General studies : November, 1967 / by John C. Ayers, Joseph C. K. Huang.

2

eight numbered items below. The present status of each item is
shown.
1. Bathymetric survey off site,.including consideration
of bottom stability.
Complete and reported, including early-spring check
on effect of winter ice on the nature and position
of the sand bars.
2. Bottom-type survey off site.
Complete and reported.
3. Determination of alongshore current direction under
various wind directions.
Delayed by inability to obtain required instruments
and by winter ice. Now under way.
4. Determination, by dye dilution experiments, of the
inherent diluting capacity of alongshore currents at
the site.
Some runs have been made, more can be made if required.
5. Determinations of the locations of local potable water
intakes and of the possibility of plant effluent reaching
them.
Complete and reported.
6. Ecological study of thermal pollution and its effects.
Will be handled by Dr. C. F. Powers. As a basic preliminary to this study the numbers and distributions
of bottom-living organisms off the plant site have
been determined and reported.
7. Estimates of dilution and dispersion of thermal effluent
from the plant.
Completed and reported, but will be amended if work
now under way permits better estimates.
8. Studies of unusual conditions. Extraordinary seiches are
the only item in this section.
Completed and reported.
B. PHYSICAL LIMNOLOGY
1. REGIONAL FEATURES
The Berrien County power plant site is located on the southeastern shore of Lake Michigan in a region where land topography
and lake-bottom topography both show the effects of glaciation.
