Locals and water enthusiasts may notice a slight change to the River Murray’s water level from last week as a weir pool manipulation trial commenced last Friday to improve the health of the river and ecosystems.
The trial will lower and then raise water levels along the River Murray to partially mimic seasonal drying and wetting of the river’s wetlands and floodplains.
From last week, weir pool lowering will gradually occur at locks two (Taylorville), five (Renmark) and six (Murtho). Water levels will be lowered up to eight centimetres below normal pool level, and the lowering will stay within the normal operating range. Weir pool raising is expected to follow from mid-August until November, subject to the availability of environmental water.
The raising will increase water levels at lock two to 50 centimetres and lock five to 45 centimetres above normal pool level.
