Diurnal melt pattern


During fine weather the daily fluctuations in air temperature strongly control snowmelt and the stream discharge as seen clearly in the hydrograph above. The level of flow in Takiya River remains high due to snowmelt. With continuing fine weather during the rest of May we expect to see these diurnal wave patterns becoming less pronounced and then disappearing altogether when the snowpack has fully melted off.

New forest road has been carved out of this narrow valley (starting 2012) to allow a partial cut of the cedars
