The
main
purpose
of
the
dam
is
hydroelectricity
with
some
irrigation
in
neighboring
areas.
Today
the
Koyna
Hydroelectric
Project
is
the
largest
completed
hydroelectric
power
plant
in
India[2]
having
a
total
installed
capacity
of
1,960
MW.
Due
to
its
electricity
generating
potential,
Koyna
river
is
considered
as
the
'life
line
of
Maharashtra'.[3]
The
spillway
of
the
dam
is
located
at
the
center.
It
has
6
radial
gates.
The
dam
plays
a
vital
role
of
flood
controlling
in
monsoon
season.
The
catchment
area
dams
the
Koyna
river
and
forms
the
Shivasagar
Lake
which
is
approximately
50
km
(31
mi)
in
length.
It
is
one
of
the
largest
civil
engineering
projects
commissioned
after
Indian
independence.
The
Koyna
hydro-electric
project
is
run
by
the
Maharashtra
State
Electricity
Board.[citation

The
dam
has
withstood
many
earthquakes
in
the
recent
past,
including
the
devastating
1967
Koynanagar
earthquake,
resulting
in
the
dam
developing
some
cracks.
After
the
disaster
grouting
of
the
cracks
was
done.
Also
internal
holes
were
drilled
to
relieve
the
hydrostatic
pressures
in
the
body
of
the
dam.
Indian
scientific
establishment
has
formulated
an
ambitious
project
to
drill
a
deep
borehole
in
the
region
and
intensely
study
the
earthquake
activity.
This
would
help
in
better
understanding
and
possible
forecast
of
earthquakes.
The
proposal
is
to
drill
up
to
7
km
and
study
the
physical,
geological
and
chemical
processes
and
properties
of
the
reservoir
triggered
earthquake
zone
in
real
time.
It
would
be
an
international
project
to
be
led
by
Indian
scientists.[4]
