The Water Corporation\u2019s contract for the reconstruction of the Logue Brook Spillway is proceeding as planned.\u00a0 The project commenced in November 2014 and is expected to be completed by the end of July 2015.\u00a0 Logue Brook dam is a 49 m high earthfill dam about 130 km south east of Perth that supplies water to the Harvey Irrigation District.\u00a0 Completed in 1963, the reservoir formed by the dam stores 21.7 GL.<\/p>\n
The project involves upgrading the existing side channel spillway from its existing nominal capacity of 25\u00a0m3<\/sup>\/sec to a flood capacity of 160 m3<\/sup>\/sec.\u00a0 The scope of work involves demolition of the existing spillway, excavation for the approach channel, crest structure, chute and stilling basin amounting to almost 100 000 m3<\/sup>, placement of 2000 m3<\/sup> of concrete, reconstruction of the bridge over the spillway and reinstatement of the road access across the crest of the dam.<\/p>\n Progress was delayed for more than a week due to severe bushfires in the region.\u00a0 While the fires did not directly threaten the site, there were no firefighting resources available to fight a fire if one broke out near the site.<\/p>\n <\/a><\/p>\n The site June 2015<\/strong><\/p>\n By early June the project had reached the stage where the final sections of the chute floor were being poured and preparations were in hand to place the access bridge.
