ABSTRACT 

Surface  cuirents  were  investigated  in  central  and  southern 
Lake  Michigan  in  1954,  and  in  central  and  northern  Lake  Michigan 
in  1955.    Drift  bottles,  drift  envelopes,  and  plastic  tubes  were 
released  in  1954,  whereas  drift  bottles  only  were  used  in  1955. 

Currents  were  highly  variable  in  both  years  and  in  all  areas  of 
Lake  Michigan.    The  general  direction  of  drift  was  from  west  to 
east;  cuirents  were  predominately  north-bound  along  the  eastern  shore. 
No  jvevailing  current  was  detected  along  the  western  shore.

SURFACE    CURRENTS    IN    LAKE    MICHIGAN. 
1954   AND    1955 


INTRODUCTION 

Before  1954  the  only  publication  describing  the 
major  surf  ace -current  circulation  in  Lake  Michigan 
was  by  Harrington  (1895).    Subsequent  investigations 
were  either  local  or  of  limited  scope  (Crohurst  and  Vel  - 
dee  1927;  Deason  1932)  oiwere  discussions  of  Harring- 
ton's conclusions  (Townsend  1916)  and  statements 
as  to  the  inadvisabiUty  of  studying  the  lake  currents 
as  a  whole (Judson  1909).   The  recent  analysis  of  syn- 
optic surveys  conducted  in  Lake  Michigan  in  1955 
not  only  contributed  to  knowledge  of  the  lake  cur- 
rents (Ayers  et  al.  1958)  but  also  inttoduced  oceano- 
graphic  procedures  and  interpretations  into  the  study 
of  the  circulation  of  the  lake. 

The  present  study  of  the  circulation  of  Lake  Mich  - 
igan  was  part  of  the  1954-1955  fishery -Umnological 
survey  conducted  by  the  M/V  Cisco  of  the  U.  S.  Bureau 
of  Commercial  Fisheries,  Fish  and  WildUfe  Service. 
The  1954  work  was  confined  to  the  central  and  south- 
em  part  of  the  lake  and  the  1955  survey  was  conducted 
in  the  central  and  northern  area  (fig.  1).  Smith(1957) 
who  commuted  briefly  concerning  the  use  of  drift 
units  and  the  determination  of  lake  currents  stated  from 
preliminary  analyses  of  the  datathat  the  major  surface- 
current  struaureofLake  Michigan  can  change  over  a 
3 -week  period.  This  repOTt  completes  the  analysis  of 
returns  of  all  drift  units  released  in  Lake  Michigan  in 
1954  and  1955. 

John  Ayen  of  the  Great  Lakes  Research  Institute 
made  suggestions  in  the  jweparation  of  the  manuscript; 
Anthony  PerUck  and  Robert  Wetzel  drafted  the  figures; 
and  the  U.  S.  Coast  Guard  made  wind  records  available. 

GENERAL  FEATURES  OF  LAKE  MICHIGAN 


Lake  Michigan,  the  third  largest  of  the  Great  Lakes 
(22. 400  square  miles)  lies  wholly  within  the  United 
States.  The  maximum  depth  is  924  feet,  the  mean  is 
276  feet,  and  the  channel  depth  of  the  Straits  of  Mack- 
inac is  about  100  feet  (Emery  1951).   The  long  axis 
of  the  lake,  approximately  325  miles.  Ues  in  a  UOTth- 
northeast  to  south -southwest  direction.  Excluding  bays 
and  Inlets,  the  maximum  east -west  width  of  85  miles 
is  about  43-00  •  north  latitude  approximately  on  a  line 
from  Grand  Haven.  Michigan,  to  Milwaukee,  Wisc<msin 


CURRENT -GENERATING  AGENTS  AND 
MODIFYING  FACTORS 

The  circulation  of  Lake  Michigan  is  an  inte- 
gration of  the  effects  of  generating  agents  (wind  and 
density  distribution)  modified  by  morphology  of  the 
lake,  the  Cotiolis  force,  and  hydrauUc  currents. 

Wind 

The  wind  creates  currents  in  two  ways.    First, 
the  most  direct  and  obvious  effect  is  the  formation  of 
shallow  wind  drift;  second,   the  transport  of  ir«ex  by 
the  wind  stress  alters  the  density  distributi<Hi  and,  c«mi- 
sequently,  the  currents.    Movements  of  water  in  Lake 
Michigan  in  the  Calumet  district  of  Illinois  and  Indiana 
are  considered  to  be  wind  drifts  (Crohurst  and  Veldee 
1927).    Similarly,  the  prevailing  westerly  winds  over 
Lake  Michigan  have  been  considered  the  cause  of  the 
general  west-to-east  drift  of  bottles  across  the  lake 
(Harrington  1895;  Deason  1932).    For  the  particular 
years  and  area  in  which  these  investigators  worked,  it 
is  possible  that  westerly  winds  did  prevail.  Recent  evi- 
dence indicates,  however,  that  in  southern  Lake  Mich- 
igan from  May  through  August  winds  tend  to  be  variable 
and  not  from  any  one  prevailing  direction  (Cooperman, 
et^.  1959), 

Density 

Ayers  et  ^.  (1956,  1958)  have  demonstrated  that 
density  currents  are  common  in  the  Great  Lakes.  They 
have  been  careful  to  point  out  that  extreme  caution 
must  be  used  in  determining circulati<m  from  the  distri- 
bution of  density  because  of  the  ease  with  which  the 
cfrculatlon  can  be  changed  by  wind  stress.   At  times  it 
is  impossible  to  teU  whether  the  distribution  of  density 
causes  the  cnnents,  or  the  currents  cause  the  distribution 
of  density  (Sverdrup,  Johnscm,  and  Fleming  1942). 


Morphology 

A  most  important  but  little  nderstood  factor  in 
the  circulation  of  Lake  Michigan  is  morphology.  The 
Great  Lakes*  basins  acquired  their  major  topographic 
features  in  pre -Pleistocene  time  by  subaerial  erosion 
and  stream  development  actingon  a  variety  of  bedrock 
formations  (Hough  1953,  1958).  The  level  of  Lake  Mich-

igan  has  varied  since  the  appearance  of  the  first  pre- 
decessor lake  24,  000  years  ago  (Hough   1953,    1958) 
from  640  feet  above  sea  level  in  the  Glenwood  stage 
13, 000  years  ago  to  230  feet  above  sea  level  in  the 
Chippewa  stage  5,  000  years  ago  (Zumberge  and 
Potz[g]erl956).  For  the  last  90  years  the  mean  level 
has  been  580.  6  feet. 

