20-06-2018 Estuary Entrance Opening

Surf Coast Shire has artificially opened the estuary around 20th June. Water level (m AHD) at the bridge is still high at just on 2m AHD and Coastal Court and Butlers Bend monitoring sites are still underwater.

High tides 1.8m on Saturday and Sunday saw the sea go over the berm on both days. Photos are from Sunday 17th June at 2.40pm. Very windy day and a big sea following high rainfall. 1.9m AHD at the Bridge

The high 1.8m tide at 2.08pm broke over the berm and sea water entered the estuary. Not a lot of sea water but it looked like it may have happened a few times this week as there was quite a lot of seaweed over the berm. Estuary height was 1.4m

05-02-2018 Water level

On Monday February 5, Barwon Water increased releases from the Painkalac Reservoir into Painkalac Creek from 0.6-0.7 Mega Litres of water per day to  2 Mega Litres of water per day.  Releases will return to 0.6-0.7 Mega Litres of water per day on Thursday February 8.

This release of water is called a “Low Flow Fresh”.  A “Low Flow Fresh” is a small amount of water released over a short period of time (1-3 days).  This release of water mimics a localised rainfall event during a time when there is low freshwater flow (Dec-March).  The aim of the release is to maintain summer/autumn water quality, flush sediments from potential egg laying sites in the lead up to autumn fish breeding season and provide some depth variability on surfaces of large wood in the river channel.

If you would like to learn more about the water releases from the Painkalac Reservoir I suggest you  have a read of this report written in 2008
