Vaitarna River
Why in News?
Two teenagers drowned in the Vaitarna River in Maharashtra’s Palghar district (near the Pinjal tributary) while attempting to record a social media reel during the Ganeshotsav holidays.
Origin and Course
- Origin: The river rises from the southern slopes of the Trimbakeshwar-Anjaneri hills in the Sahyadri range (Western Ghats), located in the Nashik district of Maharashtra.
- Proximity to Godavari: Interestingly, its source is just 2 kilometres away from the origin of the Godavari River, India's second-longest river.
- Flow Direction: It is a west-flowing river that runs for about 154 kilometres before emptying into the Arabian Sea.
- Regions Covered: It drains parts of the Nashik, Thane, and Palghar districts. It is the largest river in the Northern Konkan region.
- Estuary & Mouth: The islands of Jhow and Wadhiv lie in its estuary, while Arnala Island sits right off its mouth.
- The "Titanic of Gujarat": A historic passenger steamship named SS Vaitarna (popularly known as Vijli or Bijli) disappeared in a heavy cyclonic storm in the Arabian Sea in 1888, taking down hundreds of passengers.
Hydrology and Climate
- Rainfall Dependent: The river is highly seasonal, receiving 98% of its annual rainfall from the Southwest Monsoon between June and October.
- Tributaries: Its primary tributaries include the Tansa, Pinjal, Surya, Alvand, Ganjai, and Dahanu (Deharji) rivers.
- Pollution: Despite its pristine origin in the Western Ghats, the river faces heavy industrial and urban pollution as it approaches the Mumbai Metropolitan Region.
- Dam Discharge Risks: Nearby tribal settlements often face severe safety hazards and drowning risks due to sudden water surges caused by upstream dam operations.
Lifeline of Mumbai
- Water Supply: The Vaitarna is crucial for urban infrastructure; over 60% of Mumbai's drinking water is supplied by this river and its connected dams.
- Major Dams: The mainstem features three prominent reservoirs: Upper Vaitarna, Middle Vaitarna, and Modak Sagar (Lower Vaitarna).
