Winter preparation

Snow lysimeter at the larch site

Today we did the last of the winter preparation by completing the cleaning and checking of the snow lysimeters at Takiya River. There are three snow lysimeters (larch site shown above, mature cedar site, and young cedar site) that monitor the runoff below the snowpack throughout the winter and spring seasons. At each site three large plastic trays collect the runoff and feed it through pipes to a large tipping bucket device (capacity 200mL and 500mL). In short, we are measuring the snowmelt and rain-on-snow runoff, and comparing between the three sites. This experiment has been running for 10 years now! So we can also look at the long-term trends and patterns.
