Moderate autumn rains


November can be a time of prolonged and quite intense rainfall, but this year there are only three moderate events in the first half of the month. The event of 8-9th November included about 40mm total precipitation with hourly intensities up to about 7mm/h.

Autumn dry season

Stage = 0.370m, Q = 0.538m3/s

October can be very fine and dry. This year we experienced very little rain during the two weeks 10-24 October, and stage dropped to levels similar to summer minimum flows.

Again overall the match is good between the two stage recording systems, although the Hobo logger memory became full as I had not been resetting the logger since August. Resetting the logger to a 10 minute interval means that it will be able to log for 5 months until next April. This will avoid the need to remove the logger from the water column during the winter in snowy conditions. The Kadec system definitely has the advantage of more easily downloading the data, although even then it is not really possible during heavy rain or snow.
