Yesterday we went upstream of Woodcock dam to collect and compare the diversity of species. We found that water pennies, mayflies, blackfly larvae were abundant. All the species we found were between the moderate to sensitive range. This means that upstream is healthier. Crayfish all seemed to want to be caught. In the end, we found about ten crayfish ranging from small to large in size.