The  bottom  topography  formed  by  these  glacial 
events  has  been  described  in  detail  by  Emery  (1951). 
The  lake  can,  in  general, be  divided  into  a  southern 
basin  of  gentle  bottom  gradients  and  a  northern  basin 
with  considerable  fjord -like  top)ography. 

AccOTding  to  Sverdrup,   Johnson,    and  Fleming 
(1942),  Ekman  has  examined  the  influence  of  bottom 
topography  on  ocean  currents.    He  concluded  that  in 
middle  and  high  latitudes  currents  tend  to  follow  bot- 
tom contours.    He  found  also  that  a  current  is  deflect- 
ed cum  sole  when  entering  shallow  water  and  contra 
solem  when  entering  deeper  water.  If  Lake  Michigan 
behaves  as  an  ocean,   the  bottom  topography  would 
effect  major  modification  of  the  circulation,  espe- 
cially in  view  of  the  extremely  irregular  topography 
in  the  northern  basin. 

Near  coast  lines,  secondary  effects  of  the  wind 
become  important  through  alteration  of  density  which 
in  turn  cause  littoral  currents  (Sverdrup,  Johnson,  and 
Fleming  1942).  In  Lake  Michigan  where  the  ratio  of 
length  to  width  is  approximately  5:1,  the  littcxal  cur- 
rents become  increasingly  important  in  the  general 
circulation  of  the  lake. 

Another  effect  of  the  confining  nature  of  the  coast 
line  is  the  actual  piling  up  of  water  in  some  areas 
and  the  removal  of  water  in  others  when  a  strong  wind 
blows  for  a  prolonged  period  from  one  direction.    Ap- 
preciable slopes  ofthe  water  surface,  which  must  be  ad- 
justed eventually,  can  be  inferred  in  Lake  Michigan 
from  water-level  reccwds. 

Cofiolis  Force 

The  effects  of  the  Corlolis  force  upon  currents 
were  described  in  detail  by  Sverdrup.  Johnson,  and 
Fleming  (1942).  If  the  water  surface  is  unlimited  and 
the  water  is  very  deep  in  comparison  with  the  depth 
of  frictional  resistance  (i.  e. ,  the  depth  at  which  mix  - 
ing  due  to  wind  is  negligible)  a  deflection  of  45°  cum 


sole  of  the  surface  current  from  the  generating  wind 
direction  is  theoretically  possible  according  to  Ekman. 
Deflections  of  this  magnitude  were  actually  observed 
by  Forch(1909),  Galle  (1910),  and  others.    Ekman 
proposed  that  in  shallow  water  the  deflection  would  be 
less,  and  it  has  been  found  so  by  Wilting  (1909)  in 
depths  of  9  to  65  meters  and  by  Mandelbaum  (1955) 
in  less  than  20  meters  of  water. 

Studies  of  the  Coriolls  fcsce  in  water  movements 
of  the  Great  Lakes  are  lacking.    Because  depths  far 
greater  than  the  depth  of  frictional  resistance  exist  in 
Lake  Michigan,  and  because  of  the  relatively  large 
surface  area,  it  is  suspected  that  Coriolis  deflection 
exists  as  has  been  empirically  demonstrated  by  Ayers 
et  aL  (1958). 

Hydraulic  Currents 

Hydraulic  currents  are  caused  by  the  inflow  and 
outflow  of  water  from  a  basin.    Maximum  inflow  into 
Lake  Michigan  from  rivers  and  streams  occurs  gener- 
ally in  the  spring  and  is  minimum  in  the  fall.    Outflow 
is  limited  to  the  Straits  of  Mackinac  (55,  000  cfs.  -- 
Powers  and  Ayersl' )  and  the  Chicago  drainage  system 
(approximately  3,  000  cfs.  --U.  S.  Corps  of  Engineers 
1957).  It  appears  in  general  that  effects  of  the  hydraulic 
currents  in  Lake  Michigan  are  mostly  local,  occurring 
at  the  mouths  of  rivers  and  in  the  vicinity  ofthe  outlets. 

TYPES  OF  DRIFT  UNITS 

Three  types  of  units  were  used  in  1954:  drift  bottles 
with  metal  drags  (fig.  2A);  plastic  tubes  with  metal 
drags  (fig.  2B);  drift  envelopes  similar  to  those  de- 
scribed by  Olson  (1951)  (fig.  2C).    Two  types  were 
released  in  1955--drift  bottles  with  metal  dra^  or 
with  sand  ballast  (fig.  2D). 

Drift  Bottles 

The  bottles  were  4-ounce,   Boston-round  (4  1/2 
inches  long,  1  9/10 -inch  diameter)  stoppered  with 
corks,  sealed  with  beeswax,  and  capped.  Metal  drags 
caused  the  bottles  to  sink  until  only  about  1/2  inch  was 
exposed.  These  bottles  and  drags  were  similar  to  those 
used  in  Lake  Huron  and  Saginaw  Bay  (Johnson  1958).

During  1954  and  until  August  19  in  1955  the 
drag  was  suspended  3  feet  below  the  bottles  by  a 
soft  iron  wire.    Thereafter,  the  drag  was  susp>ended 
1  foot  below  the  bottles  to  lessen  resistance  to  wash- 
ing ashore.    Observations  of  dye  patches  revealed 
that  the  movement  of  the  bottles  was  not  changed  by 
the  shortening  of  the  drag  (Smith  1956).    Many  of 
the  bottles  released  prior  to  June  5,  1955,  lost  their 
drags.    Apparently  these  losses  were  caused  by  re  - 
peated  bending  of  the  iron  suspension  wire  to  the 
point  of  breaking  as  the  bottle  was  moved  by  waves. 
Introduction  of  a  brass  ring  in  the  connection  at  the 
neck  ofthe  bottle  greatly  reduced  but  did  not  end  the 
loss  of  drags  (Smith  1956).    Losses  were  reduced  fur- 
ther, however,  in  Lake  Superior  and  Lake  Erie  in 
1958  by  the  insertion  of  a  brass  ring  connecting  the 
iron  suspension  wire  to  the  drag. 


