Bihar CM pushes Rs 6,282 crore Kosi-Mechi river link project toward 2029 completion

Bihar's Chief Minister Samrat Choudhary stood in Chainpur village, in Supaul district, on a Wednesday in August to inspect what may become one of the state's most consequential water projects. The Kosi-Mechi Inter-State River Link Project, still under construction, represents a 6,282-crore-rupee bet that the state can reshape how water flows across its agricultural heartland. Choudhary's visit was not ceremonial. He came to push, to check progress, to ensure that the machinery of government was actually moving toward the March 2029 deadline that officials had promised.

The project's logic is straightforward but ambitious. The Kosi River, which flows through Bihar with seasonal abundance, often carries more water than the region needs—water that swells into destructive floods. The Mechi River, which forms the border between Bihar and Nepal, runs lean. The plan is to build a link canal that diverts excess Kosi water into the Mechi system, a transfer that would serve multiple purposes at once. The Eastern Kosi Main Canal's capacity would increase from 15,000 to 20,000 cubic feet per second. Four branch canals, six distributaries, and associated canal networks would be constructed to carry that water where it is needed most.

The four districts of Seemanchal—Araria, Purnea, Kishanganj, and Katihar—would be the primary beneficiaries. In total, the project would bring assured irrigation to 214,813 hectares of agricultural land. The breakdown is precise: 69,642 hectares in Araria, 69,970 in Purnea, 39,548 in Kishanganj, and 35,653 in Katihar. For farmers in these districts, where water scarcity has long constrained yields, the difference between irrigated and rain-dependent farming is the difference between subsistence and surplus. The state government framed the project as a path to higher farm production, higher farmer incomes, and broader economic development across a region that has historically lagged.

During his inspection, Choudhary met with Water Resources Department Secretary Dr. Chandrashekhar Singh and Supaul District Magistrate Sawan Kumar. He reviewed construction progress and issued directives that reflected both urgency and caution. Officials were to maintain speed and quality simultaneously. They were to complete the work on schedule. But they were also to ensure that the construction itself did not burden the farming communities it was meant to serve—a tension that required active management, not passive hope.

Choudhary's broader vision extended beyond this single project. He directed officials to prepare a comprehensive plan for managing both the Kosi and Gandak rivers, with an eye toward building dams and other water structures that would sustain smaller rivers year-round. The Mechi diversion would discharge around 950 cusecs of water into that river system, expected to increase water availability in the Mahananda basin while simultaneously reducing flood pressure on the Kosi region. It was a vision of water as a resource to be orchestrated rather than endured.

The project sits within a larger portfolio of state initiatives. The cabinet had approved restoration work on canal systems under the "Har Khet Tak Sinchai Ka Paani" scheme—literally, "water to every field"—at a cost of 66 crore rupees across two restoration projects, both targeted for completion within two years. An additional 11,000 private tube wells would be installed in the next financial year, bringing the state's total to 46,000 and extending irrigation to roughly 230,000 hectares of additional land. The state was also moving forward with new cooperative sugar mills, an animal breed improvement scheme, a six-lane expressway project, and an artificial intelligence ecosystem development initiative. The Kosi-Mechi project was the flagship, but it was not alone.

What remained to be seen was whether the machinery of implementation could match the ambition of planning. Large irrigation projects in India have a mixed record. Cost overruns are common. Timelines slip. The gap between approved capacity and actual water delivery can be substantial. Choudhary's emphasis on continuous monitoring and timely completion suggested awareness of these risks. The March 2029 deadline was now less than three years away. The work was visible, the money was committed, and the Chief Minister had made it a priority. Whether that was enough would become clear only in the years ahead.
