Maintaining reliable on-farm water supplies is an on-going challenge for landholders throughout Western Australia. Improving reliability of dams by constructing a roaded catchment is one of the most cost-effective methods of improving the performance and reliability of a farm water supply.
A roaded catchment is a water-harvesting structure designed to increase the amount of run-off from the catchment above a dam. The 'roads' of a roaded catchment are parallel ridges of earth with batters (or side slopes) that cause run-off to be directed into troughs or channels. The surface is lined with clay and compacted to make it smooth and impervious to reduce infiltration and increase run-off.
