Early summer low flow

Stage = 30.5cm, Ta = 21.5C, Tw = 16.1C

The snowmelt season is over for the Takiya River Basin, and now we are waiting for the rainy season to arrive and swell the flow in the river. The hydrograph below shows that there is a false start to the rainy season around 20 June, after which dry conditions return. Together with late summer in September, this time of year before rainy season has some of the lowest flows of the year.

Tail end of snowmelt season


After 2-3 months of snowmelt and sustained moderately high flows, the past two weeks have seen a steady decline in stage. The snow-covered area has really decreased rapidly, and normally disappears by early June for Takiya River. Note the continued dry weather and diurnal snowmelt pattern, which contrasts with the single rainfall event of May 31st.

Today's special job was to use anti-rust paint on the logger boxes which hold the stage data loggers for Takiya River and the tributary. These steel boxes are highly rust resistent, but having been in the forest continuously for up to 13 years, some much needed maintenance was in order.

Stage = 38.5cm, Ta = 20.0C, Tw = 13.6C
