The Bhaga valley formed from Suraj Tal up to Tandi is a narrow gorge, and is devoid of any vegetation up to Darcha. Thereafter it widens up to its confluence with Chandra River at Tandi with terraces between Darcha and Tandi which are under cultivation in the lower slopes, with the middle slopes having grasslands. Plantation of trees and shrubs to meet fuel wood and fodder requirements has been done on the hill slopes.
Physiology of Suraj Tal
Situated in the Upper Himalayan Zone or the high latitudinal part of the Himalayas, the Suraj Tal Lake is fed from glaciers and torrential streams originating from the Baralacha Pass. The region has sparse population with the climate being akin to polar conditions. There is scanty snowfall in this region, though it is reported to be spread all year round. Rainfall precipitation is rare in the region. Snow precipitation from snow storms is reported to be less than 20 cm of snow in nearly 50% of the storms, even though one observatory in the region has reported 80 cm of snow fall.
The lakes geology is represented by the Baralacha Pass, which is reported to be an early rifting event on the northern Indian passive margin and that the basalts which are emplaced along the trans-tensional faults indicate that.
