Observation details

Overview

Estuary	Barham River Estuary
Site	Barham River Observation Site
Observation ID	#6501
Date and Time	Friday 30th December 2011 16:10pm
Approved	Approved

Notes

Rainfall last 48 hours : nil, Atmospheric Pressure 1020 hPa. Though the estuary mouth was closed, a very shallow berm blocked the mouth. At higher tides than 1.4m waves would break over the berm and raise the river level close to the mouth. Water staining on sandy river bank supports this supposition.
