The North Pine River rises in the D'Aguilar Range in the Mount Mee State Forest, approximately 50 km (31 mi) north-west of Brisbane, and flows generally south-east to form its confluence with the South Pine River at Lawnton, where the river forms the Pine River. The river flows mostly through the Moreton Bay Region, just to the south of Dayboro.
The headwaters of the North Pine River are steep, flow through the D’Aguilar National Park, and receive very high rainfall over mostly fractured metamorphic rocks. Surface water runoff is high and creek flow is fast. Fractures in the metamorphic rocks and alluvium in the channel provide for some local groundwater recharge.
Along with Kobble Creek it is dammed at Whiteside to form the North Pine Dam, an artificial lake called Lake Samsonvale. After the North Pine Dam, the North Pine River continues through the suburbs of Petrie and Lawnton, where it meets with the South Pine River and forms the Pine River, flowing into Bramble Bay. The river descends 470 metres (1,540 ft) over its 54 kilometre (34 mi) course.
The river moves very slowly and water can take 25 days to move from A. J. Wylie bridge to the mouth. The northern bank can flood after water release from the dam, including Gympie Road and the railway line. In this area the southern bank is steep with some scours/erosion. There are also several large water bodies along the North Pine River, associated with historic sand mining, including Black Duck Creek dam.
