Bridging gap before ringing spillway bell

Work on the new Bowling Alley Point bridge near Chaffey Dam at Nundle has been completed, with the associated road works more than 80 per cent complete.

DONE BUT NOT DUSTED: Work on the new Bowling Alley Point bridge is completed, but associated road works are still underway near Chaffey Dam.

WaterNSW says preparations are now underway for raising the Morning Glory Spillway bell mouth by 6.5m, with more than 200 of about 1600 holes drilled to house anchor bars that will tie the new concrete section onto the existing spillway.

The government agency said the first layer of vertical wall panels had been installed, with fill currently being placed in between panels.

A spokesman said the dam and associated works had not been affected by recent inflows and the subsequent increase in storage level to Chaffey and the project is continuing on program and to budget.

The $50million Chaffey Dam upgrade project will see the dam wall raised to augment the capacity by some 60per cent to 100,000 megalitres.

Yesterday the dam capacity stood at 52.5 per cent, having seen another 82 megalitres of inflow overnight to Friday. The dam was holding 33,607 megalitres, its highest level in 18 months.

The new bridge is a five-span, 145-metre structure.
