Background
It
is
highly
recommended
that
all
sites
featured
in
this
assessment
have
a
dredge
management
plan
created,
taking
into
account
breeding
Piping
Plover
(PIPL)
and
Least
Tern
(LETE)
populations.
The
following
sites
were
visited
and
evaluated
using
2013
breeding
season
(April
1
–
August
15)
photos,
Google
Earth
images
from
3/6/12
(images
exist
from
11/3/12
but
are
poor
quality),
and
on-‐the-‐ground
observations
to
determine
the
following
factors:
• Amount
of
sandy
beach
and
suitable
nesting
habitat
above
the
high
tide
mark.
• Area
of
foraging
habitat
for
transient
and
winter
shorebirds.
• Proximity
to
homes
and/or
recreational
areas,
e.g.
heavy
watercraft
use,
beach
bathing,
fishing,
dog
walking.
• Presence
or
absence
of
nesting
and/or
foraging
PIPL
and
LETE
in
past
surveys.

Brushes
Creek
Due
to
presence
of
multiple
groins
and
bulkheads
at
this
site
(see
images
below),
PIPL
and
LETE
did
not
nest
in
2013
and
most
likely
will
not
in
the
near
future.
PIPL
were
not
observed
during
site
visits
but
LETE
were
occasionally
observed
foraging
in
the
area,
particularly
on
the
eastern
beachside
of
the
creek,
where
there
is
no
bulkhead
and
more
beach
habitat.
A
new
bulkhead
was
installed
at
the
property
immediately
adjacent
to
the
channel
on
the
east.
The
three
homes
to
its
east
either
have
no
bulkhead
protection
or
have
not
repaired
damage
from
past
storms
(Fig.
2-‐4).
Recommendation
–
This
is
an
active
boat
channel
and
has
partially
filled-‐in
on
the
eastern
side
(Fig.
1)
compared
to
the
2012
visit.
However,
the
flow
remains
steady.
Dredge
material
should
be
placed
east
of
the
inlet,
thereby
increasing
the
beach
behind
the
rock
jetty
(Fig.
3).

Cedar
Beach
Creek
Of
all
the
sites
visited,
this
one
continues
to
function
very
closely
to
a
natural
state.
On
a
visit
in
June,
the
channel
at
low
tide
was
quite
deep
(Fig.
5).
As
noted
in
the
2012
report,
this
Cedar
Beach
Creek
should
be
a
top
priority
for
dredging,
as
both
PIPL
and
LETE
utilize
the
site
for
foraging
and
nesting
(both
nested
in
2013).
In
addition,
upwards
of
14
other
shorebird
species
were
noted
when
visiting
this
site,
including
Roseate
Tern
(NYS
Endangered).
Of
note,
a
PIPL
pair
nested
successfully
in
habitat
created
during
last
year’s
winter
storms.
This
area
is
roughly
200
yards
east
of
the
channel
and
not
affected
by
future
dredging.
Recommendation
–
if
dredging
occurs
in
2014,
continue
placing
dredge
material
to
the
east
of
the
inlet
(Fig.
6)
to
maintain
excellent
nesting
habitat
for
PIPL
and
LETE.
Fig.

Fig.

Corey
Creek
While
two
PIPL
pairs
were
noted
in
2013,
neither
was
found
to
have
nested
successfully
(LETE
did
not
attempt
to
nest).
As
indicated
in
the
past,
predation
(e.g.
crows,
fox,
gulls)
and
human
disturbance
(e.g.
beach
bathers,
boaters,
fisherman)
are
factors
at
this
site,
particularly
on
the
western
side
(Fig.
7)
adjacent
to
the
Town
beach.
The
east
side
of
the
creek
(Fig.
8)
has
been
a
popular
site
for
PIPL
in
the
past,
but
the
topography
of
the
spit
has
become
flattened,
especially
within
the
past
year
due
to
the
numerous
storms.
Recommendation
–
dredge
material
should
be
placed
east
of
the
channel
(Fig.
8)
to
increase
beach-‐nesting
habitat
above
high
tide.
Currently,
the
area
floods
at
extreme
high
tide.
Fig.

Fig.

Deep
Hole
Creek
Multiple
groins
and
bulkheads
hamper
nesting
by
PIPL
and
LETE
at
this
site.
One
of
the
only
areas
to
nest
is
along
a
sandy
spit
directly
off
Marratooka
Point
(Fig.
9).
As
noted
in
2012,
it
is
most
likely
they
will
not
breed
here
in
the
near
future.
In
2013,
PIPL
were
not
observed
during
site
visits
but
LETE
were
occasionally
observed
foraging
in
the
area,
particularly
offshore
in
Peconic
Bay.
Recommendation
–
extensive
scouring
was
noted
east
of
the
channel
and
adjacent
bulkhead
(Fig.
10).
Placing
dredge
material
along
this
expanse
would
provide
a
more
natural
incline
along
the
shore,
resulting
in
potential
beach-‐nesting
habitat.
Fig.

