Hydrographic Survey for Curalo
4 October 2017
The process of developing new Coastal Management Programs for the Shire’s estuaries continues, with Council working with the NSW Office of Environment and Heritage (OEH) to conduct a hydrographic survey of Eden’s Lake Curalo.
Planned to commence on Monday, 9 October, the survey work is expected to take a week to complete, as OEH and Council staff use all-terrain vehicles and a jet ski to access the estuary flat and main estuary channels of the lake.
The purpose of the survey is to map the lake bed and define underwater features such as sand shoals, with the information gleaned helping inform the Coastal Management Program for the lake.
The Coastal Management Programs will provide planning direction for the Wallaga Lake, Merimbula Lake, Back Lake, and Lake Curalo estuaries over the coming decade, consistent with the reformed coastal management framework in NSW.
Some of the key objectives of the new Coastal Management Programs include updating the understanding around estuary processes; considering how best to tackle the threats and pressures on the estuaries, and to protect and enhance their natural environment; and working with the community to find new opportunities for further improving the recreational amenity of the estuaries.

There was a hydrographical study of Lake Curalo (ICOLL) in October 2017, they mapped the bottom and checked sedimentation rates. That was 17 months ago and nothing has been mentioned about it. Eden elders like myself (72 years+) remember Curalo as being much deeper than it is now.This was considered anecdotal by council spokespeople who didn't appear to have much appetite for searching out, or disproving, empirical evidence for this claim. A future headmaster of Eden sank a catamaran with a 14 foot mast (14x12 =168/39.37=4.26metres, There was only 4 inches or 10 mils left sticking out of the water. We are keen to see what your researchers find, and how you will restore it to it's former glory before urbanisation on it's flood plains. Limnologists say for every increase in lake depth there is a four metre spread to the sides, without ample flood plains this will be interesting unless levee banks are put in place.
