Ellen Brook is an ephemeralstream which runs from south ofGingin to theSwan River in Western Australia.
The headwaters of Ellen Brook start south of Gingin, in theWheatbelt region. From there, Ellen Brook travels south, generally parallel and to the east ofBrand Highway, through agricultural land. NearMuchea, Ellen Brook passes under Brand Highway, Granary Drive andTonkin Highway. From there, it heads south, betweenGreat Northern Highway and Muchea South Road, passing to the west ofRAAF Base Pearce inBullsbrook, before reachingUpper Swan, where it passes under Muchea South Road, past residential areas inThe Vines andBelhus, before joining the Swan River in theSwan Valley.
Tributaries to the west of Ellen Brook are sourced by groundwater flowing from theGnangara Mound. Tributaries to the east have aquifers on theDandaragan plateau as their source.[1][2]
The brook only flows from May to December. At a size of 715 square kilometres (276 sq mi), Ellen Brook is the largest sub catchment for the Swan–Canning catchment, and one of the main sources of nitrogen and phosphorus for the Swan–Canning river system. The Western AustraliaDepartment of Water and Environmental Regulation monitors water quality in Ellen Brook.[3][1]
Ellen Brook is named after Ellen Stirling, the wife ofJames Stirling, who was the firstGovernor of Western Australia. In turn, the suburb ofEllenbrook, located near the mouth of the brook, was named after the brook.[4][5]
