Today I went to the Envirathon and placed 4th as a team. It was very interesting and educational. I am rewording what Eric wrote on his blog since I did not get back in time and did not know went on.
Today its very hot out. The stream has not gotten any lower and the water flow is the same. A few of our class mates got lost walking down to the creek so we lost some time because we almost had to go back up. dan and i started by searching under some of the larger rocks in our area, we found some smaller bugs but before we could get a cameria they either got away or jumped back into the water.( hard to hold onto) I can describe that they were about one half inch long. with legs on both sides. 2 tenicles and small eyes. It was black. We saw some more of the chubs that are living in our area aswell. We feel that our area is the best environment for these fish because it is one of the deeper spots in the stream. We have large rocks that can hid the fish from predators, and deeper water which will keep them in the hot summer months. The deeper the water, the colder it is. We took rocks and Slowed down the water and in return it got much deeper, 14 inches deep in on spot. We noticed that the larger chub stayed around that area, and we think that there is more water flow so the larger fish would perfer that area. There seems to be lots of food for fish in this stream, Crayfish, bugs, helgermites, mayflies are perfect food for fish. Chubs will eat these creatures and stay healthy. We expect to get lots of rain tonight, if that happens its going to change our area and the fish may get sweeped out. The water flow may get to powerful for the small fish and push them down steam. Rocks may have the tendancy to move due to high water pressure and logs or sticks may get pushed down and move things from what they were the day before. It is possible to have new organisms if they get moved from the groups up stream. A few additional crayfish would be nice to observe in our area. After we did all this, we went back inside.
