ENVIRONMENTAL FLOW
Operation of the Talong Londa HEP has been planned for peaking and non-peaking hour power
generation during high discharge period from June to November and only peaking hour power
generation during low discharge period i.e. December to May.
As the river is flat, the discharge of 5.275 cumec (10% of lean season average) is giving depth of more
than 82 cm at all the cross sections. The flow velocity is in range of 0.42 to 1.457 cumec. The pre-
16
Executive Summary
project average of 52 cumec during lean period and over 80 cumec during May and December, the
release of 5.275 cumec for 950m river stretch till the confluence of Pachi River is sufficient.
Therefore, a minimum of 5.275 cumec (10% of average lean season discharge in 90% DY) release is
recommended during entire non peaking period from December to May. This flow will be released
from dam during non-peaking hours when no machine is running to ensure water availability in the
downstream stretch. An additional dam toe turbine can also be considered for non-peaking hour
power generation during lean period to utilize the flow.
The above study fulfills the requirement of ToR, for criteria of minimum river depth of 0.5 m in
downstream of dam for aquatic life.
