Split Rock Dam is a rock-fill dam on the Manilla River in the North West Slopes region of New South Wales, situated approximately 70 kilometres north-west of Tamworth and 28 kilometres north of Manilla, accessed via a turnoff from Fossickers Way onto Split Rock Dam Road. The reservoir, known as Split Rock Reservoir, covers a surface area of 22 square kilometres, offering a substantial expanse of open water for paddling. The dam wall stands 66 metres high with a crest length of 484 metres, and the surrounding landscape consists of rolling countryside with extensive foreshores providing views across the lake.

Canoeing is among the water sports explicitly supported at the dam. The primary boat ramp is a concrete facility located at the main camping area on the western foreshore, approximately one kilometre north of the dam wall. A second gravel boat ramp is available at Glenriddle Reserve on the northern shore of the dam's upper reaches, providing an alternative access point for paddlers wishing to explore the upper sections of the reservoir.

The dam is managed by WaterNSW, and recreation areas are closed on all Total Fire Ban days, which is an important planning consideration during the warmer months. Drones and model aircraft are prohibited. There is no access to the dam wall itself.

The main camping area on the western foreshore offers unpowered unreserved sites as well as powered sites near the amenities block. Facilities include shower and toilet amenities, a fish cleaning table, wood barbecues, shelter, and picnic areas. The dam's name derives from a fissure in a large rock near the dam structure.

The reservoir supports populations of Murray cod, golden perch, silver perch, catfish, and carp, meaning paddlers are likely to encounter fishing activity on the water. The dam also attracts birdwatchers and bushwalkers, so the foreshore areas can see varied visitor traffic.
