Survey grade banks and tree lines and rip, drain and mound tree lines. Construct grade banks and receival drains when the valley floor is dry enough to carry heavy machinery. Earthworks Grade banks to control run-off and seepage discharging on to the valley floor may be required on the upper catchment. This would safely remove water to the waterway. Waterways Where natural drainage lines are poorly defined it will be necessary to construct an artificial waterway.
Waterways are well grassed areas designed to carry the discharge water flow safely downhill.
A banked waterway is easy to prepare. Topsoil is not disturbed. The banks are built from soil removed from outside the waterway. The width will depend on the size of the catchment discharging into the grade banks. Banks and firebreaks are spurred into the waterway.