1,  080  drift  envelopes  in  central  and  southern  Lake 
Michigan  between  July  9  and  September  15,   1954 
(table  1,  fig.  1).    In  addition,  100  plastic  tubes  were 
released  July  9  on  the  Grand  Haven -Milwaukee  tran- 
sect; on  this  date,  6  each  of  the  three  types  of  units 
were  released  at  all  stations  except  the  first  out  of 
Milwaukee  at  which  4  ofeach  type  were  released.  Sub- 
sequent to  July  9,  10  drift  bottles  and  10  drift  envelopes 
were  released  at  each  station.    Units  recovered  after 
January  31,  1955,  have  not  been  included  in  the  records 
of  recovery  or  in  analyses. 

The  18  reply  cards  received  from  recovered  plas- 
tic tubes  were  mostly  from  units  released  close  to  shore. 
This  fact  suggests  that  many  of  the  plastic  tubes  re- 
leased at  stations  distant  from  shore  must  have  become 
waterlogged  and  sank. 


Each  ballasted  bottle  contained  40  grams  of 
fine  loose  sand  which  caused  the  bottle  to  sink  in  - 
to  the  water  so  that  only  about  1/2  inch  was  exposed. 

Plastic  Tubes 

The  plastic -tube  unit  consisted  of  a  cylindrical 
tube  of  cellulose  acetate,  6  1/2  inches  long  and 
1  1/4  inches  in  diameter,  into  which  was  inserted  a 
reply  card  wound  around  a  wooden  block  (fig.  2B). 
The  unit  was  sealed  with  a  square  piece  of  cellulose 
acetate  to  which  was  attached  a  metal  drag  with  a  3- 
foot  suspension  wfre.    The  unit  floated  with  approxi- 
mately 2  inches  of  the  tube  above  the  surface. 

Drift  Envelopes 

The  drift -envelope  unit  consisted  of  a  3-  by 
5 -inch  reply  card  enclosed  within  a  3  3/4-  by  6  1/4- 
inch  polyethylene  envelope  of  0. 002-inch  thickness 
(fig.  2C).  Water  did  not  adhere  to  the  plastic  enve- 
lopes at  first;  most  of  the  envelopes  floated  upon  the 
surface  film  where  they  were  under  the  direct  pro- 
pelling force  of  the  wind.    Some  time  after  release 
the  plastic  envelopes  no  longer  shed  water  and  floated 
immediately  under  the  surface  fUm  where  they  tum- 
bled end  for  end  in  a  rough  sea. 

RELEASES  AND  RECOVERIES 

Central  and  Southern  Lake  Michigan,   1954 

The  U.  S.  Bureau  of  Commercial  Fisheries  M/V 
Cisco  jreleased  1,  080  drift  bottles  with  metal  drags  and 


Percentage  recovery  of  drift  envelopes  was  low 
(table  1).    The  normal  seasonal  decline  in  rate  of  re- 
covery does  not  account  for  the  precipitous  decrease 
in  reports  of  envelopes  released  after  August  3.    It  is 
believed  that  the  plastic  envelopes  containing  the  re- 
ply cards  were  improperly  sealed  and  that  many  units 
became  waterlogged  and  sank  (Beeton,  Johnson,  and 
Smith  1959). 

The  percentage  recovery  of  drift  bottles  ranged  from 
47.  8  percent  frxthe  August  19  releases  on  the  Grand 
Haven -Milwaukee  transect  to  62.  9  percent  for  the  re- 
leases on  August  3  on  the  South  Haven -Waukegan  tran- 
sect; for  the  combined  releases  the  percentage  recovery 
was  54.4  percent  (table  1).   The  recovery  rate  was 
slightly  higher  for  units  released  in  July  and  early  Aug- 
ust than  for  those  released  in  late  August  and  September. 

Central  and  Northern  Lake  Michigan,  1955 

Between  April  26  and  November  8,   1955,  2,  000 
drift  bottles  with  dra^and  2,  000  with  sand  ballast  were 
released  (table  2,  fig.  1).    Ten  of  eachtype  were  re- 
leased at  each  station.  Units  recovered  after  January  31, 
1956,  have  not  been  included  in  the  tables  and  are  not 
mentioned  in  the  discussion. 

The  percentage  recovery  was  slightly  hi^erfor  bot- 
tles with  drags  (56.4  percent)  than  for  sand -ballasted 
bottles  (53. 0  percent).    The  difference  probably  is  not 
significant  since  more  sand -ballasted  bottles  than  bot- 
tles with  drags  were  recovered  from  6  of  the  16  cross- 
ings (table  2).

Time  and  Localities  of  Recovery 

In  both  1954  and  1955  the  recovery  rate  was 
slightly  higher  for  units  released  in  early  summer 
than  for  those  released  in  late  surnmer  and  fall 
(tables  1  and  2).    Recoveries  were  highest  on  week- 
ends and  holidays.    A  similar  time  distribution  of 
recovery  of  drift  bottles  has  been  noted  in  Saginaw 
Bay  and  Lake  Huron  (Johnson  1958). 

It  is  of  course  necessary  that  a  unit  reach  shore 
if  it  is  to  be  recovered.    The  actual  efficiency  of  re- 
covery of  beached  units  is  strongly  influenced  also 
by  the  conspicuousness  of  the  unit  once  it  has  landed 
and  the  amount  of  shore  traffic  through  the  area. 
The  latter  factor,  in  turn,    depends  upon  shore  top- 
ography and  the  density  of  the  human  population. 
In  southern  Lake  Michigan  where  the  population  is 
dense  and  sand  beaches  are  extensive,  most  areas 
are  covered  equally  well.    Here  the  uneven  distribu- 
tion of  shore  traffic  offers  a  scant  source  of  bias.  In 
northern  Lake  Michigan,  on  the  contrary,  the  exten- 
sive areas  of  sparse  population  and  the  more  rugged 
coast  line  contribute  to  lesser  and  unevenly  distrib 
uted  shore  traffic.    Records  of  recovery  are  corres- 
pondingly biased. 

