Most of Haryana’s groundwater does not “flow out” as a single river but moves slowly underground and ultimately discharges into the state’s rivers, wetlands, and eventually the Yamuna–Ganga system and the Aravalli–Saharanpur–Chambal basins in different parts.

Basic direction of groundwater flow in Haryana

According to the Haryana Water Resources Atlas 2025 , the regional groundwater flow pattern in the state is broadly:

  • Southward : from the Rohtak–Yamunanagar area towards Bhiwani and the southern parts of the state.
  • Southwestward :
    • From Yamunanagar towards Kurukshetra, Kaithal , and
    • From Fatehabad towards Sirsa.
  • Northeastward : from the southern Aravalli region (around Rewari, Nuh, parts of Faridabad) towards the northeast.
  • Eastward : from Faridabad and Palwal towards the east, eventually feeding into the Yamuna corridor.

These directions are for the natural regional flow before heavy pumping and canal recharge distort local patterns.

Where does this groundwater ultimately go?

Groundwater in any region doesn’t have a single “destination” like a river; it gradually:

  1. Feeds streams and rivers
    • In north and central Haryana, groundwater discharges into the Yamuna and its tributaries (like the Sahibi, Dohan, and other seasonal streams).
 * In western Haryana, flow towards Sirsa and Fatehabad eventually connects with the **Ghaggar** system, a largely dry but hydrologically important river that historically fed into the **Saraswati–Indus system** and now mostly dissipates in the Rajasthan desert.
  1. Discharges into wetlands and low-lying areas
    • Groundwater rising in the southern Aravalli and nearby plains supports local wetlands, ponds, and seasonal water bodies that feed into the Yamuna and other river systems.
  1. Reaches the sea via major river basins
    • All surface water and groundwater that joins the Yamuna eventually reaches the Ganga , and then the Bay of Bengal.
 * Water that joins the **Ghaggar** system mostly evaporates or infiltrates in the desert, but hydrologically it is considered part of the broader **Indus–Saraswati** system.

So, in simple terms:
Haryana’s groundwater ultimately flows into the Yamuna–Ganga–Bay of Bengal system in the east, and partly into the Ghaggar/Indus-type system that dissipates in Rajasthan.

How human activities change the flow

In practice, the natural flow is heavily modified by:

  • Intensive irrigation pumping , which:
    • Creates local “flow towards borewells” instead of towards rivers.
    • Leads to declining groundwater levels, especially in the south and southwest (Faridabad, Palwal, Bhiwani, Mahendragarh, parts of Rewari).
  • Canal and flood recharge , which:
    • Adds water to the groundwater system in the northern and central belts (Yamunanagar, Kurukshetra, Karnal).
    • Can reverse or distort local flow directions near canal networks.
  • Urbanization in the NCR (Faridabad, Palwal, Gurugram side), which:
    • Increases extraction and reduces natural recharge.
    • Redirects groundwater flow towards withdrawal points rather than natural discharge zones.

Mini summary in bullet points

  • Groundwater in Haryana generally:
    • Flows south and southwest from the north and northwest.
    • Flows east from Faridabad–Palwal towards the Yamuna.
    • Flows northeast from the southern Aravalli region.
  • It ultimately discharges into:
    • The Yamuna–Ganga–Bay of Bengal system (eastern discharge).
    • The Ghaggar/Indus-type system that mostly dissipates in Rajasthan (western discharge).
  • Heavy pumping and canal recharge now dominate local flow, often overriding the natural regional directions.
