Bennett Brook's catchment area covers 217 square kilometres (84 sq mi). Approximately half of the catchment area is covered by Whiteman Park and the Gnangara Pine Plantation. The rest of the catchment is urbanised, covering the suburbs of Ballajura, Beechboro, Bennett Springs, Kiara, Lockridge, Malaga, Morley and Noranda. The tributaries to the west are highly modified and partially underground. The tributaries to the north are mostly natural.
Upstream areas only flow between August and November. Groundwater pumping from the Gnangara Mound has made the flow lower than the natural flow. Downstream areas flow year round. Urbanisation has made the flow downstream higher than the natural flow, due to higher surface runoff from roads and houses.
In the late 1930s the local authority, the Swan Road Board considered a bridge to cross the brook. In the 1980s, the status of the area relative to indigenous concerns and environmental concerns made bridge making and other activity more restricted.