Goldsmith
Inlet
This
site
is
by
far
the
most
dynamic
of
the
16
visited.
For
the
fifth
season,
a
pair
of
PIPL
nested
on
old
dredge
material
adjacent
to
the
Town’s
parking
area
(Fig.
11).
Similar
to
2010,
2011
and
2012,
no
LETE
were
noted
as
nesting,
however
up
to
a
half-‐dozen
were
seen
foraging
and
resting
on
the
beach
intermittingly.
This
season,
the
channel
into
the
pond
maintained
a
broad
shoal,
nearly
preventing
a
proper
flush
to
enter
and
leave
through
the
inlet
(Figs.
12
&
13).
Recommendation
–
as
noted
in
2012,
enhancing
the
current
PIPL
nest
location
with
dredge
material
to
the
north
(depressed
area
west
of
jetty)
will
ensure
future
PIPL
nesting
habitat.
Past
dredging
activities
likely
contributed
to
a
successful
PIPL
nest
east
of
the
Inlet,
where
on
Aug.
10
John
Sep
noted
2
not
quite
fledged
PIPL
chicks
adjacent
to
county
park
property.
The
Town’s
placement
of
dredge
material
along
this
stretch
of
the
Long
Island
Sound
has
greatly
improved
beach-‐nesting
habitat.

Goose
Creek
Quite
evident
this
year
was
the
expansive
channel
extending
from
North
Bayview
Road
Bridge
to
Southold
Harbor
(Fig.
14).
As
noted
in
2012,
this
site
possesses
suitable
nesting
habitat
(Fig.
15)
but
due
to
its
popularity
as
a
beach
bathing
location
and
an
area
where
boaters
come
ashore,
it
did
not
feature
any
PIPL
or
LETE
on
monitoring
visits
this
year.
Recommendation
–
Based
on
field
observations
and
the
importance
for
navigation
at
this
site,
material
should
be
placed
west
of
the
Southold
Yacht
Club.

What
a
difference
a
year
makes.
In
2012,
the
channel
extending
from
the
marsh
into
the
bay
was
heavy
with
sediment
(see
Google
Earth
image
below).
As
noted
then,
the
site
had
appeared
as
if
it
had
not
been
dredged
in
many
years.
Upon
visiting
in
2013,
the
shoal
that
had
formed
at
the
mouth
of
the
inlet
had
been
greatly
reduced
(Fig.
17)
and
the
entire
channel
was
quite
easy
to
navigate.
However,
the
beach
to
the
east
of
the
channel
was
heavily
eroded,
likely
the
result
of
the
adjacent
bulkheads
along
the
Halls
Creek
channel.
Recommendation
–
While
a
few
homeowners
along
Halls
Creek
have
boats
and
utilize
the
channel
for
access
to
the
bay,
consistent
dredging
will
greatly
improve
the
ecological
integrity
of
the
saltmarsh.
Similar
to
the
recommendation
for
Deep
Hole
Creek,
placement
of
dredge
material
along
this
expanse
would
provide
a
more
natural
incline
along
the
shore,
resulting
in
potential
beach-‐nesting
habitat.

James
Creek
As
noted
in
2012,
the
presence
of
multiple
groins
and
bulkheads
(see
Google
Earth
image
below;
Fig.
19)
at
this
site
do
not
provide
adequate
nesting
habitat
for
PIPL
and
LETE.
While
LETE
were
seen
foraging
on
site
visits,
PIPL
were
not.
The
creek
is
a
very
active
waterway
(Fig.
20),
as
a
private
marina
is
located
roughly
100
yards
from
the
channel
opening
to
the
bay.
Recommendation
–
none
at
this
time,
as
it
seems
unlikely
PIPL
and
LETE
will
nest
at
this
location
in
the
immediate
future.
Fig.

Little
Creek
Remaining
consistent
with
prior
years,
this
site
continues
to
be
one
of
the
most
productive
for
breeding
PIPL.
As
in
2012,
a
pair
of
PIPL
nested
north
of
the
creek
channel
in
an
area
(Fig.
21)
that
was
inundated
by
sand
from
last
year’s
winter
storms.
While
LETE
did
not
nest
at
the
site
typically
8
or
more
were
loafing
on
a
sandbar
arc
in
the
channel
(Fig.
22).
Recommendation
–
a
more
coordinated
approach
to
dredging
at
this
site
with
Suffolk
County,
Town
of
Southold,
and
the
New
Suffolk-‐Cutchogue
Park
District
needs
to
happen
to
ensure
better
communication
and
natural
resource
planning
goals
are
met.
As
noted
in
2012,
and
due
to
the
extensive
work
conducted
this
year
to
address
erosion
issues
south
of
the
creek
channel,
it’s
advised
to
place
dredge
material
on
Town
land
to
the
north.
Fig.

Fig.

