The
Deduru
Oya
Dam
is
an
embankment
dam
built
across
the
Deduru
River
in
Kurunegala
District
of
Sri
Lanka.
Built
in
2014,
the
primary
purpose
of
the
dam
is
to
retain
approximately
a
billion
cubic
metres
of
water
for
irrigation
purposes,
which
would
otherwise
flow
out
to
sea.
Site
studies
of
the
dam
began
in
2006
and
construction
started
in
2008.
It
was
ceremonially
completed
in
2014,
with
the
presence
of
the
then
President
Mahinda
Rajapaksa.
Site
studies
and
design
of
the
dam
was
done
by
engineers
from
the
Ministry
of
Irrigation.
The
dam,
which
measures
approximately
2,400
m
(7,900
ft)
wide,
creates
the
Deduru
Oya
Reservoir,
which
has
a
capacity
of
75,000,000
m3
(2.6×109
cu
ft).
Water
from
the
reservoir
is
used
to
irrigate
approximately
11,000
hectares
(27,000
acres)
of
farmland,
while
also
powering
a
1.5
megawatt
hydroelectric
power
station,
operated
by
the
Ministry
of
Power
and
Energy.
In
addition
to
the
eight
sluice
gates,
water
from
the
reservoir
is
channelled
from
the
reservoir
(for
irrigation)
via
three
canals,
namely
the
Left
Canal,
Central
Canal,
and
the
South
Canal.
The
South
Canal
is
a
trans-basin
concrete
canal
measuring
33
km
(21
mi),
channelling
water
from
the
Deduru
Oya
Reservoir
to
the
Inginimitiya
Reservoir
at
a
flow
rate
of
300
cu
ft/s
(8.5
m3/s).
