Canal with a vast network of branches measuring nearly 1,000 km is the longest in UP.
If so, does that mean the Sutlej-Yamuna Link (SYL) has been commissioned?
Even as parts of the infrastructure are physically complete, the project is still a matter of legal and political contention between Punjab and Haryana, as of 2026.
What is the “Malwa Canal”?
A comparatively newer initiative based on how the Malwa belt’s irrigation network can be revived without overshooting groundwater usage (Announced/planned around 2024-2026).
Frequently Asked Questions
How do I book a property in Gurgaon and NCR?
Shortlist, visit, check the papers and RERA, then pay the booking amount and sign the agreement. Read the payment plan and cancellation terms before you commit.
Do I need a lawyer to buy property in Gurgaon and NCR?
For anything beyond a simple, clean deal it helps. A lawyer vets the title, the agreement and the approvals, which is cheap insurance against a costly mistake.
What is a builder-buyer agreement?
It is the core contract between you and the developer, setting the price, payment plan, area, specifications and possession date. Read it fully before signing.
What is an occupancy certificate and why does it matter?
It certifies a building is legally fit to occupy. Never take possession of a completed home without it, since it affects loans, utilities and resale.
What is mutation and why is it important?
Mutation updates the ownership in municipal and revenue records after a sale. Without it the property tax and records still point to the old owner, so get it done.
What credit score do I need for a home loan?
Lenders prefer a healthy score, usually in the mid-700s and above, for the best rates. A lower score can still get a loan but often at a higher rate.
Can I claim tax benefits on a home loan?
Yes, home-loan principal and interest carry deductions under the income tax rules, subject to limits and conditions. Confirm the current rules or ask a tax adviser.
What is the difference between freehold and leasehold?
Freehold gives you full, permanent ownership of the property and land; leasehold runs for a fixed term from an authority. Freehold is generally simpler to resell.
How do I check a builder's track record?
Look at delivered projects, delivery delays, the RERA record and buyer reviews. A builder with a clean, on-time record lowers your risk sharply.
What red flags should I watch for when buying?
Unclear title, missing approvals or RERA, pending dues, a builder with delays, and prices far below the market. If something feels rushed, slow down and verify.
What is the difference between capital appreciation and rental yield?
Appreciation is the rise in the property value over time; rental yield is the annual rent as a share of the price. Most Indian homes give modest yield and rely on appreciation.
How much should I keep as a buffer beyond the price?
Set aside for stamp duty, registration, GST where it applies, interiors, and a contingency. A buffer of a meaningful share above the base price is prudent.
Is a home loan pre-approval useful?
Yes, a pre-approved loan tells you your budget, speeds up booking and strengthens your negotiating position with sellers. Get it before you shortlist seriously.
How do I choose between two similar projects?
Compare the builder record, RERA status, carpet area, real amenities, connectivity and total cost, not just the headline price. Visit both before deciding.
What stamp duty and registration charges apply in Gurgaon and NCR?
Stamp duty and registration vary by state and are usually a few percent of the property value, with a small rebate for women buyers in many states. Confirm the current Gurgaon and NCR rate before you budget.
How much home loan can I get to buy in Gurgaon and NCR?
Most buyers get a loan for 75-90% of the value, tied to income and credit score. Our home loan by salary guide shows the ranges.
