Stanley River (Queensland)
Stanley River downstream from the Somerset Dam
|Mouth||confluence with the Brisbane River|
|Basin area||1330 km² |
The Stanley River in Queensland is the main tributary of the Brisbane River. The Stanley River valley extends roughly 35 km westwards from the area south of Maleny, through Woodford to Kilcoy before veering southwards.
It is dammed by the Somerset Dam built seven km upstream from its confluence with the Brisbane River. The dam was the principal water supply for Brisbane for some fifty years until the construction of the Wivenhoe Dam was completed, forming Lake Wivenhoe.
Before either dam was built the Stanley and Brisbane Rivers were both prone to flooding. Despite warnings instigated by Henry Somerset who saw flash flooding in the upper reaches of the Stanley River valley, the 1893 Black February floods caused severe flooding downstream in Brisbane and other towns such as Fernvale. The 1893 floods occurred after heavy rains near Peachester.
The river once marked the north-west boundary of the defunct County of Stanley.
Flora and fauna
Riparian vegetation around the Lake Somerset area have been almost completely cleared for grazing. In the upper reaches bushland remains mostly intact although wildlife corridors have been fragmented and fish stocks reduced.
