The water balance of a mountain lake is given as:
E
=
P
+
Q
i
-
Q
o
+ Δ
S/
Δ
t
E
= monthly evaporation from the lake
P
= monthly precipitation on the lake
Q
i
= the monthly water inflow to the lake
Q
o
= the monthly water outflow from the lake
Δ
S/
Δ
t
= the monthly change in water storage in the lake; Δ
S
is positive if the storage increases; Δ
S
is negative if the storage decreases.
All variable values are in mm month
