On May 9, 2011 Travis, Riley, and Olivia went to Site 3 at Douglas Creek our site is 100ft long. First I’ll tell about our site’s channel. The shape in the cross-section was a U. The longitudinal pattern was meandering. Next I’ll tell you about the reach habitat. The number of riffles was1the percentage of riffles was 10%. The number of pools was 1 the percentage of pools were 15%. The woody debris was moderate. The organic debris was sparse. Now I’ll tell you about the riparian zone when you’re looking down stream 100ft down. On the right its 50-100ft wide and on the left bank it was the same. That’s all in the riparian zone. Next I’ll tell you about the vegetation the conifer has 0% the deciduous has 30% the shrubs have 50% the grass and herbs have 75%. Now I’ll tell you about the over head canopy. It’s 0-25%. Next I’ll tell you about the stream bank the vegetation cover was abundant. Next I’ll tell you about the artificial structures. In stream reach there are some litter/garbage and a port a potty. In conclusion our site is very interesting.
