Rainy season?


So far not so much precipitation in July. End of June saw some moderate rainfall and peak stage of about 1.0m. The hydrograph below shows the data from the Kadec logger which was reset in a new sensor pipe on June 5. During lower flows there is some instability in the stage readings which is not showing in the Hobo stage data. Suspected problems in the Kadec sensor (temperature/atmospheric compensation not functioning?) mean we should consider installing a second Hobo logger as back-up and retire the 19 year old Kadec soon.
