Stream Quality Monitor Testing

The water was a little rough today. We had some rain but since it was over 24 hours since last rain, it was fine to continue with sampling. I did have to walk through some deeper water to get to the area of the river where I could perform accurate sample testing. Each of the three samples also came from different river locations.

I found that I would pull different macroinvertebrates from each of the three spots. For example, in one spots I pulled out about 30 Riffle Beetles and another spot I only pulled two. The second spot was a little deeper and the water was moving a little faster. It is interesting to learn how various factors play into the actual species and numbers found in different river locations that may be only be 15 feet apart.
