Station 6 was a spring-fed pool adjacent to the bluff. Sampling 
was done by fish traps except in May and June, when 10-square 
meter seine hauls were made. The oxygen readings for November- 
March ranged from 7.5 ppm to 12.2 ppm and averaged 9.5 ppm, and 
for April-October ranged from 4.2 ppm to 9.4 ppm and averaged 7.2 
ppm. The water temperature was also more constant than at the 
other stations, with the winter readings averaging 11.9°C and 
the summer readings 14.9°C. The vegetation wad dominated by a 
two-to three-inch layer of duckweed and an abundance of Naster- 
tium officinale. Four species were collected.

Station 7 was a large, open-water area with little vegetation. 
The average area sampled was 121 square meters, the depth 1.5 
meters. For July through September (the only months the station 
was sampled because of its depth), the oxygen averaged 5.9 ppm 
and the water temperature averaged 19.5°C. The shoreline vege- 
tation was predominantly NelLumbo lutea. Fourteen fish species 
were collected.
