Indus,
July
2003.

Indus
is
continuing
to
develop
an
Internet­
based
analysis
tool
known
as
the
Watershed
Assessment,
Tracking,
and
Environmental
Results
System
(
WATERS),
which
integrates
and
indexes
PCS
and
303(
d)
data
to
a
digital
map
of
waterbodies
throughout
the
conterminous
United
States
known
as
the
National
Hydrography
Dataset
(
NHD).
The
WATERS
303(
d)
database
contains
a
combination
of
information
from
the
1998
and
2000
state
reporting
cycles.
Most
information,
however,
is
from
1998.

WATERS
was
used
to
prepare
the
impaired
waters
analyses
summarized
in
the
above
referenced
report,
as
well
as
to
produce
all
of
the
other
impaired
waters
analyses
entered
into
the
304(
m)
docket.

WATERS
