covered by small, flat, granite rocks with individual surface areas of not 

 more than 0.5 m 2 . Smaller flat, granite rocks (x=8 cm diameter) covered 

 approximately 15% of the bottom. Ten percent of the study area was 

 commonly covered with leaf beds during fall through early spring 

 months. The stream banks had a 2:1 slope, and were commonly under- 

 cut and pocked with numerous animal burrows. 



Mean width of the stream at the standard control site for this area 

 was 13 m, with an average depth of 1.5 m. The greatest increase in 

 depth recorded was 2.4 m, although greater depths may have been 

 obtained during severe flooding when monitoring was not possible. The 

 shallowest depth recorded at the control site was 48 cm, with seasonal 

 fluctuations averaging +34 cm. Water temperatures at the standard site 

 ranged from 1°C to 21°C with seasonal fluctuations in temperature sim- 

 ilar to those at Site No. 1. Dissolved oxygen levels ranged from 5.4 ppm 

 to 8.0 ppm (x=7.2 ppm). Turbidity levels of 16 to 40 ftu (x=31.5 ftu) 

 were recorded. Table 1 summarizes the physicochemical data for both 

 sites.
