TAS Country : January 27th 2011
Friday, January 28, 2011 Tasmanian Country 3 Farm dam damage alert ABOVE: DPIPWE's Terry Leary, right, inspects a dam at Sassafras with farm owner Ian Young.

JENNIFER CRAWLEY 'Spillways need to be clear of any build-up of debris and checked to see if they have suffered any serious erosion.' FARMERS are being told to check dam walls after record-breaking rains seriously damaged several dams on the North West Coast two week ago. Breaches were discovered in four dams across the region with police and emergency services monitoring them during the floods. Department of Primary Industries, Parks, Water and Environment water management officer Terry Leary said farmers needed to check if there was any damage to dam embankments especially crests and dam batters. ''Farmers need to look for seepages or areas of erosion and washouts,'' Mr Leary said. ''Spillways need to be clear of any build-up of debris and checked to see if they have suffered any serious ero- sion.'' Mr Leary said spillways needed to be three to four times bigger to cope with the amount of water that fell in the 24 hours to Friday January 7. He said that spillways designed to cope with a one-in-25 year or a one-in- 50 year flood had to cope with a one-in- 100 year event. Dams that were well built and well maintained handled the heavy rainfall well. ''But every farm dam in this area was spilling and a large number of them overtopped,'' Mr Leary said. ''Their spillways simply couldn't cope.'' Mr Leary said there had been so much rain during the summer months that little irrigation was used and all the dams were full. ''Other times they would be half full,'' he said. Mr Leary said if farmers had serious concerns about dam safety they should engage the services of an engineer as soon as possible. He said they should also contact their local regional DPIPWE water management officer. Mr Leary said no crops were lost due to dam failure. ''It's hard to generalise what damage the failure of a dam contributed to the extent of the flood. ''When the dams failed the stream endured one of its biggest flows.'' Mr Leary said farmers were entitled to undertake minor repairs like putting topsoil back that had washed off the embankment. But he said major flaws needed to be reported to DPIPWE. Primary Industries, Parks, Water and Environment Minister Bryan Green commended property owners, emergency services and DPIPWE offi- cers for their response to the floods. ''Their quick, cooperative action un- doubtedly prevented widespread dam- age,'' Mr Green said. Mr Leary said DPIPWE staff would be out in force checking as many dams as possible.
