Rising baseflows

Stage = 57cm, Ta = 7C, Tw = 10C

From the hydrograph below we can see that the stage has been quite high at 60-70cm during late November due to some steady rains. There are no large peaks, however, as rainfall intensities have been moderate. This has raised the baseflow level as we head into December.

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.
