abruptly in the monsoon. |
| Andhra River : |

and merges with the Pabbar river at Chigaon. |
| Giri River : |

Yamuna river. It drains a part of South-Eastern Himachal Pradesh.
The Giri or Giriganga as it is famous in the Jubbal, Rohru hills
that rises from Kupar peak just above Jubbal town after flowing
through the heart of Shimla hills, flows down in the South-Eastern
direction and divides the Sirmaur district into equal parts that
are known as Cis-Giri and Trans-Giri region and joins Yamuna
upstream of Paonta below Mokkampur. The river Ashni joins Giri
near Sadhupul ( Chail ) while river Jalal which originates from
Dharthi ranges adjoining Pachhad joins it at Dadahu from the
right side. The waer from the Giri river is led through a tunnel
to the power house of Girinagar and after that it is led into
the Bata river. |
| Asni River : |
The Ashni river is a tributary of the Giri river
which in turn drains into the Yamuna river. This river flows
along a deep V shaped valley whose side alopes vary from steep
to precipitous. It has carved a steep gorge across the off-shoots
of the Nag Tibba ridge. Numerous small spring fed tributaries
join the Ashni river at various places along its course. |
| Bata River : |
This river originates in the boulders below the
Nahan ridge in the South-Western corner of Himachal Pradesh as
the Jalmusa-Ka-Khala. It is mainly fed by the rain water that
is cycled as underground water before finally coming up on the
surface as a spring. The river flows below the surface for a
part of its length in its upper reaches, thereafter the water
flows on the surface. Large and wide terraces have been formed
by it. The small tributaries which join the Bata river in the
Paonta valley are Khara-Ka-Khala flowing in a Southerly direction
from the Nahan ridge, and Kanser-Khala originating from the Southern
slopes of the Nahan. |
| Pabbar River : |
The Pabbar river is a tributary of the Tons river,
which in turn drains into the river Yamuna. This rises from the
Dhauladhar range ( South facing slopes ) near the border of UP
and Himachal Pradesh and the extreme North-Eastern of Shimla
district. The main stream is fed by the Chandra Nahan glacier
and springs originating from underground waters. It joins the
Tons river at the base of the Chakrata massif near the border
of Uttar Pradesh and Himachal Pradesh. |
| Patsari River : |

river and joins it at Kalsi in the North-Western part of Dehradun
valley ( approximately 48 km. away from Dehradun ). It rises
as the following two feeder streams - the Supin river rises from
in the Northern part of the Tons catchment near the Himachal
Pradesh and Uttar Pradesh border and the Rupin river rises from
a glacier at the head of the famous Har-Ki-Dun valley in the
North-North Eastern part of the Tons catchment. These two feeder
streams merge near the mountain hamlet of Naitwar and the channel
downstream of Naitwar is known as Tons river. The river flows
along a V shaped valley. A number of settlements have come up
along the Tons river such as Tuni, Naitwar and Menus. |