Mud
Creek
Limited
nesting
habitat
and
the
high
degree
of
human
disturbance
due
to
recreational
pursuits
–
mostly
boating
(Fig.
23)
and
swimming
–
likely
led
to
an
absence
of
both
PIPL
and
LETE
at
this
site.
As
in
previous
years,
both
species
were
seen
on
occasion,
but
neither
remained
for
any
duration.
Recommendation
–
the
western
portion
of
beach
adjacent
to
the
channel
featured
moderate
erosion
(Fig.
24)
during
the
breeding
season.
It
was
unclear
if
this
was
due
to
a
past
storm
event(s)
or
if
dredge
material
had
been
placed
there
in
January.
It
seemed
like
the
latter,
as
the
section
above
high
tide
was
devoid
of
vegetation.
It
is
recommended
that
future
dredge
material
be
placed
to
the
east
of
the
channel
to
increase
potential
nesting
habitat.
Fig.

Richmond
Creek
At
times
it
can
be
difficult
to
differentiate
between
PIPLs
at
this
site
and
Corey
Creek,
as
the
latter
is
located
roughly
200
yards
to
the
east.
While
at
least
two
sets
of
PIPL
pairs
attempted
to
nest
at
Corey
Creek,
no
PIPL
attempted
to
nest
at
this
site.
LETE
were
noted
on
nearly
every
visit
after
June
1
through
August,
but
none
attempted
to
nest.
Recommendation
–
the
channel
appeared
deep
and
had
a
steady
flow
on
each
visit
(Fig.
25).
As
in
the
past,
dredge
material
should
be
removed
and
relocated
to
the
east
of
the
channel,
South
Harbor
Beach
(Fig.
26).
Fig.

School
House
Creek
As
noted
in
2012,
the
presence
of
docks
and
significant
bulkhead
at
this
site
(see
Google
Earth
image;
Fig.
27),
virtually
prohibit
PIPL
and
LETE
from
nesting
at
this
location.
Neither
species
was
observed
during
site
visits
this
year.
A
significant
amount
of
boat
traffic
is
present
in
this
small
area,
also
contributing
to
an
insufficient
breeding
area.
Recommendation
–
none
at
this
time,
as
it
seems
unlikely
PIPL
and
LETE
will
nest
at
this
location
in
the
immediate
future.
Fig.

Fig.

Sterling
Harbor
As
noted
in
2012,
this
site
no
longer
contains
suitable
nesting
and
very
little
if
any
foraging
habitat
(Figs.
29-‐31),
especially
when
compared
to
the
nearby
Gull
Pond
West
site
–
one
of
the
three
most
productive
beach-‐nesting
sites
in
Southold
–
about
400
yards
to
the
south.
In
2013,
no
PIPL
or
LETE
were
seen
on
site
visits.
In
addition,
one
of
the
largest
marinas
on
the
North
Fork
is
located
at
this
site.
It
was
noted
on
one
visit
that
intense
boat
traffic
caused
waking
that
regularly
flooded
the
peninsula
(Fig.
29)
above
the
high
tide
margin.
Recommendation
–
none
at
this
time,
as
it
seems
unlikely
PIPL
and
LETE
will
nest
at
this
location
in
the
immediate
future.

Town
Creek
As
noted
in
2012,
this
area
features
an
extensive
network
of
bulkheads
and
docks
within
a
very
popular
waterway
(see
Google
Earth
image;
Fig.
32).
Due
to
this,
as
well
as
the
presence
of
a
popular
public
beach
at
Founder’s
Landing
(Fig.
33),
there
is
not
any
viable
nesting
and
minimal
foraging
areas.
Therefore,
it
should
not
be
surprising
that
no
PIPL
or
LETE
were
seen
on
site
visits.
Recommendation
–
none
at
this
time.
Fig.

Fig.

West
Creek
Similar
to
other
bayside
locations,
this
site
features
multiple
groins
(Fig.
34)
and
shore-‐
harden
areas,
in
particular
the
extensive
bulkhead
off
Kimogener
Point
(Fig.
35).
Due
to
this,
neither
species
was
seen
attempting
to
nest,
however
LETE
were
noted
foraging
in
the
bay
on
nearly
all
visits
from
June
through
August.
Of
special
interest,
the
peninsula
(see
Google
Earth
image
below)
that
had
formed
within
the
West
Creek
channel
was
removed
due
to
mid-‐winter
dredging
activities.
While
this
did
not
improve
nesting
habitat
for
PIPL
and
LETE,
it
did
improve
ecological
flow
for
the
saltmarsh.
Recommendation
–
the
beach
to
the
east
of
the
Kimogener
Point
bulkhead
continues
to
erode
(Fig.
36).
Future
dredging
efforts
should
be
made
to
place
dredge
material
in
this
section,
while
gradually
grading
the
topography
to
create
beach-‐nesting
habitat.

Wickham
Creek
The
southern
beach
exposure
along
this
creek
provides
great
foraging
and
potential
breeding
habitat
for
PIPL
and
LETE
(Fig.
37).
While
both
species
were
noted
on
site
visits,
as
well
as
other
shorebirds
and
Common
Terns,
neither
nested
once
again.
Predation
by
fox,
as
tracks
were
seen
in
2013,
could
be
deterring
beach-‐nesting
birds
from
remaining
through
the
season.
From
field
observations
it
appeared
the
creek
has
been
dredged
within
the
past
few
years.
Recommendation
–
future
dredge
material
should
be
placed
to
the
south
of
the
creek,
likely
what
has
been
done
in
the
past.
