Unsealed rural roads are potentially a major source of sediment entering waterways when it rains.
In the Noosa River catchment no specific measures of sediment contribution from rural roads has been
undertaken. Healthy Land and Water have identified that a critical factor in determining the contribution
of sediment from roads to waterways relates to the level of connectivity of ‘table drains’ entering these
receiving waterways. A table drain is a v-shaped, trapezoidal or parabolic-shaped surface drain located
immediately adjacent to the edge of a road.
This research has demonstrated that lowering connectivity to waterways requires that water is either
discharged from table drains or spread across vegetated landscapes where sediment can settle or the flow is
directed into detention basins for sediment settling.

Objective 7: Sediment, nutrients and contaminants moving from rural areas to waterways and
wetlands are reduced.
Objective 8: Degraded waterways, wetlands, riparian areas and in-stream habitats are rehabilitated.
Management response Who When
Develop and implement a targeted extension Council, NRM Groups, Medium term
and education program for rural landholders in Community stakeholders
