Our new dam

Watch the live action at the construction site as Canberra’s enlarged Cotter Dam takes shape. The new dam will increase the capacity of the reservoir from 4 Gigalitres (GL) to 78 GL; almost 20 times its current size.This morning observations are that the dam structure is sound. Heavy machinery has remained safe and cranes are fine. Have lost some forms and scaffolding and some light equipment. Biggest concern is the washing out of earthwork on the downstream side (looking at damcam it is on the left abutment or the right hand side looking at the dam). Possibly be a week before we get back on the dam and looks like a three week clean up. Flood is a one in one hundred year event so top marks to the engineers. Now we wait till tomorrows renewed assault.
