They were also part of the team that was in charge of recording the time and weather conditions that were present. They were also responsible for setting a transect at the end of the ten meter length of the stream, running from one bank of the stream to another, they then set another transect five meters downstream and a third transect at the end of the ten meter stretch. On each of the transects that were set, a measuring tape was used to determine the bank to bank width of each transect. A meter stick was then used to measure the depth at each bank and in the middle of each transect. The physical parameters team also observed the creek bed in each of the transects to determine if they were sandy or gritty, and if they were contained a lot of rocks and boulders. This group also observed the flow rate of the stream using a flow meter that was provided. There were three recording that were taken in the middle of the stream and then the mean was
