Toowoomba’s wet weather has led Perseverance Dam to overflow.
Toowoomba Regional Council is now keeping a close watch on the current weather situation with Perseverance Dam spilling.
At 9am this morning (December 18), the water level at Perseverance Dam, which was built in the 1960s, was recorded at 100.4 per cent.
Cressbrook Dam, a much larger dam that sits 10km downstream from Perseverance Dam, recorded water levels at 78.7 per cent.
Cressbrook, is now Toowoomba’s main source of water, has a specified desired target level of 70 per cent.
Toowoomba Regional Council Deputy Mayor Rebecca Vonhoff said while no flooding or community impacts were expected the council would continue to monitor the situation with further wet weather on the way.
“Perseverance Dam is one of the region’s main drinking water sources, spills into Cressbrook Dam and last spilt in December 2022,’’ she said.
“Cressbrook Dam is currently at 78.2 per cent and just over 3.5 metres below spillway level.
“Cressbrook Dam has been used as our main drinking water source since July 2024 to target a level of 70 per cent prior to construction commencing on the Cressbrook Dam Safety Improvement Project.
“While there is currently no activation of TRC’s Dam Safety Emergency Action Plan, we will continue to monitor the levels over coming days.
“To assist in the management of the water level in Perseverance Dam, Council will now temporarily pump out of Perseverance to supply water to residents connected to the Toowoomba Bulk Water Supply.”
Lake Perseverance, which has storage capacity of 26,944 ML, is the second largest reservoir servicing Toowoomba. At 100 per cent, Cressbrook Dam has a capacity of
79,266 ML while Cooby Dam only has a capacity of 19762 ML.
The Bureau of Meteorology expects Toowoomba will receive more rain this week but the forecasts for the next two weeks shows strong prospects for drier conditions.
