Subcatchments of the Stanley Catchment
- Eastern Stanley River
- Western Stanley River
- Southern Stanley River
The Stanley River is a tributary of the Brisbane River, joining the Brisbane just upstream from Wivenhoe Dam. The headwaters of the catchment begin in the relatively undisturbed forests of Jimna and Conondale in the Conondale Range, which separates it from the Maroochy-Mooloolah and Mary River Catchments. Some timbered areas are National Park and some are State Forest areas that have been selectively harvested. Most of the headwater streams in this area remain in excellent condition, with their diverse fauna and flora intact. The valleys, which were once open forest and grasslands, have been extensively cleared for cattle. The Stanley River catchment is principally a beef and dairying area. However, the best known product from the Stanley River catchment is its water. Lake Somerset has been supplying Brisbane residents and industries with water since the early 1950�s. Somerset dam divides the catchment into two segments: the bulk of the catchment upstream of the dam, including the headwaters; and the short, lower section below the dam.