High  visibility  of  units  on  shore  is  essential  to 
efficient  recovery  and  differences  in  conspicuousness 
probably  inject  a  bias  in  comparison  of  percentage 
recoveries  of  different  types  of  units.     In  early  Sep- 
tember 1954,  causes  of  differential  rates  of  recovery 
were  studied  by  inspection  of  5  miles  of  shore  line 
in  southern  Lake  Michigan,    The  following  possibil- 
ities were  revealed :  plastic  envelopes  can  be  blown 
far  back  from  the  beach  by  strong  winds  and  can  be 
covered  by  blown  sand  much  more  easily  than  tubes 
and  bottles;  the  color  of  the  cards  in  plastic  envelopes 
blends  well  with  the  flotsam  in  windrows  along  the 
beach;  on  open  sand  the  glass  bottle  with  drag  is  much 
mere  conspicuous  than  the  tube  or  envelope  because 
both  the  bottle  and  the  drag  attract  attention;  and 
glass  bottles  appear  to  be  sought  for  rifle  practice  as 
was  evidenced  by  the  great  number  of  Ixoken  bottles 
along  the  beach  and  the  everpresent  empty  cartridge 
cases. 

SURFACE  CURRENTS  IN  LAKE  MICHIGAN. 
1954  and  1955 

The  understanding  of  discussions  in  the  follow- 
ing sections  should  be  made  easier  by  a  brief  pre- 


liminary explanation  of  the  methods  of  graphical 
representation  of  the  data  (figs.  3-18).    The  fig- 
ures on  wind  direction  (figs.  3  and  8)  were  designed 
in  the  same  way  for  each  month  in  each  year  and 
the  plan  of  jxesenting  records  of  recoveries  (figs. 
4-7;  9-18)  is  the  same  for  each  transect,  regard- 
less of  type  of  drift  unit. 

The  information  on  wind  within  a  month  is 
given  in  terms  of  lines  that  show  the  percent- 
age of  the  total  time  the  wind  blew  toward  each 
of  8  sectors.    The  individual  lines  bisect  the 
sectors  000° -045°,  045°-090°,  •  •  • ;  315° -360°.  The 
percentage  of  time  is  indicated  by  the  length  of  line; 
the  radii  of  the  concentric  circles  are  in  multiples 
of  10  percent. 

The  graphs  on  recoveries  give  direction  and 
number.  The  sectors  are  the  same  as  described  for 
the  data  on  wind.  The  lengths  of  the  radiating  lines 
indicate  numbers  recovered  in  each  direction  from 
each  station  in  acccffdance  with  the  scale  at  the  bot- 
tom. Care  should  be  taken  not  to  interpret  these  lines 
as  showing  actual  locality  of  recovery.  Aline  leading 
from  an  inshore  station  dkectly  onto  the  shore  (on  oc- 
casion passing  beyond  it)  does  not  indicate  that  the  le- 
coveiies  were  made  from  the  immediately  adjacent 
beach.  Many  could  have  been,  and  indeed  were,  re- 
covered in  remote  sections  of  the  lake  not  shown  on 
the  strip  map,  but  which  would  have  been  traversed  by 
an  extension  of  the  line.    To  reach  these  points  the 
units  had  to  drift  around  intervening  headlands  or  islands. 
Release  stations  on  some  of  the  transects  do  not  lie  in 
a  straight  line.  This  irregularity  was  because  of  prob- 
lems in  navigation  in  aossing  the  lake. 

Tables  7  -22  in  the  appendix  give  the  location  of 
release  and  recovery  of  drift  units,  number  of  days  a- 
diift,  milestraveled,  and  average  drift  rate  in  miles  per 
day.  A  bottle  recovered  on  the  day  it  was  released  was 
considered  to  have  been  adrift  1/2  day.    If  it  was  re- 
covered the  day  after  release,  the  drift  period  was  one 
day.    Stations  niunbered  in  the  tables  are  located  in 
figures  4-7  and  9-18  by  counting  from  right  to  left  (east 
to  west)  with  the  exception  of  the  Manitowoc -Sturgeon 
Bay  transect  (figs.  9,  10);  on  this  transect  stations  are 
located  by  counting  from  south  to  north. 

Central  and  Southern  Lake  Michigan,  1954 

South  Hayen-Waukegan  transect.  --The  recov- 
eries from  releases  along  this  transect  illustrate  the 


considerable  difference  in  recoveries  of  identical 
drift  units  released  oa  different  days  and  bring  out 
also  the  dissimilarities  of  returns  from  different  kinds 
of  units  released  on  the  same  date.  As  wUl  be  seen 
later,  generally  similar  variability  characterized  all 
transects. 

The  most  obvious  difference  in  the  directions  of 
recovery  of  bottles  released  on  August  3  and  Septem- 
ber 15  is  from  the  four  westernmost  stations  (fig.  4). 
Recoveries  from  the  August  3  releases  at  these  stations 
with  the  exception  of  1  bottle,  were  from  the  Illinois 
(west)  shores,  whereas  all  recoveries  from  the  Septem- 
ber releases  were  from  the  Michigan  (east)  shores.  Al- 
though the  wind  was  decidedly  variable  in  August 
(fig.    3,  table  3),   for  5  days  following  the  August  3 
releases  the  Chicago  Weather  Bureau  reported  prevail- 
ing east  and  northeast  winds.    Westerly  winds  prevail- 
ed during  September  and  October  (fig.  3).  The  recov- 
ery of  most  bottles  released  at  the  remaining  stations 
from  the  Michigan  shores  indicates  a  general  west -to- 
east  drift  in  which  the  northerly  movements  {wedom- 
inate;!  slightly  above  those  toward  the  south.    Time- 
areal  distribution  of  recoveries  from  this  transect  sug- 
gested no  gyral  motion  of  surface  water  in  southern 
Lake  Michigan  during  the  time  the  units  were  adrift. 

Recoveries  of  drift  envelopes  from  releases  along 
the  South  Haven-Waukegan  transect  were  low  (fig.  4). 
The  location  ofrecovery  points  of  bottles  and  envelopes 
released  at  the  4  westernmost  stations  were  significantly 
different;  the  envelopes  exhibited  a  much  greater  ten- 
dency to  drift  to  the  south  than  did  the  bottles. 

