A COMPREHENSIVE plan to deal with the flood risk to rivers and lakes in the Lockyer Valley has been launched.
The Lockyer Catchment Action Plan is part of the Resilient Rivers Regional Strategy and the plan identifies priority area of work in catchments throughout the valley.
The primary focus of the plan is to address the "very high risk" of sediment movement from catchments as identified in key investigations into the 2011 flood event and January 2013 weather events.
The threat to the water supply of Brisbane arising from very high sediment loads in the Brisbane River in the 2013 event was identified as a matter of particular concern.
The loss of soil resources in the Lockyer Valley were identified as a major concern given the region produces 19% of Queensland's vegetable crops at an annual value of $260 million.
Reports show the 2011 and 2013 floods devastated the catchment and its community.
The impact on infrastructure alone was extreme with greater than $12 million of repairs occurring in Tenthill Creek sub-catchment alone.
Documents show infrastructure in the catchment is highly vulnerable to damage, with floods causing damage to railway trucks, closing down rail movement for Queensland coal to ports.
Damage to the Warrego Hwy, particularly below Toowoomba, also caused major disruptions.
The Council of Mayors (SEQ), of which Toowoomba Mayor Paul Antonio is deputy chair, launched the plan this morning at Lake Apex.
Parts of the Toowoomba Regional Council area are included in the plan.
Key creeks included in the plan include Ma Ma, Tenthill, Sandy (Forest Hill), Laidley, Flagstone, Lockyer, Murphys and Gatton Cks.
