Why Upper Ganga Canal Runs Dry Between Dussehra and Diwali for Crucial Maintenance Water supply along the historic Upper Ganga Canal has been halted for 18 to 20 days between Dussehra and Diwali to facilitate silt clearing and structural repairs across 15 districts. The Upper Ganga Canal, which channels river water from Haridwar down to Kanpur Dehat in Uttar Pradesh, currently sits completely drained. Constructed during the British era primarily to support widespread agricultural irrigation, this expansive water network undergoes a scheduled annual closure during the festive window between Dussehra night and Diwali night. Spanning approximately 18 to 20 days, this planned shutdown reveals the canal floor, laying bare thick layers of accumulated silt, debris, discarded garments, and sediment. While the temporary stoppage directly interrupts canal irrigation for regional farmers, it also impacts pilgrims arriving at the famous Har Ki Pauri in Haridwar for holy dips and ritual ceremonies. The Engineering Logic Behind the Annual Shutdown Halting such a vital waterway every year follows a rigorous operational protocol. Vikas Tyagi, Executive Engineer at the Uttar Pradesh Irrigation Department, stated that the canal closure is an established annual event designed to carry out diverse maintenance tasks that are impossible to execute while water is flowing. Over months of uninterrupted flow, running water conceals structural wear, embankment erosion, and bed degradation. Once the gates are closed and water recedes, technical teams survey the bed to map damaged segments. Work plans prepared in advance are then merged with on-site assessments to restore ghat masonry and structural lining. Massive Silt Evacuation and Restoration Across 15 Districts The operational shutdown initiated at the Bhimgoda Barrage sets off coordinated engineering work not just in Haridwar, but across 15 districts including Aligarh. Vikas Tyagi explained that continuous annual operation causes extensive siltation and waste accumulation along the channel. Over these 18 to 20 days, engineering crews work around the clock to clear the accumulated silt, repair damaged sections, and reinforce the foundational infrastructure of the canal. The department has deployed teams on a war footing to ensure that every repair and renovation task is wrapped up before the festival deadline, enabling safe and unobstructed water release toward Kanpur Dehat right after Diwali. What this means for you The temporary 18 to 20 day water shutdown directly affects agricultural irrigation and ritual bathing across northern districts. • Across India: Pilgrims traveling from across the country to Haridwar will find significantly reduced water levels at Har Ki Pauri. Visitors planning holy dips will have to adjust to temporary reservoir arrangements until Diwali night. • In Uttarakhand and Uttar Pradesh: Farmers across 15 agricultural districts will face a temporary pause in canal water deliveries. Cultivators needing soil moisture must rely on tubewells or alternate local groundwater until normal discharge resumes. • Local Administration and Workforce: Engineering personnel in 15 districts face tight turnaround deadlines to finish structural upgrades. All ghat reinforcement and wall masonry must conclude before the gates reopen on Diwali night. • Canal Ecology and Efficiency: Massive dredging of accumulated silt and domestic debris cleans the waterway bed. Once refilled, the canal will operate with improved carrying capacity and reduced flow resistance. Why this happened The Upper Ganga Canal is intentionally closed between Dussehra and Diwali to excavate accumulated silt and repair underwater hydraulic structures. • Inability to Repair Under Water: Running water at high velocities makes it impossible to inspect or fix canal lining and bank erosion. Halting the flow allows engineers to evaluate the exposed floor and rebuild worn masonry. • Heavy Annual Silt Accumulation: Mountain runoff carries extensive sediment and debris downriver throughout the operating year. This silt settles on the canal bed, requiring an annual dry window for heavy machinery to dredge it out. • Traditional Maintenance Window: The period between Dussehra and Diwali provides an optimal window when agricultural water requirements reach a manageable phase. This historic schedule has been leveraged annually for planned rehabilitation across multiple districts. Questions & Answers 1. How many days is the Upper Ganga Canal shut down each year? The Upper Ganga Canal is completely shut down for approximately 18 to 20 days each year for routine maintenance. 2. What is the exact timeframe for this annual canal closure? The shutdown begins on the night of Dussehra and concludes on the night of Diwali. 3. What is the primary technical reason behind stopping the canal water? The closure is carried out to dredge accumulated silt and repair underwater masonry and damaged ghats that cannot be fixed during normal flow. 4. How many districts are covered during this maintenance period? Maintenance and cleaning operations take place across 15 districts including Aligarh, running between Haridwar and Kanpur Dehat. 5. Where does this canal originate and terminate? The canal originates at the Bhimgoda Barrage in Haridwar, Uttarakhand, and extends all the way to Kanpur Dehat in Uttar Pradesh. https://trendkia.com/en/uttarakhand/dashahara-se-dipavali-ke-bicha-upper-ganga-canal-kyon-ho-jati-hai-sukhi-janen-20-dinon-ki-isa-varshika-bndi-ka-pura-ganita-55017 TrendKia — Har trend, sabse pehle.