Grand  Haven -Milwaukee  transect.  —Returns  from 
drift  units  released  along  the  Grand  Haven -Milwaukee 
transect  July  9  and  July  29  had  many  similarities  (figs. 
5  and  6).    Recoveries  from  the  August  19  and  Septem- 
ber 9-11  (strong  winds  prevented  completion  of  the 
transect  on  September  9)  transects  resembled  each  other, 
but  differences  between  these  two  pairs  of  observations 
were  substantial.    Discrepancies  between  results  from 
bottles  and  envelopes  were  less  pronounced  than  those 
of  the  South  Haven-Waukegan  transect. 

Recoveries  from  the  releases  made  on  July  9  sug- 
gest that  a  littoral  current  was  flowing  inshore  to  the 
north  off  Grand  Haven,  whereas  surface -current  move- 
ments were  toward  the  south  farther  offehore  (fig.  S). 
Recoveries  from  releases  along  the  western  half  of  the 
transect  were  obtained  from  several  directions  but  those 
from  the  2  most  westerly  stations  indicate  a  northward 


drift  similar  to  that  on  the  east  shore.    The  more 
definitely  eastward  drift  between  midlake  and  the 
2  most  westerly  stations  constituted  a  small  differ- 
ence between  the  July  9  and  July  29  transects.  The 
littoral  current  to  the  north  appeared  again  inshore 
off  Grand  Haven  following  the  July  29  releases,  and 
flow  was  to  the  south  from  the  next  6  stations.    The 
recoveries  from  the  releases  along  the  western  half 
of  the  transect  were  widely  scattered,  and  the  north- 
bound current  was  still  present  near  the  west  shore. 
Winds  in  July  and  August  had  slightly  greater  compo- 
nents from  the  north  than  from  any  other  direction  al- 
though variability  was  high  in  August  (fig.  3).    It  is 
apparent  from  the  recoveries  of  the  July  9  and  July 
29  releases  that  no  clearly  defined  counterclockwise 
whirl  as  posmlated  by  Harrington  (1895)  had  develop- 
ed in  the  southern  portion  of  the  lake.    Rather,  sur- 
face water  movenients  tended  to  be  clockwise  as  de- 
scribed by  Ayers  et  al.  (1958). 

At  the  time  the  battles  of  the  August  19  and 
September  9-11  releases  were  adrift  the  littoral  cur- 
rent flowing  to  the  ncxth  off  Grand  Haven  had  broad- 
ened to  include  the  eastern  10  miles  of  the  lake  (Aug- 
ust releases)  and  later  the  eastern  half  (September 
transect).  Recoveries  from  the  midlake  area  between 
inshore  stations  were  made  mostly  from  Michigan. 
The  north-bound  current  that  existed  along  the  Wis- 
consin shore  had  disappeared;  recoveries  from  the  2 
inshore  stations  were  scattered. 

The  few  drift  envelopes  recovered  from  re- 
leases on  the  same  dates  at  inshore  stations  on  this 
transect  had  followed  courses  generally  similar  to 
those  followed  by  bottles  (fig,  6). 

Ludington -Manitowoc  transect.  --Recoveries 
from  bottles  liberated  on  the  Ludington -Manitowoc 
transect  cm?  August  23-25  indicate  movement  of  sur- 
face water  both  to  the  north  and  south  off  Ludington 
(fig.  7).    A  similar  condition  existed  off  Manitowoc 
where  there  was  evidence  of  a  north-bound  current 
inshore  and  a  south-bound  one  farther  offshore.    Di- 
rection of  recovery  from  the  remaining  stations  was 
extremely  variable. 

Time  distribution  of  recovery  at  the  first  sta- 
tion off  Ludington  suggests  the  possibility  that  aU 
bottles  at  first  were  carried  to  the  north  of  the  re- 
lease station  where  four  landed;   subsequently,  a 
change  of  the  current  from  north  to  south  would  ac- 
count for  the  recovery  of  bottles  to  the  south  of  the

release  station.  The  possibility  exists  also  that  the 
bottles  at  this  station  were  leleased  in  an  aiea  of 
mixing  between  north-  and  south -bound  cunents. 

None  of  the  110  drift  cards  released  on  the 
Ludington -Manitowoc  transect  were  recovered. 

I  have  talked  to  commercial  fishermen  from 
Liidington  who  speak  freely  of  currents  "in  and  out.  " 
They  report  that  frequently  currents  flow  in  com- 
pletely opposite  directions  along  a  north-south  line 
a  short  distance  offshore,  and  report  also  an  incon- 
stancy of  these  currents,  which  often  change  from 
one  day  to  the  next. 

Rate  of  drift.  --The  average  rate  of  drift  for  all 
bottles  released  on  the  7  crossings  ranged  from  1. 0 
to  2. 1  miles  per  day  compared  to  1. 3  to  5. 7  miles 
per  day  for  drift  envelopes  (table  4).  The  difference 
in  mean  rate  of  drift  between  envelopes  and  bottles 
is  not  as  great  as  appears  from  these  averages.    Re- 
coveries of  drift  envelopes  were  nearly  all  from  re  - 
leases  at  inshore  stations  whereas  drift  bottles  were 
recovered  from  all  stations.  In  general,  rates  of  drift 
for  bottles  released  at  inshore  stations  were  higher 
than  the  rates  for  bottles  released  offshore.    Bias  be- 
cause of  difference  in  recovery  pattem  can  be  elim- 
inated partially  by  comparing  rates  only  for  recovery 
of  units  from  stations  where  both  envelopes  and  bot- 
tles were  recovered.  From  26  of  such  stations,  20  in- 
dicated faster  drift  rates  for  envelopes  than  for  bot- 
tles (table  4);  thus  a  real  difference  exists  between 
the  two  units. 

The  slow  drift  of  bottles  released  at  offshore 
stations  (table  4)  suggests  the  possibility  of  gyral 
movement  of  surface  water.    Calculated  drift  rates 
of  bottles  moving  in  curved  paths  to  landing  points 
would  be  lower  than  actual  rates  of  movement  since 
a  straight  line  was  used  from  release  to  recovery 
point  in  determining  distance  traveled. 

