SUNWATER have started releasing water from Callide Dam.
The release commenced just after midday.
Water also started flowing over Kroombit Dam earlier this morning and at 1.30pm Kroombit Dam was sitting at 129%.
SunWater executive general manager of operations, Colin Bendall said overnight, heavy rain within the Callide Valley catchment caused inflows into Callide and Kroombit dams to increase significantly.
I stress that this is not predicted to be anywhere near as severe as the aftermath of Cyclone Marcia, and as of mid-morning on Thursday, rain had cleared the catchment," Mr Bendall said.
"To put this in perspective, in the last 36 hours we have seen 192mm of rain (since 1am Wednesday, March 29), compared with 250mm in just 3 hours during the Marcia event.
"We also started with Callide Dam at 62% capacity this time, compared with approximately 80% for the Marcia event. We are now starting to see inflows at the rear of the dam decreasing.
"We are monitoring the situation closely through our 24-hour Operations Control Centre, and we will continue to update the community as information comes to hand.
"Within the Callide Valley, this monitoring is being enhanced through the use of new gauging and rainfall stations upstream of Callide Dam.
"Across Queensland, we are working closely with Councils and local disaster management groups to provide tools and information to help people make informed decisions in the face of this extreme weather.
"SunWater also provides early warning information and updates on the SunWater App, SMS messages and social media updates, to notify communities living downstream of our dams of potential dam outflows."
