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

at 1 mile perpendicular to shore, a station which should be both a part of
the lake-wide surveys and a part of the plant's local detailed surveys in
order that the local surveys would be tied to the lake-wide conditions.
We were forced, by conditions of no capturable benthos or unsampleable
bottom or both, to relocate the following plant-site stations farther off
shore: BAILLY, to 2 miles off shore, sediment sampleable but little or no
benthos; KEW, to 3-1/2 miles off shore, sediment hard and unsampleable and
little or no benthos; PTB, to 4 miles off shore, sediment hard and unsampleable and little or no benthos. At the relocated stations both sediment and
benthos can be obtained in the required quantities.
Our present and past evidence indicates that at KEW and PTB the inshore
condition consists of migrating gravel bars travelling over a basic bottom of
hard red clay. We consider the relocation off shore to be necessary if reliable benthos and sediment samples are to be gotten.
It is here noted for the record that sediment station F-6 is apparently
traversed by waves of clean coarse sand (sampled on 1 September) which, when
absent, leave cobbles that cannot be adequately sampled (2 November). When
sediment samples could be obtained at this station they were taken.
The stations of the survey are tabulated below by station designation,
distance off shore (in the cases of the nuclear plant sites), the latitude N
and longitude W, and the station type.
Each of the station locations are indicated on the included orientation
chart of Lake Michigan.