Rates  for  some  individual  bottles  were  very 
much  higher  than  the  average,  especially  for  those 
released  in  the  littoral  zone.  Three  bottles  released 
at  the  station  nearest  Grand  Haven  on  August  19 
traveled  slightly  more  than  100  miles  to  the  north  at 
a  rate  of  approximately  10  miles  per  day  (table  9). 
A  similar  rapid  drift  to  the  north  had  occurred  3 
weeks  previously  when  3  bottles  traveled  16  miles 
to  the  north  in  2  days  (table  9). 


General  characteristics  of  surface-water  move- 
ments. "The  surface -cunent  pattem  in  southern  Lake 
Michigan  in  1954  was  not  stable.    Over  any  one  tran- 
sect the  current  had  changed  from  one  release  date  to 
the  next.    The  littoral  current  to  the  north  off  Grand 
Haven  appears  to  have  been  the  most  stable;  it  was  ap- 
parent from  recoveries  made  from  releases  at  four  dif- 
ferent times.  A  similar  north -bound  littoral  current  off 
South  Haven  followed  both  the  August  3  and  September 
15  releases  (fig.  4).    From  the  remaining  areas  drift 
was  mainly  from  west  to  east  except  that  recoveries  from 
the  southwestern  quarter  of  the  lake  were  made  in  equal 
numbers  along  the  east  and  west  shores. 

Central  and  Northern  Lake  Michigan,  1955 

Grand  Haven  -Manitowoc  -Sturgeon  Bay  transects.  — 
The  Grand  Haven -Manitowoc  section  was  traveled  on 
April  26  and  the  Manitowoc-Sturgeon  Bay  leg  on  April 
27.    The  recoveries  from  drift  bottles  released  on  the 
two  days  were  mostly  from  Michigan  shores  (282  of 
325  units).    Most  bottles  were  recovered  north  of  their 
release  station  (figs.  9-10).   Movements  of  bottles  with 
drags  and  sand -ballasted  bottles  released  on  April  26 
were  similar  whereas  the  drift  of  the  two  types  of 
bottles  differed  significantly  on  the  Manitowoc-Stur- 
geon Bay  leg  (figs.  9-10).    Most  of  the  sand -ballasted 
bottles  were  recovered  from  the  eastern  shores  of  the 
lake  (34  of  44  bottles  recovered),  whereas  well  over 
half  of  the  bottles  with  drags  (29  of  41)  were  recovered 
from  the  northern  and  western  shores. 

The  north -bound  littoral  current  off  Grand  Haven, 
found  consistently  in  the  1954  studies,    was  evident 
again  as  is  shown  by  the  recoveries  from  the  liberations  on 
April  26. 

The  prevailing  winds  for  May,  when  most  of  the 
bottles  released  April  26-27  were  adrift,  were  from  the 
southwest  and  northwest  (fig.  8,  table  5). 

Ludington -Manitowoc  transect.  --Movements  of 
drift  bottles  with  drags  and  sand -ballasted  bottles  re- 
leased on  the  Ludington -Manitowoc  transect  were  in 
good  agreement.    The  first  of  the  5  transects  was  made 
on  May  13  when  240  units  were  released.    Bottles  re- 
leased on  this  date  appeared  in  general  to  move  in  a 
counterclockwise  pattern  (figs.   11-12).    Most  of  those 
from  the  3  westernmost  stations  moved  southward  but, 
from  these  stations  eastward  the  trend  was  increasing  to 
the  east  and  north.

NUMBER  OF  DRIFT 
BOTTLES  RECOVERED 


Figure  12,  --Release  stations,  numbers  recovered,  and  directions  of  recovery  points  of 
sand -ballasted  bottles  released  in  1955  on  the  Ludington -Manitowoc 


transect. 


23 


The  most  prominent  featuie  in  the  recoveries  of 
the  units  liberated  on  June  26  was  the  movement  al- 
most exclusively  to  the  north  and  east  of  release  sta- 
tions.   Ayers  et  al.  (1958)  noted  a  similar  movement 
of  drift  bottles  released  June  28  and  29,  1955,  in  this 
area.    Only  near  the  Michigan  shore  did  any  substan- 
tial numbers  drift  to  the  south.  In  July,  when  the  major 
number  of  these  bottles  were  adrift,  the  percentage  of 
southwest  winds  was  high  (fig.  8). 

A  major  change  in  circulation  from  that  shown 
by  the  recoveries  from  the  May  13  releases  had  oc- 
cuned  in  the  western  area  of  the  lake  by  June  26  or 
shortly  thereafter.    After  May  13  the  drift  was  to  the 
south  whereas  subsequent  to  the  June  26  releases  the 
drift  was  to  the  north  (figs.  11-12). 

The  drift  of  units  released  on  August  11  was  par- 
ticularly complicated  (figs.  11-12).    The  movement 
in  general  was  from  west  to  east,    apparently  under 
the  influence  of  the  pcevailing  westerly  winds  of  Aug- 
ust and  September  (fig.  8),    but  recoveries  from  re- 
leases at  adjacent  stations  frequently  were  many  miles 
apart  on  the  east  shores.    An  unusual  combinaticm  of 
wind  stress  and  density  distribution  probably  caused 
the  widespread  recovery.    Evidence  of  exceptional 
conditions  comes  from  the  major  fluctuati(xis  in  water 
temperatures  first  detected  by  the  M/V  Cisco  off  Lud- 
ington  on  August  9,   2  days  before  the  drift  bottles 
were  released.    Sharp  decreases  in  the  water  temper- 
ature of  the  upper  layers  continued  until  the  surface- 
water  temperature  had  dropped  to  4.  8°C.  on  August  14, 
2  miles  offshcxe  north  of  Ludington.    The  "normal" 
surface-water  temperature  in  the  area  at  this  time  of 
year  is  near  20.  0°  C.    Ayers  &.  aL  (1958)  also  found 
the  cold  water  along  the  east  shore  as  well  as  a  major 
north -south  current  in  the  area  on  synoptic  surveys  of 
August  9  and  10.  They  attributed  this  condition  to  the 
following  situation:  "When  effective  wind  stress  in  the 
Straits  is  from  directions  too  far  north  or  east  of  normal, 
wind  -driven  surface  water  transport  (current)  is  directed 
back  into  Lake  Michigan  where  it  induces  modifica- 
tion of  the  normal  current  pattern.  " 

The  pronounced  south -bound  east -shore  current 
described  by  Ayers  is  not  substantiated  by  returns  of 
drift  bottles  with  drags  released  August  11  at  the  second 
and  fourth  stations  west  of  Ludington  (fig.  11).    Bot- 
tles released  at  these  stations  were  recovered  mainly 
to  the  northeast  and  had  traveled  at  relatively  rapid 
rates.    Ayers  et  al.  (1958)  believed,   however,    that 


shortly  after  August  10  (the  date  of  his  last  synoptic 
survey)  the  north-bound  current  was  soon  re-estab- 
lished. This  belief,  if  true,  could  account  for  the 
recovery  locations  of  bottles  released  at  stations  2 
and  4,  but  would  not,  however,  account  for  recov- 
ery to  the  south  of  bottles  released  at  station  3. 

