The country along the Cobrabald River is a rich grazing area used for rearing livestock.
The Walcha fishing club stocks this river annually and it is one of the best trout fishing rivers in NSW. A fossicking area is also available in a reserve just off the Niangala Road and along the Cobrabald River.
