The document contains data from measurements taken at 5 sites along upper and lower streams. In the upper stream, pH ranged from 8.1-8.6, temperature from 17.4-18.8 C, and dissolved oxygen and flow speed were highest at sites with more animals. In the lower stream, pH was lower at 7.1-7.35, temperature ranged from 17.08-17.22 C, and dissolved oxygen and number of animals decreased with higher flow speeds. Overall, the upper stream had higher pH, dissolved oxygen, flow velocities and more species and animals than the lower stream.
