September low flows

Very low flow conditions, equivalent to 1.17 mm/day (30 Sep)

Sand and woody debris deposited around the staff gauge

The month of September experienced exceptionally dry conditions this year, as shown by the stage hydrograph below. Only two minor precipitation events can be seen, and long periods of baseflow recession. The monthly runoff was one of the lowest on record for Takiya River, at just 46 mm. The lowest recorded monthly runoff during the period of record (2000-2019) was August 2012 with 35 mm.

Comparing the Kadec and Hobo stage data, it seems the newer Hobo logger is giving more stable data readings. Instability in the Kadec data during low flows could be due to effects of water temperature fluctuations not being compensated for adequately.
