Floods Triggered by Rising Narmada River in MP | 07 Jul 2025

Why in News? 

Heavy rains in Madhya Pradesh have resulted in the Narmada River overflowing, causing floods in several districts, particularly Shahdol.  

  • The rising water levels have prompted authorities to open the gates of the Bargi Dam in Jabalpur, raising concerns of further flooding.

Key Points 

  • Narmada River 
    • About:  
      • The Narmada is a major westward-flowing river in central India, traversing the states of Madhya Pradesh, Gujarat, and Maharashtra. 
      • The river is fed by 41 tributaries and historically served as a trade and cultural route between the Arabian Sea and the Ganges valley. 
    • Source and Course of the River: 
      • The Narmada originates from the Maikala Range in eastern Madhya Pradesh at an elevation of 3,500 feet (1,080 m) near the Chhattisgarh border. 
      • It flows through Mandla, Jabalpur, and the Marble Rocks Gorge, entering a rift valley between the Vindhya and Satpura ranges. 
      • The river crosses into Gujarat before draining into the Gulf of Khambhat through a 13-mile (21 km) wide estuary. 
      • The Narmada drains the northern slopes of the Satpura Range and flows through varied terrains, including the Dhuandhar Falls near Jabalpur. 
    • Water Resource Development: 
    • Narmada Water Dispute: 
      • Since the 1960s, several states have contested over the river’s water sharing and dam construction. 
      • In 1969, a tribunal was established to resolve disputes. The Narmada Control Authority (NCA), formed in 1980, implements the tribunal's decisions with representatives from Madhya Pradesh, Gujarat, Maharashtra, Rajasthan, and the Union government. 
    • Narmada Bachao Andolan (NBA): 
      • The Sardar Sarovar Dam faced strong opposition due to large-scale displacement. 
      • The NBA, led by Medha Patkar and Baba Amte, demanded proper rehabilitation for affected communities. 
      • Their efforts led to delays, World Bank withdrawal in 1993, and intervention by the Supreme Court. 
      • In 2000, the court allowed the dam’s completion in phases, conditional on the resettlement of displaced populations. 

Narmada River

  • Causes of Floods in India:  

Cause of Floods 

Explanation 

Heavy and Erratic Rainfall 

Excessive monsoon rains (June–September) often exceed the soil's absorption capacity and overwhelm drainage systems. 

Melting of Glaciers 

Rising temperatures accelerate glaciers and snowmelt in the Himalayas, increasing river discharge downstream. 

Cyclones and Coastal Storms 

Severe cyclones bring heavy rainfall, storm surges, and strong winds, flooding coastal and adjoining inland areas. 

River Overflow and Breaches 

Rivers exceed their banks due to upstream rain or reduced downstream discharge capacity. 

Unplanned Urbanisation 

Rapid, unregulated growth of cities and slums reduces natural drainage and increases vulnerability to urban floods. 

Poor Management of Dams and Barrages 

Inadequate regulation and emergency release from dams during heavy rain can worsen flooding downstream. 

Impact of Climate Change 

Global warming is leading to erratic and more intense rainfall patterns, raising flood risk. 

Inadequate Drainage Infrastructure 

Poorly maintained or clogged drains, especially in urban areas, lead to severe waterlogging during rain. 

  • Solutions for Flood Management in India: 
    • Interlinking of Rivers (ILR) Programme: 
      • The ILR programme aims to divert surplus water from flood-prone rivers to water-deficient regions, thereby balancing water availability. 
      • Example: The Ken-Betwa link project, a flagship initiative, is vital for water security and socio-economic upliftment in the Bundelkhand region. 
    • Reservoir Construction: 
      • Reservoirs store excess water during high rainfall and release it gradually to control downstream flood peaks. 
      • Example: The Bhakra Nangal Dam on the Sutlej River helps in flood moderation, power generation, and irrigation. 
    • Coastal Flood Management: 
      • Mangroves act as natural barriers against storm surges and coastal flooding, as witnessed during the 2004 Tsunami. 
      • The MISHTI initiative, launched in the Union Budget 2023–24, promotes large-scale mangrove plantations along India’s coasts. 
    • Flood Forecasting and Early Warning Systems: 
      • These systems use meteorological and hydrological data to predict floods and issue timely alerts. 
      • Example: The Central Water Commission (CWC) runs a nationwide network of forecasting stations issuing daily flood bulletins. 
    • Floodplain Zoning: 
      • This involves regulating land use in flood-prone zones to reduce vulnerability and preserve natural flood absorbers like wetlands. 
      • Example: NDMA’s floodplain zoning guidelines categorize land into four risk-based zones—prohibited, restricted, regulated, and free. 
    • Flood Insurance Schemes: 
      • Flood insurance provides compensation for losses in exchange for a premium, encouraging risk mitigation among vulnerable populations. 
      • Example: The Pradhan Mantri Fasal Bima Yojana (PMFBY) covers crop losses due to floods and other natural calamities.

Bargi Dam

  • About:  
    • Bargi Dam, located in Jabalpur, is one of the key dams among the 30 constructed on the Narmada River. 
    • It plays a crucial role in supplying water to Jabalpur city and its adjoining regions. 
  • Major Irrigation Projects: 
    • Two major irrigation initiatives—Bargi Diversion Project and Rani Avantibai Lodhi Sagar Project—have been developed based on this dam. 
    • These projects have enhanced agricultural productivity and improved water availability in the region. 
  • Emerging Tourist Destination: 
    • Over the years, Bargi Dam has evolved into a popular tourist attraction in Jabalpur, drawing visitors for its scenic views and recreational potential.