The  recoveries  from  the  bottles  released  in  Sept- 
tember  26  and  November  8  exhibited  a  general  west- 
to-east  drift  caused  presumably  by  the  westerly  winds 
that  predominated  in  October  and  November  (fig.  8). 

Frankfort -Sturgeon  Bay  transect.  — The  transects 
from  Frankfort  to  Sturgeon  Bay  offer  still  another  ex- 
ample of  the  considerable  variability  of  surface  cur- 
rents and  also  give  another  example  of  the  similarity 
of  results  from  releases  of  bottles  with  drags  and  bot- 
tles ballasted  with  sand. 

The  recoveries  of  the  releases  made  on  the  tran- 
sect on  May  16  and  17  (strong  winds  prevented  com- 
pletion of  the  transect  on  May  16)  disclose  a  pattern 
remarkably  similar  to  the  recoveries  from  the  Luding- 
ton-Manitowoc  releases  3  days  earlier.    The  littoral 
current  on  the  east  shore  was  north -bound  and  that  on 
the  west  shore  was  south-bound.    Recoveries  from  the 
intermediate  stations  were  made  mostly  to  the  east 
and  north,  particularly  for  stations  to  the  east  of  the 
middle  of  the  lake  (figs.  13-14).  Recoveries  from  the 
releases  of  June  23  disclose  that  the  surface  drift  had 
shifted  from  south  to  north  in  the  western  area  of  the 
lake.    The  distribution  of  recoveries  for  this  transect 
was  similar  to  that  of  the  recoveries  from  the  Luding- 
ton-Manitowoc  transect  3  days  later  in  that  the  drift 
was  almost  entfrely  northward. 

The  bottles  released  on  August  19  moved  in  a 
more  consistent  pattern  than  did  those  of  the  releases 
8  days  earlier  on  the  Ludington-Manitowoc  transect 
(figs.  13-14).    Thermograph  records  from  the  M/V 
Cisco  on  August  15  off  Ludington  show  an  increase  of 
surface-water  temperatures  over  those  during  the  major 
upwelling  a  week  earlier.    By  August  19  surface  tem- 
peratures off  Frankfort  (19°  to  24°  C. )  were  again  near 
normal  for  mid -August  and  drift -bottle  movement  to 
the  north  from  releases  near  shore  off  Frankfort  suggest 
that  the  "normal"  north -bound  cunent  had  become  re- 
established along  the  east  shore. 

The  drift  from  the  September  22  and  November  4 
liberations  was  generally  from  west  to  east  except  in

the  western  part  of  the  lake  (figs.   13-14).    The  mass 
landing  on  the  Wisconsin  shore  from  the  2  westernmost 
stations  from  the  September  22  releases  may  have  been 
caused  by  east  winds.    The  U.  S.  Coast  Guard  station 
at  Sturgeon  Bay  reported  east  winds  from  2  days  before 
until  1  day  after  release. 

If  Ayers  et  al.  (1958)  were  correct  in  their  con- 
clusion that  winds  too  far  north  or  east  of  normal  in 
the  Straits  of  Mackinac  cause  modification  of  the  nor- 
mal flow  (normal  being  north-bound  off  the  east  shore), 
north  or  east  winds  must  have  been  strong  on  or  about 
September  22  to  cause  the  prominent  southward  flow 
off  Frankfort  (figs.  13-14).  Wind  observations  at  U.S. 
Coast  Guard  stations  on  Beaver  Island  and  at  Manistee, 
Michigan  (table  6),  support  their  conclusion. 

Charlevoix  -Manistique  transect.  —The  returns 
from  releases  of  bottles  along  this,  the  most  northerly 
of  transects,  exhibited  many  similarities  to  those  from 
releases  at  corresponding  dates  along  more  southerly 
transects.  The  data  for  bottles  with  drags  and  for  sand- 
ballasted  bottles  agreed  well  again  except  for  inshore 
stations  off  Charlevoix. 

The  recoveries  of  bottles  released  on  June  5  re- 
sembled those  from  the  first  Ludington -Manitowoc  and 
Frankfort -Sturgeon  Bay  releases  in  that  the  drift  was 
essentially  counterclockwise  (figs.  15-16).    The  direc- 
tion of  drift  of  sand -ballasted  bottles  and  bottles  with 
drags  differed  at  the  first  two  stations  off  Charlevoix  on 
June  5  (figs.  15-16).    The  bottles  with  drags  drifted  to 
the  northeast  whereas  the  sand -ballasted  bottles  were 
recovered  mostly  from  the  southwest. 

On  July  14,  nearly  6  weeks  after  the  first  releases 
on  this  transect,  the  littoral  cmrent  on  the  west  shcxe 
was  to  the  northeast  instead  of  southwest.    The  returns 
from  the  remaining  stations  were  similar  to  those  of 
the  June  5  transect  (figs.   15-16). 

The  recoveries  from  releases  made  on  the  Sep- 
tember 5  transect  exhibit  few  clear  trends  (figs.  17-18). 
No  strong  Unoral  cunents  were  evident,  and  many  bot- 
tles released  in  the  center  of  the  lake  traveled  to  the 
west  shore  and  north  to  the  islands. 

West -to-east  drift  had  reappeared  by  late  Octo- 
ber and  November,  as  evidenced  by  recoveries  of  the 
October  19  releases  (figs.  17-18). 

