Douglass creek conclusion
The water at Douglass creek was good over all. The water at site 1 was good except the problem we messed up on our DO test the average was9-12 drops and ours was 52 drops. We don’t know why but we could assume that we had oxygen in our vial.
Our vegetation was good and was improving on the second trip and by the third trip it was great. Our water temperature was 40 degrees f every time. Our shape in cross-section was a U. our longitudinal pattern was straight.
We found many macro invertebrates. Most of those macro invertebrates were non tolerant. But some of the macro invertebrates were somewhat tolerant. This means that they live in places that can be dirty but only a little bit. Since we found tolerant macro invertebrates we can say that the water is good.
Other observations were that the water was very deep and muddy.
Over all the water at Douglass creek was good.

Site Survey
This is the survey for site 1 at Douglas creek 2011. The names of the observers are: TJ, Kylee and Jocelyn. Now we surveyed the artificial structure here. First there were huge culverts. A culvert is a vary large tunnel/hole that would drain water in case of a flood.
Next I will tell you about bank stability. Bank stability is like erosion and telling how much. At our site there was erosion in some areas. Now I will tell you about the stream reach. The vegetation cover on the bank was moderate. The artificial protection was 0%.
Further more I will now tell you about along side stream reach. So we found a road when we climbed up a hill. It had tire tracks on it so we know it was used. It was not a gravel road it was a dirt road. This is vegetation cover it was moderate. Moderate means medium. We also surveyed protection. Protection is about 0-25%. And that is protection. Another thing we surveyed was over head canapé is )-25% there were vary little trees growing over the water and that is the over head canapé. Now the channel, flat bottom and steep side. Finally I will tell you about the reach habitat. Here is the number of riffles the # of pools is three. The % of riffles is was 20% woody debris was none organic debris was sparse. And that’s reach habitat.

Macro Conclusion
Well as you can see we found 2 caddis fly, 2 stonefly and 4 Mayfly that is very good for the water because those are non tolerant larvas! My teacher Mrs. Petersen calls them the fancy people how go to the fancy hotels. We also found 2 Beetle larva and we found 4 dragonfly larva. This means the water is good overall. We also found some tolerant bugs but this is usual because they can live anywhere.
