Introduction to Jharkhand's Drainage System
The drainage system of Jharkhand holds great geographical significance.
The rivers of Jharkhand can be classified into two major categories:
(1) Southern Drainage System (rivers flowing into the Bay of Bengal)
(2) Northern Drainage System (rivers flowing northwards and merging into the Ganga)
The Subarnarekha, Shankh, and South Koel rivers fall under the first category, while the Damodar and North Koel rivers belong to the second category.
The watershed dividing these two systems runs roughly in an east-west direction across the Chotanagpur Plateau.

In the Chotanagpur Plateau region, several rivers flow through distinct routes, such as:
- Damodar River and its tributaries (flowing through Hazaribagh and Ranchi)
- North Koel River (in the northwestern part of the plateau)
- South Koel River (in the southwestern part)
- Subarnarekha River (in the southeastern part)
Major River Basins of Jharkhand
1. Damodar River Basin
- Flow Direction: West to east.
- Geographical Stretch: Between Ranchi Plateau and Hazaribagh Plateau.
- Nature: It occupies a faulted trough — a sunken section formed due to tectonic activity.
- Major Tributaries:
- Barakar River (forms a nearly independent valley),
- Konar River,
- Gobai River.
The Damodar Basin covers a large portion of the Chotanagpur Plateau and is heavily industrialized and coal-rich.
2. North-Eastern Drainage Basin
- Location: Northern and eastern part of the Chotanagpur Plateau.
- Major Rivers:
- Ajay River,
- Mor (Mayurakshi) River,
- Brahmani River,
- Gumani River.
- Course: These rivers originate from Jharkhand and flow eastwards or north-eastwards to merge into the Ganga River.
3. Subarnarekha River Basin
- Origin: Near Nagdi village, close to Ranchi city, in the Ranchi Plateau.
- Flow Direction: Southeast towards the Bay of Bengal.
- Major Tributary:
- Kharkai River (joins near Jamshedpur).
The Subarnarekha River is significant because it is one of the few rivers from Jharkhand that flows directly into the Bay of Bengal without merging into any larger river like the Ganga.
4. South Koel River Basin
- Origin: Southwestern part of the Ranchi Plateau.
- Flow Direction: Southwestwards.
- Major Tributary:
- Shankh River.
The South Koel and Shankh Rivers eventually combine and later merge into the Brahmani River system in Odisha.
5. Sone and North Koel River Basin
- North Koel River:
- Originates from the western part of the Ranchi Plateau.
- Flows through Palamu district.
- Major tributaries include Amanat, Auranga, Gohda, and Maila rivers.
- Finally merges into the Sone River, a tributary of the Ganga.
The North Koel and Sone river system is crucial for northern Jharkhand, providing irrigation and supporting biodiversity.