Rate  of  drift.  --The  average  drift  rate  of  the  bot- 


tles with  drags  was  1.  5  mUes  per  day  as  compared 
to  1. 8  miles  per  day  for  the  sand -ballasted  bottles 
(table  2).  On  3  of  16transects,  however,  the  drift 
rate  of  the  bottles  with  drags  was  higher  than  that 
of  the  sand-ballasted  bottles.     A  very  high  rate 
of  drift  for  a  bottle  with  drag  was  for  one  that  travel- 
ed 64  miles  across  the  lake  from  west  to  east  in  10 
days,  a  drift  rate  of  6.4  miles  per  day  (table  17). 
A  sand -ballasted  bottle  released  at  an  adjacent  sta- 
tion made  a  65 -mile  crossing  in  9  days,  a  drift  rate 
of  7. 2  miles  per  day  (table  18).    These  bottles  were 
released  on  November  8  at  stations  7  and  8  respec- 
tively on  the  Ludington -Manitowoc  transect.    The 
Sturgeon  Bay  Coast  Guard  station  reported  prevail- 
ing westerly  winds  for  the  10  days  following  release 
of  these  bottles  on  November  8,  and  southwest  winds 
of  Beaufort  10  (55  to  63  mUes  per  hour)  on  November 
16.  The  maximum  drift  rate  for  sand -ballasted  bot- 
tles (11.0  miles  per  day)  occurred  for  2  bottles  re- 
leased on  November  4,  approximately  15  mUes  east 
of  Sturgeon  Bay,  Wisconsin  (table  20),  Both  types  of 
units  released  at  station  4(approximately  15  mUes 
west  of  Ludington,  Michigan)  on  June  26  traveled  to 
the  north  at  high  rates  of  drift;  a  sand -ballasted  bot- 
tle traveled  115  miles  in  14  days  (8. 2  miles  per  day, 
table  18)  and  a  bottle  with  drag  87  miles  in  14  days 
(6. 2  mUes  per  day,  table  17).    During  these  14  days 
the  Manistee  Coast  Guard  station  reported  57  obser- 
vations of  winds  with  a  southerly  component  (wind 
from  the  south),  11  northerly,  26  westerly,  and  16 
easterly;  the  south  winds  were  slightly  stronger  than 
those  from  any  other  direction.  The  overwhelmingly 
predominance  of  south  winds  over  north  winds  and 
the  relatively  greater  number  of  west  winds  over  east 
winds  doubtless  account  for  this  rapid  drift  rate  to  the 
northeast. 

General  characteristics.  --The  north -bound  lit- 
toral cunent  found  off  Grand  Haven  in  1954  was  evi- 
dent in  1955  as  is  shown  by  the  recoveries  from  bot- 
Ues  released  April  26  (figs,  9-10), 

In  central  areas  of  the  lake,  drift  was  generally 
west  to  east  and  south  to  north.    Greatest  deviation 
from  this  pattern  followed  the  release  of  bottles  Aug- 
ust 11  on  the  Ludington-Manitowoc  crossing  (figs,  11- 
12)  when  drift  to  the  south  was  equally  as  prominent 
as  drift  to  the  north. 

In  the  northern  areas  of  the  lake,  drift  was 
mainly  west  to  east.

SUMMARY 

1.  The  U.  S.  Bureau  of  Commercial  Fisheries 
conducted  surface -cunent  studies  with  drift  bottles, 
drift  envelopes,  and  cylindrical  plastic  tubes  as  part 
of  fishery  and  Umnological  investigations  of  Lake 
Michigan  in  1954  and  1955. 

2.  Releases  in  central  and  southern  Lake  Mich- 
igan in  1954  were:    1,  080  drift  bottles,   1,  080  drift 
envelopes,    and  100  plastic  tubes.    Dates  of  release 
were  between  July  9  and  September  15.  Returns  were 
received  of  587  reply  cards  from  drift  bottles,  77  from 
drift  envelopes,  and  18  from  plastic  tubes.    The  dis- 
ttibution  of  these  returns  indicated  that  no  stable  pat- 
tern of  surface  currents  existed  in  the  summer  of  1954. 
In  general,  the  drift  was  west  to  east;  movements  to 
the  north  or  south  were  about  equal. 

3.  Releases  in  1955  in  central  and  northern  Lake 
Michigan  between  April  26  and  November  8  totaled 
2,  000  sand-baUasted  drift  bottles  and  2,  000  drift  bot- 
tles with  drags.    Returns  were  received  of  1.  060  reply 
cards  from  sand -ballasted  bottles  and  1, 128  from  bot- 
tles with  drags.    In  1955  as  in  1954  surface  currents  in 
Lake  Michigan  exhibited  no  stable  pattern.    Drift  in 
general  was  west  to  east;  drift  in  the  eastern  areas  was 
mainly  to  the  north  but  that  in  the  western  area  show- 
ed no  prevailing  pattern.

APPENDIX 

Tables  7-22  in  the  appendix  contain  release  and 
recovery  points  of  drift  units,  dates  of  release  and  re- 
covery, number  of  days  units  were  adrift,  miles  cov- 
ered, and  average  drift  rates  in  miles  per  day.    Sta-   " 
tions  are  located  on  figures  4-7;  9-18  by  counting  from 
right  to  left  (east  to  westy  with  the  exception  of  the 
Manitowoc -Sturgeon  Bay  transect  (figs.  9-10);  on  this 
transect  stations  are  located  by  counting  from  south  to 
north. 

For  units  released  in  1954,  recoveries  are  listed 
up  to  January  31,  1955;  for  those  released  in  1955,  re- 
coveries are  listed  up  to  January  31,  1956. 

Ten  bottles  and  10  envelopes  were  released  in 
1954  at  each  station  (tables  7-12)  with  the  exception 
of  the  releases  July  9  on  the  Grand  Haven -Milwaukee 
transect;  on  this  date  6eachofthe3types  of  units  were 
released  at  all  stations  except  the  first  out  of  Milwau- 
kee at  which  4  of  each  type  were  released.    Data  on 
the  plastic  tubes  have  not  been  included  in  the  tables. 

Ten  bottles  with  drags  and  10  sand -ballasted 
bottles  were  released  in  1955  at  each  station  (tables 
13-22).
