Split Rock Dam, located about 14 kilometres north of Manilla and 25 kilometres south of Barraba in New South Wales, is a popular inland recreation destination on the Manilla River.

The dam operates alongside Keepit Dam to supply water for irrigation, environmental flows, and household needs in the Namoi Valley.

The main camping area sits approximately one kilometre north of the dam wall on the western foreshore, offering both powered and unpowered sites with lake views, wood barbecues, toilets, picnic shelters, and a fish cleaning area.

A concrete boat ramp provides access for water sports enthusiasts. Glenriddle Reserve on the northern shore offers additional unpowered camping with a gravel boat ramp.

The area is well suited to fishing, with golden perch, silver perch, and catfish among the species present. It draws water skiers and birdwatchers as well, though the experience can vary depending on current dam levels.
