Station 2 was a muck-bottomed area located on the swamp margin. 
The average area sampled was approximately 4 square meters, the 
average depth approximately 2/3 meter. The oxygen readings for 
November-March ranged from 1.6 ppm to 10.4 ppm and averaged 
5.0 ppm, and for April-October ranged from 0.3 ppm to 8.1 ppm 
and averaged 2.7 ppm. Water temperatures averaged 7.0°C for 
the winter readings and 22.5°C for the summer readings. The 
station contained an abundance of CerzatophylLlLum demersum and its 
Surface was covered by duckweed; the deep-side boundary opposite 
shore was densely populated by Nupharz advena and roots of 
Cephakanthus . Seven fish species were collected from the small 
area sampled.

Station 3 was swamp margin having very shallow water, and lo- 
cated near small spring emergences. The average area sampled 
was approximately 10 square meters, the average depth approxi- 
mately % meter. The oxygen readings for November-March ranged 
from 2.2 ppm to 9.9 ppm and averaged:7.0 ppm, and for April- 
October ranged from 0.3 ppm to 8.6 ppm and averaged 3.5 ppm. 
The water temperature averaged 7.1°C for the winter readings 
and 22.0°C for the summer readings. Station 3 was shaded by a 
thick tree cover of Nyssa aquatica. ‘The dead tupelo leaves 
formed a thick leaf-litter bottom, and dead and decaying logs 
and branches were scattered throughout the station. Other 
aquatic vegetation consisted of a thin scattered layer of 
duckweed and an abundance of CerzatophyllLum demersum. Twelve 
fish species were collected.
