Silt Traps Harvest skid sites can be a major source of sediment run-off. Where drainage water from a skid site is discharged close enough to any water course to the extent it is likely to discolour the water course, it must be first discharged to a silt trap or a sediment retention pond. Drainage Stormwater that runs off skid sites to fill areas and birdnests on the outer perimeter usually D A I E SILT TRAP Drainage sloped to rear of skid site results in failure of the birdnest, skid sites or both. All drainage should be away from fill and birdnests, preferably to the back of the skid site. On Completion of Harvest Severe damage can occur to skid sites well after harvest contractors have finished. On completion of harvest from a skid site, drainage should be re-established away from fill. Slash should be pulled onto the skid site to remove the weight of the slash from the fill or scattered over the skid site platform. Bunds can be formed round the perimeter of the skid site to keep stormwater from the front edge if the skid site has a fall in that direction. 15 H C T AI N G DR
