7. The Mountainous Regime of the
Kameng River Basin
The Himalayan drainage area of Kameng and its
tributaries are grouped into three zones.
The Northern zone:-The precipitation (rainfall as well as
snowfall) in this zone is about 300 cm and the climate is
Temperate to Alpine. A few unnamed glaciers also exist in
this zone as evident from satellite imagery on the extreme
north of the basin in the vicinity of the Kangto massif

8. The middle zone:-About 60 km wide attaining height
up to 4,877 m. Snow peaks are common. Rainfall
reaches 300 cm to 400 cm.
The outer zone or southern zone:-The hilly area about
26 km broad, the general height being about 2,400 m
though it may attain 3,040 m. The climate is humid
Tropical and Temperate with rainfall exceeding 300 cm.

9. VEGETATION
The natural vegetation of the Kameng Drainage Basin
can be divided in three distinct belts governed by the
altitude-Tropical up to 1800 m, Temperate 1800 m to
3500 m, and Alpine between 3500 m to 5500 m.
The forest type ranges from tropical evergreen in the
foothills through temperate evergreen in the middle
ranges to the conifers in the higher elevations.
Paddy is the main staple crop grown during the Kharif
season
