Station 4, a fairly deep area of quiet water with a muck bottom, 
was situated along a beaver dam at the swamp's edge. The average 
area sampled was approximately 6 square meters and the depth was 
about 1 meter. The oxygen readings for November-March ranged 
from 1.4 ppm to 10.9 ppm and averaged 6.2 ppm, and for April- 
October ranged from 0.2 ppm to 8.0 ppm and averaged 2.8 ppm. The 
water temperature averaged 6.6 °C for the winter readings and 
21.8 °C for the summer readings. Partial shade was provided by 
Acer rzubsum and Nyssa caquatica. The station contained scattered 
duckweed and an abundance of CeratophyllLum demersum. Eight 
species were collected from the small area.

Station 5 was a densely vegetated area with a large spring located 
on its boundary. The average area sampled was approximately 11 
Square meters by 2/3 meters deep. The oxygen readings for 
November-March ranged from 3.8 ppm to 12.8 ppm, and averaged 8.1 
ppm, and for April-October ranged from 4.2 ppm to 9.4 ppm, and 
averaged 4.6 ppm. The water temperature averaged 8.8°C for the 
winter readings and 19.7°C for the summer readings. The station 
had a muck bottom covered by a layer of tupelo leaves. The entire 
area was shaded. Aquatic plants present in the station were Typha 
katifakia, Saururus cernuus, CeratophylLlLum demersum, and a very 
abundant species of Sptrogyra. Fourteen fish species were 
collected.
