On the 15th of January our class went to Harry Hall Creek. Hank Lentfer came with us. He gave us two invertebrate nets! Invertebrate nets are nets that have very fine mesh in the bottom to catch very small insects on the bottom of the stream.
Hank told us a lot of things about Harry Hall Creek like, every winter since he has lived by the creek (15 years) he has not seen it frozen! Also, he and his daughter have seen salmon spawning in the creek.
A surprising thing was that the temperature of the water was 40˚F! Compared to the Glen’s Ditch temperature, (36˚F) that’s pretty warm! Another surprising thing was that the water was flowing 39 inches in three seconds!
When we got to Harry Hall Creek the weather was rainy, wet, dreary, and dark! We had no success with the nets. We caught nothing.
When we got back to the school, we had to wait five days before we could test the dissolved oxygen (according to the kit…), but, after five days we tested it and we got 5 ppm.
We all had a great time!
