The water source comes either from the Laba river or its underflow (30% of the
long-time average annual flow).
The source of the Laba basin rivers are of a mixed type. Surface flow of the plain
and piedmont parts of the basin is formed by melting snow, rainfall, and
groundwater with a higher rainfall water share for piedmont rivers and a higher
snow melt share for plain rivers. Glacier water is of a significant role for the
water flow of the mountain and high mountain rivers originating from glaciers at
1500 m and higher which makes up for more than 30 % of the annual water flow.
The sources of the Bolshaya Laba are the glaciers of the Abinka Mountain. The
Malaya Laba originates from the snow top of the Ashikha Mountain and Pseashko
glacier. Total area of glaciers feeding these rivers is 15 km2. The piedmont part of
the basin begins with the Laba reaching the wide valley at Kaladzhinskaya
settlement.
