Works will reshape Lake Eppalock spillway 'cliff'

Goulburn-Murray Water announced on Monday crews would be on site at the spillway for about 17 weeks.

The works will mean access to the Campaspe River track and public toilets at the spillway will be restricted. There will also be traffic control in place at times on Spillway Road.

G-MW's Warren Jose said more than $2 million would be spent on the project.

"This has caused rocks to fall into the drain beside the spillway and it's causing operational problems," he said.

"It's difficult for our people to access and inspect with the potential of small rocks falling out.

"So we've taken the view that we need to reshape the spillway and grade it back to a less steep angle, back to 45 degrees or shallowed.

"We'll use some fairly large excavators and some trucks to remove the rock and stockpile the rock on site further downstream.

He said clay material would be used to protect the face of the existing spillway.

"The rock itself is extremely strong - if you hit it with a hammer it will bounce back," he said.

"Protecting the spillway is very important - we don't want to damage an operating spillway."

Other news:

Lake Eppalock was about 35 per cent full and, Mr Jose said, there were no concerns about the dam wall's structure itself.

"By making the cliff face shallower it'll reduce the likelihood of rocks becoming loose and rolling down.

"That means it'll be safer for our people, it'll also prevent clogging or rocks rolling into the damage path and inspection points."
