==Suitable conditions==

* The rock that makes up the catchment should be bare and free of vegetation/soil. It should have no fractures or cracks that would result in aloss of water through seepage.* Site the dams for rock catchments to maximize the natural topography – to get the best volume, make dams on the lower side of existingrock pools.
