The main reason for that is for 30 years Junction Reefs has been officially closed, although during summer the area around the historic dam on the Belubula River near Mandurama has seen a few visitors breaching the fencing.

The good news now is that the Junction Reefs Crown Reserve is now open for the community to enjoy, guilt free and without needing to jimmy open a gate.

Also known as Belubula Dam, Junction Reefs Dam is a heritage-listed former mining dam designed and built by Oscar Shulze in 1896-7 to provide water and power to the nearby gold mine.

The dam was listed on the NSW State Heritage Register on 2 April 1999 and it was the first multi-arched dam to be built in Australia, and is unique to the state.

For those interested in historic engineering it is a marvellous structure, for everyone else though it's a tremendous place to enjoy a day out by the river.

Thanks to NSW Government funding of $23,480, grids have been installed at the entrance to Junction Reefs and Bakers Shaft Reserves.

Fencing has also been installed around the new toilet block.

"You can gain access off Bakers Road which comes off Burnt Yards Road," Deputy Chair Junction Reefs Land Manager and Blayney councillor Bruce Reynolds said.

"The public are asked not to go onto the southern side of the Belubula River or into fenced off areas that are clearly signposted."
