Snow lysimeter fixed

Stage = 51.5cm, Ta = 4.6C, Tw = 9.2C


Today's work included measuring discharge for Takiya River and the tributary, then fixing the leak in the drainage pipe at the mature cedar snow lysimeter site. The third lysimeter tray had become disconnected at the elbow, likely when the tray was moved during a flood. We repositioned the tray and reconnected and glued the PVC pipe quite easily.

The first snows of winter have already fallen in Niigata. We could see snow on the mountains down to about 500m elevation. For the high peaks this snow will stay and accumulate right through the winter, but for the lower elevations the snow will come and go through autumn until winter arrives for real.
