Observation details

Overview

Estuary Barham River Estuary
Site Barham River Observation Site
Observation ID #12589
Date and Time Wednesday 12th December 2018 13:55pm
Approved Approved

Notes

Rainfall past 48 hrs = 0;  Atmospheric pressure = 1007.5 hPA.

Wide build-up of sand at mouth narrows mouth and river passage. 

Observed decrease in water level between 14:00 & 17:15 is more likely due to drawdown of river after the mouth opening in the prior 24 hrs, rather than to tidal influence. No upstream influence was observed at high tide. 

Vegetation growth over the years on the bank below the BmP3 observation point is starting to obscure vision of the estuary on the inland side. (e.g., compare image BmP3-3 with past images from the same data point taken in Dec 2012.)
