Channels

The river in these three images is very different each time. As you can see in the 1927 image the area where salmon hole is, is covered in water. There are also less islands in the middle of the river. Since the water was a lot higher that is why the river is much wider in that image than it is in the next two. We can only assume that that water in the 1927 image is packed with sediment due to the nature of the flood. In the 2004 image you can see the water is very dark blue, it does not appear that there is a lot of sediment stirred up. The islands are larger in the middle of the river. In the 2020 image the water is brown with sediments. It appears that the middle islands have changed into one large island between 2004 and 2020.

Above is my whole table of data for the maximum annual streamflow.

The variability for the maximum streamflow table had more variation. The fact that the 1927 flood was so much higher than the rest heavily impacted the data set. The average maximum flow is much larger than the annual average flow. What I noticed from the datasets is that there is not a lot of variability in the average annual streamflow. As you can see the % standard deviation for that dataset is only 24.3%. The percent standard deviation for the maximum streamflow is 52.1%. This shows that the data points for the average annual streamflow as a whole are much closer together than the data points for the maximum streamflow.
