Lake Michigan environmental survey : final report / [edited] by John C. Ayers.

PREFACE

STATION LOCATIONS
The 50 lake-sampling stations of the Lake Michigan Environmental Survey
followed the lay-out of lake-monitoring stations that the University of Michigan's Great Lakes Research Division has followed fairly consistently since
1962. Of these the A-line (Benton Harbor, Mich., to the Chicago region), the
C-line (Holland, Mich., to Racine, Wis.) and the E-line (Frankfort, Mich., to
Kewaunee, Wis.) have been occupied most consistently, for experience showed
that the B-line and the D-line were not necessary to adequate biological and
chemical representation of the lower (southern) two-thirds of the lake.
For the Lake Michigan Environmental Survey all five (A through E) of the
original lines of stations were reactivated, with some local changes of station
positions, and the following additions were made: F-line from Big Rock near
Charlevoix to Manistique, Mich.; EF-line (between the E- and F-lines) from
Manitou Passage, Mich., to Porte des Mortes Passage, Wis.; CD-line (between
the C- and D-lines) from White Lake, Mich., to Port Washington, Wis.; and the
single station AB-1 (between the A- and B-lines) off Glencoe, Ill. The added
lines and station were adjudged necessary to provide a suitable coverage of all
those waters that are properly Lake Michigan: north of the F-line seiche
(wind tide) action can introduce Lake Huron water into what is geographically
Lake Michigan.
As mentioned at the beginning of the above paragraph, some stations of the
original 5 lines have been relocated within what is functionally the same
locality. Such relocated stations carry their original letter and number designation, but the number is primed, i.e.: A-6', B-7'. Each of the nuclear
plant sites is considered to be a part of a line of stations, and each bears
an unused equivalent station designation: COOK = A-l', BAILLY = A-7', PAL
(Palisades) = B-l', ZION = B-8', KEW (Kewaunee) = E-6', PTB (Point Beach) =
E-7', and BRK (Big Rock) = F-l'. There are, in these survey stations, no
stations A-2 or A-2' nor E-l or E-l'.
The station relocations reported above have been largely for order and
for convenience. It is, however, vital to report the following station relocations that were forced upon us by nature.
Our original plan and proposal envisioned, in front of each nuclear plant,
