Water chem and macros

On Tuesday morning we went to Woodcock creek upstream. We measured water quality by water chemistry and counting the macroinvertebrates. As a group we did several different water chemistry test, we tested the turbidity, dissolved oxygen, alkalinity an etc. To find different organisms we took kick net and put them in the water and we did the "creek shuffle" to get the macros to swim or go into the nets. Then we collected the macros and identified and counted how many we had.We then compared the data to the data from downstream and found that the macros are more diverse upstream than downstream but are less in numbers.
