RBAST Stream Temperature Methods

The experiment compares a forested stream reach (full canopy cover) with a nearby stream reach with no tree or shrub canopy cover (open) of Valley Creek in east-central Minnesota. The section of the stream we are studying is located at the Belwin Conservancy. Stream water temperature was measured every 15 minutes at the upper and lower ends of each reach using dataloggers. The differences in temperature between the upstream and downstream ends of the reach were calculated for each time period. Water depth was logged at the middle of each reach. Air temperature and PAR were also logged at the middle of each reach.
