The Eastern Naro Canal: A Historical and Geographical Marvel of Sindh
Introduction
The Eastern Naro Canal, often referred to as the Hakro River or locally as "Karo Naro" (Black Canal), is a vital waterway in Sindh, Pakistan. Originating from Rohri city, this canal connects to the Sukkur Barrage and follows the ancient course of the Hakro River. Constructed during the British colonial period, it transformed an arid landscape into fertile farmland. This article explores its rich history, geographical significance, and modern-day challenges, making it a fascinating subject for history and geography enthusiasts.
Historical Background
The Eastern Naro Canal’s story begins in 1853 when the British government initiated its construction to irrigate the dry lands east of Rohri. Stretching 12 miles, the canal was completed in June 1859 at a cost of 5 lakh rupees. It linked the Indus River to the ancient bed of the Hakro River, a once-mighty waterway that dried up around 1226 AD. Historians believe the Hakro was a branch of the Sutlej River that once nourished the Thar region before shifting its course.
In 1859, Lieutenant Fife engineered the canal’s connection to the Indus, turning the old riverbed into an irrigation channel. By 1873, Colonel Le Mesurier oversaw upgrades, widening the canal to 156 feet and reinforcing its banks with stone pitching, costing 7,18,348 rupees. Further improvements in 1893 deepened it by half a foot and modernized its regulatory gates. When the Sukkur Barrage was completed in 1932, the original 12-mile canal was decommissioned, and the Eastern Naro was directly linked to the barrage, enhancing its irrigation capacity to a peak flow of 8,413 cubic feet per second.
Geographical Significance
The Eastern Naro Canal traces the path of the ancient Hakro River, which once flowed from the Himalayas through Sindh, irrigating the Thar Desert and parts of Rajasthan. Known by various names like Ghaggar, Sarasvati, and Naru, it supported lush vegetation and thriving settlements before drying up, leaving behind the arid Thar landscape. The canal’s revival of this riverbed brought water back to the region, making agriculture possible in areas like Rohri and beyond.
Today, it serves as both an irrigation lifeline and a drainage channel for rainwater and urban waste, though this dual role has led to pollution concerns. The canal’s historical connection to the Hakro River underscores its role in shaping Sindh’s geography and sustaining its agrarian economy.
Modern Developments and Challenges
While the Eastern Naro Canal remains essential for irrigation, its modern history is marked by challenges. After its integration with the Sukkur Barrage in 1932, the original canal route saw changes, including the construction of two bridges one for regulation and another for a railway line that operated until the 1977 floods. Over time, urban growth has encroached upon its banks, and pollution from sewage and industrial runoff has darkened its waters, earning it the name "Karo Naro."
Efforts to maintain the canal have been sporadic, with debris and illegal settlements reducing its efficiency. Despite these issues, it continues to support Sindh’s farmers, highlighting the need for conservation and cleanup initiatives.
Conclusion
The Eastern Naro Canal is a blend of historical ingenuity and geographical importance. From its British-era origins to its modern role in Sindh’s agriculture, it stands as a symbol of human efforts to harness nature. Preserving this canal is crucial not only for its practical benefits but also for honoring the legacy of the ancient Hakro River it follows.
