Stream SC is a strong intermittent reach that originates at a large headcut
inside the study area and runs west, offsite. It is primarily comprised of pooled
water and the banks of the stream are heavily eroded, creating vertical banks.

Stream SB is a short perennial channel that is primarily fed by a stormwater
outlet from the adjacent residential areas. The stream is incised and downcut,
especially in the pools, allowing the hydrology to be influenced by groundwater
as well. Stream SB flows west into Booker Creek, within the study area.
