Resumen:
Climate
data
and
satellite
information
are
important
tools
to
understand
the
dynamics
of
water
bodies.
The
evolution
of
Muster
and
Colhué
Huapí
lakes
in
the
period
1998-‐
2013
was
studied.
The
former
is
a
deep
oligotrophic
lake
and
the
latter
is
a
large
shallow
lake,
both
are
interconnected
by
the
Senguer
river.
The
aim
of
this
study
was
to
compare
the
changes
occurred
in
the
area
of
those
lakes
based
on
satellite
images
information
(LANDSAT
5,7
and
8)
and
correlate
them
with
results
from
climate
data
analysis
(rainfall
and
temperature)
records
provided
by
the
Subsecretaría
de
Recursos
Hídricos
de
la
Nación
(SSRH).
Within
the
period
1998-‐2013,
dry,
wet
and
normal
years
were
identified.
Also,
the
occurrence
of
extreme
events
was
studied
by
Palmer
Index
analysis.
The
results
showed
that
in
the
study
period,
lakes
changed
from
dry
to
wet
condition
every
8
years.
In
2000
Coluhé
Huapí
lake
area
was
283
km2
and
increased
until
2008,
when
it
reached
its
largest
extension
(761
km2)
to
decrease
to
337
km2
in
2013.
Local
climate
data
and
Palmer
Index
results
did
not
show
an
acceptable
correlation
with
lakes
area
variations.
This
could
be
explained
as
lakes
are
watershed
base
level
so
the
basin
processes
could
have
more
influence
over
the
lakes
area
than
local
climate
conditions.
Also
anthropic
activities
in
the
area
are
significant
and
they
will
be
considered
in
following
studies.
